Chemical Composition chart Stainless Steel
One of our Sales reps created a chart to show the different kinds of stainless steel and how they are created. When ordering Ball, Gate, Globe or check valves it is important to know what grade of stainless steel you are looking for.
*304 IS BEST FOR WELDING, USED FOR NON SEVERE APPLICATIONS
316 IS SUPEERIOR TO OTHER SS COMPOSITE; BEST FOR CHEMICAL CORROSIVE APPLICATIONS
316 SS HAS 2% MOLYBDENUM; 304 SS DOES NOT. THIS 2% MOLYBDENUM IS WHAT MAKES 316 SS CONSIDERABLY MORE RESISTANT TO CORROSION AND OXIDATION. PHARMACEUTICAL CHEMICAL MANUFACTURING MUST HAVE THE 316SS SO THAT THERE IS NOT EXCESSIVE METALLIC CONTAMINATION.
A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. A globe valve is a mechanism used to control or stop the flow of liquid or gas through a pipe. The seat of a globe valve is in the middle of and parallel to the pipe, and the opening in the seat is closed off with a disk or plug. Globe valves can be structured to handle flow in either direction.
A globe valve is formed by a baffle that splits the interior of the pipe, usually parallel to the length of the pipe. The baffle contains an opening that is sealed by means of a disc or flat plug being pushed down into the opening, or seat, perpendicular to the pipe, to stop the flow through the pipe. A structure called a bonnet outside the pipe holds a stem that is connected to the disc. A hand wheel at the top of the bonnet is used to manually screw down the stem with the disc at its end until the disc seals against the seat opening. In large industrial applications, a globe valve may be sealed using an electrical, pneumatic, or hydraulic actuator instead of a manual hand wheel.
These devices are sometimes referred to as throttle valves because they can reduce the flow through the pipe. If the sealing disc is moved part of the way toward the seat opening, the space through which the product can flow is limited and therefore the flow is limited. This type of valve offers good control to regulate the flow of liquid. Water pipes are often fitted with a globe valve so the operator can control the flow of water through the pipe by opening the valve only partially or all the way.
This valve can also be set up to close with or against the flow of product. If the product flows in the same direction that the disc is closing, the flow will aid the closure of the seal but make opening harder. Conversely, if the flow goes against the direction of the disc closure, it will be easier to open the valve and more difficult to close it.
The baffle inside a globe valve causes the product to divert its direction to move through the baffle. This angled movement means that the product cannot flow as freely and causes a pressure drop after the valve. Globe valves are generally unsuitable for slurries or thicker substances that can be impeded by the baffle.

Comparisons Between a Gate Valve and a Ball Valve
The prosperity of the valve industry has been shown in many fields. Actually, there is great variety of the types of the valve. All these types are making their own contributions to the development of the whole modern industry. As we all know, valves are made to control the flow of gases, liquids and granular solids in many systems. In order to meet various requirements, valves are designed and manufactured with a wide range of the types, sizes, materials, working temperature and pressure and means of actuation and so on. At this moment, we take the type of the ball valve and gate valve out for a comparison.
Firstly, the structure differs. As we all know that a ball valve features the spherical closure element with a round or other-shaped hole in the middle and a gate valve features the lifting and dropping wedge. And the number of the holding ports varies. A gate valve has two ports, which is called an inlet and an outlet. But a ball valve usually has two or more ports. However, when referring to the connections to the ports, they would be with the same ones, including the threaded, soldered or flanged connection.
Secondly, a gate valve and a ball valve vary at the mean of the actuation. Commonly speaking, a gate valve is typically with manual operation. Such is from the consideration of the precise isolation of the flow. Except from the manual operation, a ball valve is also able to be driven by the electric and pneumatic actuators.
At last, the flow, which under control by the two types of the valve, turns out to be with different characteristics. Due to the specially designed structure, a gate valve is not suitable to be opened and closed partially. As a result, a gate valve is required to shut the flow off in time in many available systems. At the same time, a ball valve is mainly designed to be able for the regulating situations. The flow is closely proportional to the rotation of the spherical device with a hole in the middle of it.

