Role and purpose

(1) cut off type: such as gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves and so on.

Block valves, also known as closed-circuit valve, globe valve, whose role is to connect or cut off the pipeline of the medium.

Check valves, also known as the check valve or check valve, non-return valve is an automatic valve, its role is to prevent the pipe from the media back, prevent pump and motor reverse, medium and container leaks. Pump suction water shut valve is also a check valve at the end of class.

Explosion-proof valve, valve, safety valve is to prevent pipeline or pressure device in the media more than the regulation value, so as to achieve the goal of security.

Control valves, throttle valves and pressure reducing valves, its role is to regulate media parameters such as pressure, flow.

(2) vacuum: vacuum ball valves, vacuum block valve, vacuum valves, pneumatic valves, etc. Its role is in the vacuum system, used to change the direction of air flow, adjust the gas flow rate, cut off or put through the vacuum piping system components called the vacuum valve.

(3) special-purpose categories: such as a pig valve, vent valve, sewage valve, exhaust valve, filter, etc.

Exhaust valve in the piping system indispensable auxiliary components, are widely used in boilers, air conditioners, oil and gas, water supply and drainage pipes. Often mounted on high ground or at the elbow, eliminate excess gas in the pipeline and enhance road use efficiency and reduce energy consumption.
