The valve is a control component in the fluid delivery system, with diversion, shutoff, regulation, throttling, to prevent backflow, the valve is a control component in the fluid delivery system, with diversion, shutoff, regulation, throttling, reverse flow, Overflow relief and other functions. The valve acts as an important control element for the pipe. Pipeline system

Choose the most suitable valve is very important, related to the safety of the pipeline, loss of traffic, cost, etc., must be familiar with the characteristics of the valve and select the valve steps and basis.

At present, China's valve industry has been able to produce a wide range of gate valves, globe valves, check valves, ball valves, butterfly valves, throttle valves, plug valves, diaphragm valves, safety valves, regulating valves, traps and special valves; The maximum working pressure is 600MPa, the maximum nominal diameter of 5350mm, the maximum working temperature of 1200 ℃, the minimum working temperature of -196 ℃, the media for water, steam, oil, natural gas, strong corrosive media (such as concentrated nitric acid, Concentration of sulfuric acid, etc.), flammable media (such as stupid, ethylene, etc.), toxic media (such as hydrogen sulfide), explosive media and radioactive media (metal sodium, - pure water, etc.). Stainless steel cast iron, cast iron, forged steel, high and low alloy steel, stainless steel acid resistance, Hastelloy alloy,

Inquire nickel ore, Monel alloy, duplex stainless steel, titanium and so on. And to supporting the production of various electric, pneumatic, hydraulic valve drive device.

In the face of such a large number of valve varieties and such a variety of complex conditions, to choose the most suitable for the installation of the pipeline system valve products, first of all should understand the characteristics of the valve; Second, the master should select the steps and basis of the valve; the rules.
