How many types of check valves do you have?
We have Lift Check Valve,Vertical lift check valve,Swing check valve and so on.
Lift Check Valves are suitable for small-diameter pipelines, water, oil and air systems with sensitive reaction.
Vertical lift check valves are installed on vertical pipelines, pump stations and clean medium pipelines with good sealing performance.
Swing check valves are widely used for large-diameter main pipelines, steam, fire fighting, sewage and industrial pipelines.
How does a check valve work?
Check valves operate automatically. They only allow medium to flow forward and immediately prevent backflow.
Lift check valves open and close by lifting the disc up and down.
Vertical lift check valves are specially designed for vertical pipelines and work by vertical lifting movement.
Swing check valves open and close through automatic swinging of the disc.
Application scenarios of check valves
Lift check valves are suitable for small-diameter pipelines, clean water, oil, gas and compressed air lines. They feature sensitive response and easy installation, applicable to vertical & horizontal small-bore pipes.
Vertical lift check valves are used for vertical risers, pump inlet & outlet pipelines and medium-pressure clean pipelines. They have excellent sealing performance and smooth flow passages, mostly applied to vertical pipelines in pump stations.
Swing check valves are applied to large-diameter main pipelines, steam, sewage, impurity-containing media, fire fighting main lines and municipal water supply systems. They have low flow resistance and high pressure difference resistance.
What is the difference between a check valve and a non-return valve?
There is no actual difference between a check valve and a non-return valve.
They are exactly the same product.
Check valve is the American English term.
Non-return valve is the British English term.
