An Inside Story: Working in Outside Sales at GVC

Has anybody ever asked you if you would be interested in working in Outside sales? You might be dreading it as going door to door isn’t a dream job, or Is it?  While I do know people like that, I am here to tell you that not all outside sales are created equal. I had the pleasure of speaking to one of GVCs Outside sales ladies and she had the pleasure of telling me what actually happens when she does get a chance to go and see clients.

1. What time of day is the best time to visit clients? The best time to visit your clients is in the morning 9am or sooner.  They don’t have tons of people needing their assistance right away and it’s just a good time because people tend to be calmer before the storm (rush of work). 

 2. How often should you be visiting your clients?  For your major clients that you do lots of business with it is nice to visit them or treat them at least once a month or every two months.  If not visiting them definitely socializing with them via email.

 3. How do you know if this is the right client for your company? In regards to GVC we are the manufacturer so I try to aim for clients that are in Procurement, Engineering, Inside Sales, Purchasing, and also reaching out to Project Managers or Estimators. You can go to the prospects website and see exactly what their form of business is.  I know I have the right contact (client) when they say they use or sell Valves for their clients OR projects.  Most of the time I deal with several clients that have their own clients. 

 4. How important is it to have an inside sales person when you are doing outside sales?  It’s extremely important to have a responsible and quick Inside Sales person.  The Inside Sales rep that is assigned to you needs to know the product line well and is good with documentation and communication.  An important task for the Inside rep is to CC the Out Rep, so that the Out Rep knows things are being handled without having to ask unnecessary questions.

 5. Is it better to make appointments or just walk in?  Personally, it is better to make appointments – many people do not like reps to just walk in. It is better because when you are on the schedule, you have a chance to meet other people that are in the office and you don’t force yourself on major clients – Now with supply companies that are a bit smaller or you “just so happen to pass by a company with potential” I don’t think it’s a big deal.

 6. Name one reason why you are proud to work at GVC?  I’m proud to work at GVC because our longevity of our product is outstanding, and our documentation is a point to be proud of.  I’m also just blessed to work with a company that is like a small family to me. I have been here for 5 years am always learning something here.  I believe that we have a product that can make a huge punch.  We stand up against the big guys FOR SURE!!

 7. What is a successful day when you’re working as an outside sales person? A successful day to me is getting plenty of business cards when I visit a company to bring them breakfast or visit their office. I also enjoy shaking many hands and generally have several different conversations. I’m putting myself as well as my company out there and trying my best so that makes me feel great.

8. Last question, what do you do when you get back into the office from seeing a client? When I get back into the office it is important to add all the new business cards to my outlook address book, this assures that if the card/s get misplaced I still have the contacts info. Afterwards, sending out Thank you e-mails is definitely a must!

Gearbox installation on a Trunnion Ball Valve

Gearbox installation on a Trunnion Ball Valve

Installing a gear box on a Trunnion ball valve is no easy task. In fact, if you want to learn be ready to get your hands messy. It is recommended to buy some gloves that are suitable to wear for the lubrication process. Remember to always consult the manufacturer first.

Start by generously lubricating the stem of the valve. We use an industrial high-performance grease that works with the same temperature ratings as our valve.

Apply grease to the stem, stem key, and dowel pin and insert the stem key into the stem slot. The dowel pin will be inserted through the stem key and into the stem to hold the stem key in place within the stem slot.

Apply the grease to four (4) of the bolts and insert them into the mounting pad in the holes closest to the end flanges. This is necessary due to having less clearance to insert these four (4) bolts after the gear is installed due to the curvature of the valve body.

Once it is generously lubricated the gearbox should fit easily over the stem and stem key. Inside the gear housing there is a slot that fits the assembled stem and stem key. You need to ensure proper alignment of the slot in the gear housing with the stem and stem key. The travel stops may need to be loosened and the wheel turned in order to properly align the bolt-holes in the bottom of the gear housing with the bolt-holes through the mounting pad.

Next, insert the other four (4) bolts through the bottom of the mounting pad and thread them into the bottom of the gearbox, also threading in the four (4) bolts that were inserted into the mounting pad at an earlier stage. Next, add the washers and nuts to the bolts and tighten them down. Once you have installed the handwheel be sure to operate the valve one full cycle and adjust the travel stops accordingly to the open and closed positions. This means turning the handwheel to go from its fully open position to fully closed position, adjust the travel stop for the closed position. Then turn the handwheel back the other way to go from its fully closed position to fully open position, adjust the travel stop for the open position.

Double Block and Bleed Valves

The Double Block and Bleed is a special feature that you can find among our Trunnion Ball Valves and Expanding Gate Valves. The idea of having DBB was first created by engineers. According our our ValveMD, “The DBB feature of the valve or valves is the ability to segregate two pressure sources and to bleed/vent pressure in the void between the two sealing elements (blocks). The bleed may be in the pipework/pipeline when two valves are used, or in the valve body between the two seats when the valve has the Double Block and Bleed (DBB) feature.”

You may find Double Block and Bleed valves in many types of industries, including; Gas and Liquid pipelines, Production, Processing Oil and Gas, and more. This feature ensures zero leakage which is why they are popular in pipelines. 

Do not be confused with Double Isolation Bleed which according to API means, “API 6D defines a Double Isolation & Bleed Valve (DIB) as a “single valve with two seating surfaces, each of which, in the closed position, provides a seal against pressure from a single source, with a means of venting/bleeding the cavity between the seating surfaces. The note adds that this feature can be provided in one or in both directions.”

