Valve fitting fittings

Valve (valve) is used to control a variety of pipelines and equipment in the gas, liquid and containing solid powder gas or liquid medium such as a device.

The valve is usually composed of valve body, valve cover, valve seat, opening and closing parts, driving mechanism, sealing and fasteners. The control function of the valve is to rely on the driving mechanism or fluid to drive the opening and closing parts to lift, slip, swing or rotation ratio to change the size of the flow area to achieve. Valve according to the material is also divided into cast iron valve, cast steel valve, stainless steel valve, chromium molybdenum steel valve, chromium molybdenum vanadium steel valve, dual phase steel valve, plastic valve, non-standard custom valve material. According to the driving mode of manual valve, electric valve, pneumatic valve, hydraulic valve, etc., according to the pressure can be divided into vacuum valve (less than standard atmospheric pressure), low pressure valve (P≤1.6MPa), medium pressure valve (92.5 ~ 6.4MPa), high pressure valve (10 ~ 80MPa) and ultra-high pressure valve (P≥100MPa).

Valve is a control part of pipeline fluid delivery system, used to change the passage section and medium flow direction, with diversion, cut-off, throttle, check, shunt or overflow pressure relief and other functions. The valve used for fluid control, from the simplest stop valve to the most complex automatic control system used in a variety of valves, its varieties and specifications are wide, the nominal diameter of the valve from the very small instrument valve to the diameter of 10m industrial pipeline valve. It can be used to control the flow of water, steam, oil, gas, mud, various corrosive media, liquid metal and radioactive fluids and other types of fluids. The working pressure of the valve can be from 0.0013MPa to 1000MPa of ultra-high pressure, and the working temperature can be c-270℃ of ultra-low temperature to 1430℃ of high temperature.