Balance holds ultimate importance in life. Our body is also blessed with natural barriers taking care of each and every organs. The most important organ, heart has valves which direct the flow of blood and take care that it does not flow in reverse direction.
Men's intelligence has beautifully drawn the natural activities which take place in our body and are carefully implemented in our daily activities for ease and convenience. These equipments are outstanding creations which have fulfilled industrial demands and are proving excellent equipments due to their applications which are delivered by them.
Industrial valves or controllers are the devices which are used for regulating the flow of fluids such as gases, liquids or slurries. The direction of fluid in an open valve is from higher pressure to lower pressure. These are mechanical devices which are fabricated for variety of purposes including industrial, military, commercial, residential and transport.
Amongst various types, controllers have wide range of usage which include oil and gas, power generation, mining, chemical manufacturing, chemical manufacturing and water reticulation. They play big role in all these industries leading to development of nation.
Controllers are truly blessings for many commercial as well as domestic activities. Industrial valves are of various types such as Ball, Gate , Swing Check, Globe, Butterfly etc. Amongst various types, Ball adjusters are widely used having passage which give way to passing fluid. These types have single passage. Steel, high pressure and Stainless steel valves are the most common types.
Stainless steel valves are benefiting many industrial activities. Stainless steel is used as basic material making these equipments durable and reliable. Stainless steel is anti-resistive, anti-corrosive and also offer great resistance to chemical reactions. These controllers are available in different shapes and sizes. Valve manufacturers have well acknowledged the needs of many industries and their processes. Full fledged companies have enabled the discovery of versatile industrial valves.
Advance technology and skilled men have really boosted the manufacturing of valves. Valve manufacturers have equal and important role in developing many companies.
Controllers are the best way to control and are excellently taking care of various process. They may be disposable or may be very huge but are amazingly feeding their purpose of creations.

Ravi Doshi is well known writer of Valve manufacturers and industrial valves. He has write a many books and article on industrial valves, Valve manufacturering and Stainless steel valves.
Popular industrial valve types are
"Ball Valves
"Gate Valves
"Swing Check Valves
"Globe Valves
"Butterfly Valves.
Let's explain briefly about these valves.
Ball Valves
It's ball placed inside a passageway that gives way for passing of fluid. A most common ball valve is a two way valve. This valve has a single passage way. Three way valves are less used.
Other types of ball valves
"Stainless steel Ball Valves.
"Steel Ball Valves
"High pressure ball valves.
Gate Valves
Gate valves control the flow of fluid and they are used when there's a minimum flow needed. It is also known as a sluice valve because the part that either stops or allows flow through the valve acts somewhat like a gate. Gate valves normally have flanged ends which are drilled according to pipeline compatible flange dimensional standards.
Just like any other valves, Gate valve too have flanged ends in order to connect them to the pipelines. The valve can be made of stainless steel, gun metal , cast iron or cast carbon steel.
Globe Valves
Globe Valves are spherical in shape and so the name "Globe Valves'. However, the newer globe valves are not so much spherically shaped. Globe valves offer greater precision than other valves when it comes to regulating flow. Globe valves are used in applications where flow needs to be finely tuned. Globe valves have a plate with a hole in it, and a disk or plug completely or partially fits into the hole, slowing or stopping flow, according to Peco Valve.
Swing Check Valves
Swing check valves are less used when compared to other types of widely used valves namely Ball valves, Gate Valves and Globe Valves. Under reverse flow conditions the swing check is held firmly against the valve seat, preventing system losses.
Swing check valves are good for keeping the pump primed when the power is off. They prevent water from backflowing from the filter into the pond. They are available in many sizes and have different types.
Butterfly Valves
Butterfly valves are one of the widely used valve types. Butterfly valves consist of a circular plate with a rod through it's diameter. The name "butterfly valve' is bacause of the appearance of the valve.
A butterfly valve only rotates 90 degrees. This means it can turn from completely blocking the flow of whatever is in its pipe to letting through as much as is possible.There are different kinds of butterfly valves, each adapted for different pressures and different usage.
Other widely used Valves are Forged steel valves, Forged steel gate valves.
