In line check valves available from 1/8″ to 2″ bsp. Max. working pressure 400/320 Bar, oil flow rate up to 850 Lt./min ( depending on the size ). On request NPT THREADS can be supplied

They are inserted in branches of the circuit where the free flow in one direction is allowed and the return flow in the opposite direction is not possible. A lasting and hermetic seal is ensured by the conical valve poppet, which is a reliable mechanical solution. The spring in high-resistance material is housed in such a way that it does not close as a pack during the opening phase. The external configuration of the body makes it easy to seize the piece during the assembling. They are available with different cracking pressure (0,5 standard and 2-4-6-8-10 bars).
