PP check/non-return valves
A non-return valve ensures medium can only flow in one direction, ensuring that the fluid flows through a pipe in the right direction. We have non-return valves sizes ranging from 3/4" to 2" with a stainless-steel spring. This can take a maximum pressure of 1 bar. The seal material for the valve comes in EPDM (ethylene propylene diene monomer). Check valves are usually designed for a particular pressure.
