Valves are very common in industrial installations, especially petrochemical applications, playing a very important role, which is the regulation, control the normal operation of production equipment indispensable key part, but the variety of valves, the selection of numerous factors need to be considered. For example, the nature of the fluid: gas, liquid, solid powder, etc., and the function , pressure, etc.


Valve selection requires comprehensive consideration , the first need to consider is functions, such as cut off, regulation, check, diversion and others, according to the characteristics of the fluid medium, temperature, pressure, corrosion, flammability, the size of the pipe to determine the valve material, according to the valve operating torque size to determine the mode of operation.



Normal temperature, pressure fluid media, cut-off valve usually choose gate valve, globe valve. Requirement of rapid closure should choose ball valves, ball valves are divided into soft seal and metal hard seal, RPTFE seat seal can be applied to 200 ℃ working conditions, 200-250 ℃ should choose PEEK seat of the ball valve, more than 250 ℃ should choose metal seal seat of the ball valve.

For large diameter valves, you can choose butterfly valves, butterfly valves are divided into soft seal and hard seal. Soft seal valves have rubber lined valves. For the medium with temperature over 200℃, metal sealed triple eccentric butterfly valve should be selected.




The relative products are: pneuamtic valves, electric valves, stainless steel ball valve, butterfly valve, gate valve, globe valve, check valve, Y strainer, pneumatic actuator, electric actuator, automatic valve components......
