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…

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…

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…

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.   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,…

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.…

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…

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. A 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. A pneumatic actuator converts…

Global Valve and Controls has become one of the newest organizational members of ASTM

Created in 1898, ASTM International has become one of the largest voluntary standards developing, not-for-profit organizations in the world. ASTM provides a forum for the development and publication of voluntary consensus standards for materials, products, systems, and services from its members. The members of ASTM represent producers, users, consumers, government, and academia from over 100 countries and are responsible for the development of technical documents that are the basis for manufacturing, management, procurement, codes, and regulations. What is a standard? As used in ASTM, a…
