FAQ:
Q: What's the function of check valve?
A check valve is a device that only allows the flow of fluids in one direction. They have two ports, one as an inlet for the media and one as the output for the media. Since they only allow media flow in one direction, they are commonly referred to as 'one way valves' or 'non return valves.' The main purpose of a check valve is to prevent backflow in the system.
Q: Can I have a sample order?
Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.