For any questions regarding our Double Block and Bleed Valves, be sure to reach out to one of team members.

Types of Ball Valves

Types of ball valves :

 

Different types of bores for ball valves – full port, reduce port and V-port. These three types have different constructions and purposes.

 

  1. Full Port Ball Valve – A full-port, also known as a full bore, ball valve has a bore internal diameter (ID / inside diameter) approximately equal to the pipeline ID. This allows for reduced friction and pressure loss across the valve. With a full port ball valve there is NO restrictions to the flow of medium, but the valve can be more expensive. This type of bore is ideal for situations where pigging may be necessary. Global Valve & Controls (GVC) series CFS and 2T/3T split body and welded design, full port, flanged ball valve combines its sealing technology and design expertise for over 25 years with the versatility to solve even the most demanding applications . This technology and expertise is widely used in the chemical, pulp and paper, petrochemical, food and beverage and refining industries.
  2. Reduce Port Ball Valve – A reduce-port, also known as a reduce bore, ball valve is a valve in which the bore is reduced to one or two nominal sizes lower. This provides a more restricted flow path, generally resulting in higher energy losses. Global Valve & Controls (GVC) series RCFS and R2T/R3T ball valves offer both full port and reduce port valves. Known for its design features , superior sealing areas and various stainless alloys , the GVC brand is widely recognized as a leader in providing valve and flow control solutions for the energy , and oil and gas industries’ for a general all around great product and a fair price.
  3. V- Port Ball Valve – A V-port ball valve has either a “V” shaped ball or a “V” shaped seat. This type of valve also is known as a control valve in which the flow velocities need to be controlled / regulated as required per the application.

In closing Global Valve & Controls ball valves can be used in a variety of applications and markets, such as pipeline transmission, pig launchers, storage facilities, pulp and paper facilities , food and beverage , gas processing , industrial, and many more . Troy Richard, founder of Global Valve & Controls (GVC) explains that ball valves provide reliable leak protection and fugitive emissions concerns. Ball valves can be open and close quickly in which saves time and money on all automation packages.

Keeping your valves in check

Purchasing valves can be a major headache for some. For starters, one must know what kind of valve they are in need of and whether or not it fits their application. The following questions should be asked in order to find the proper valve;

–          What is the media?

–          What is the temperature?

–          What is the pressure?

–          Is it an open or closed position?

From there, the manufacturer will have a better idea of what the end user is really looking for. Many times, the manufacturer will find an error and will need more information to provide the best valve.

Once the valve is picked up and has landed in the end users hands, maintaining the valve is the next step. Many people think that once a valve has arrived it is placed in line right away, but this is not the case. Many steps are taken to insure the end user has received the order as they will have many shipments in one day. Step such as;

–          Ensure the valve, actuation and valve control accessories bill of materials matches the end user’s specification sheet.

–          The exterior of the valve and components checked to make sure it was not damaged in transportation

–          Ensure the valve process connections are covered (See article for more details)

Once the valve is “in line”, “stroking the valves and applying general-purpose lubrication at least once a month provides longer-term benefits in the functioning of in line valves”.

The incidence of leaking valves immediately following installation occurs too often, with the blame placed on the valve and its manufacture instead of the end user’s misapplication.” Making sure to follow policy and procedure and taking preventative steps will help get the right valve for the right job without any problems.

Lubricants for Your Valves’ Gearbox

Theory: Cold weather dictates a different type of lubricant to avoid seizure and promote proper function inside the gear housing.

Global Valve and Controls states, “in order to have a proper functioning valve it is necessary to use the correct grease inside the gear housing.”

In a case study where non-cold rated grease is applied to a valve that is heading to Wyoming, where the weather can be frigid seven months out of the year; the likelihood of the valve seizing becomes increased and the average lifespan potential will decrease.

Aftermath: It is a wise decision to consider the environment that your purchased valve will be applied to. With Global Valve and Controls, these are questions we ask our customers to protect their investment in order to increase the longevity of their valve; like a vehicle, it is important to use the recommended lubrications and oils to ensure proper performance. Valves are the same way. Moving parts need the correct lubrication to operate proficiently.

Fact: Materials such as grease or oil, are affected greatly by weather, hot and cold. However, lubricants can be engineered to withstand various environments by being structured to hold their viscosity.

What are Actuators?

What are actuators?

What are actuators and how do they work? There are four types of actuators that are used today.  The most commonly used in this industry are the Pneumatic and Hydraulic actuator.

hydraulic actuator consist of a cylinder or fluid motor that uses hydraulic power to facilitate mechanical operation. The mechanical motion gives an output in terms of linear, rotary or oscillatory motion. Because liquid cannot be compressed, a hydraulic actuator can exert considerable force, but is limited in acceleration and speed.

pneumatic actuator converts energy formed by compressed air at high pressure into either linear or rotary motion. Pneumatic energy is desirable for main engine controls because it can quickly respond in starting and stopping as the power source does not need to be stored in reserve for operation.

You may wonder what this means in English? Well, in simpler terms; the main difference between the two is that pneumatic actuators use air to transmit force while a hydraulic actuator will use liquid to transmit force. Depending on the media of your project will depend on what kind of actuator you will need.

This picture shows an example of what a pneumatic actuator might look like with a ball valve. A Pneumatic scotch yoke Automation package along with our ANSI 1500 Trunnion Ball Valve going for Natural gas service.
