Most Common Valves Used in Piping Systems
A valve is merely a device that directs or controls the flow of fluids by opening, closing, or partially obstructing passageways. Valves are contributory in everything from pushing soap out of a machine to starting a jet.

You can’t be an expert in pipe fittings manufacturing without being an industrial valve fitting manufacturer expert, as well. Without valves, there would be no control of the flow in the pipes. Here are about types of valves and their applications.

1. Gate Valves
These are the most common type of valve fitting in the following industries such as gas, oil, petrol pharmaceutical, these are valves that open by elating a gate out of the route for the fluid. Gate valves are planned to be fully open or closed; they are frequently used as a block valve for segregating pipe systems.

There is no obstruction in the flow path resulting in very little friction loss, while a gate valve is open. Gate valves are used when a straight-line flow of fluid and the smallest restriction is desired.

These can be measured by a hand-wheel, air motorized ...
... diaphragm, electric motor, or a piston actuator.

2. Globe Valves
Globe valves are one of those valves that are used for regulating the flow in a pipeline, instead of having the “all or nothing” function of a gate valve. The following valves regulate by the location of a movable disk in relation to the stationary ring seat.

A globe valve may have parts that run straight across, and also can be pointed at an angle. This type of angled supply valve is commonly used for a corrosive environment. Having openings on an angled supply valve that point downhill helps the fluid to drain off to prevent clogging.

3. Butterfly Valves
The butterfly valve is considered to regulate flow, but with limited control ability. This is a simpler manufacturing valve fitting that is easily functioned by rotating a handle 90 degrees. The butterfly valve has not usually been thought to give an optimistic shut-off, however, modern expertise has eased the assembly of a bubble-tight shut-off.

4. Check Valves
Check valves, also distinguished as NRVs (non-return valves), permit fluid to flow in a single direction only. Their persistence is to prevent backflow. There are several types of “stoppers” that avoid backflow in check valves. Ball check valves and piston check valves function by requiring a minimum amount of incoming flow pressure; backflow is not powerful enough to lift the ball or piston back up to travel the other direction.

5. Relief Valves
The relief valve also called the safety valve, it is an industrial valves fitting connected to set a limit on the quantity of pressure in a system. This type of right-angled supply valve is severely for averting over-pressure that could cause harm to the system.

6. Needle Valves
The needle valve is basically a variation of the globe valve used for very fine control of flow in the pipes. Needle valves contain a lean, tapered plug, as different to the globe valve’s larger and less precise disk.
