All perfect. Quality is 4.5 on 5 but quality to price ratio is excellent.

I have had an great experience ordering from Wolfy! The communication was always quick and clear. Adding parts to your order after you made your payment is also accepted by Wolfy. They are also willing to hold your order for a little bit if you need time to decide what additional parts you would like to add. I ordered compression fittings.

Latest company news about What Are the Valves Commonly Used in Gas Pipeline Control System

Wofly will introduce the valve parts commonly used in the gas pipeline control system.

 

Safety valve: it is normally closed under the action of external force and is the disc part of the system.When the medium pressure in the equipment or pipeline rises beyond the specified value, the medium pressure in the pipeline or equipment can be prevented from exceeding the specified value by discharging the medium outside the system.The safety valve is an automatic valve, which is mainly used for boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. The safety valve can only be used after pressure test.

 

Pressure Regulator:pressure reducing valve(also known as reduced pressure regulator valve), pressure reducing valve is a valve in the body of the opening of the disc of regulating the flow of medium, the medium pressure is reduced, at the same time with the aid of the role of the valve after pressure adjust the opening of disc part, keep the valve after pressure within a certain range, under the condition of the inlet pressure changing, keep the outlet pressure within the scope of the set. And protect the means of production behind it.

Pressure Reducer (Pressure Reducing Valve): the pressure reducer is a valve that reduces the inlet pressure to a required outlet pressure through regulation, and automatically keeps the outlet pressure stable by relying on the energy of the medium itself. From the perspective of hydrodynamics, the pressure reducer is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow rate and kinetic energy of the fluid can be changed, resulting in different pressure losses, so as to achieve the purpose of pressure reduction. Then, depending on the regulation of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve remains constant within a certain error range.

 

What valve parts of gas pipeline engineering will be introduced here first. Gas pipeline includes control valves, filters, pressure reducing devices, pressure gauges, flowmeters, online analyzers, etc., which should be concentrated in the gas inlet chamber.
