Additional Product Information

Valve function and use
(1) Cut-off categories: gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves, etc. Truncated valves, also known as closed-circuit valves and globe valves, act to switch on or cut off the medium in the pipeline.
Check valve, check valve, also known as check valve or check valve, check valve is an automatic valve, its role is to prevent the back flow of the medium in the pipeline, to prevent the reverse rotation of the pump and the drive motor, and the leakage of the container medium . The bottom valve of the pump is also a check valve.
Explosion-proof valve, accident valve, etc. The role of the safety valve is to prevent the medium pressure in the pipeline or device from exceeding the specified value, so as to achieve the purpose of safety protection.
Regulating valve, throttle valve and pressure reducing valve, its role is to adjust the pressure, flow and other parameters of the medium.
(2) Vacuum: vacuum ball valve, vacuum flapper valve, vacuum inflation valve, pneumatic vacuum valve, etc. Its role is in the vacuum system, used to change the direction of the air flow, adjust the size of the air flow, cut off or connect the vacuum system components called the vacuum valve.
(3) Special-purpose categories: such as pigging valves, vent valves, drain valves, exhaust valves, filters, etc. The exhaust valve is an essential auxiliary component in the pipeline system and is widely used in boilers, air conditioners, oil and gas, and water supply and drainage pipelines. It is often installed at high points or elbows, eliminates excess gas in pipelines, improves the efficiency of pipeline usage, and reduces energy consumption.
