Pilot operated check valves. They are non modular valves, arranged for in line or flanged mounting.As the cartridge valves, they are made of 1 or 2 unidirectional check valves, in which pilot pressure opens the sealing poppet. A check valve, clack valve, non-return valve, reflux valve, retention valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body CHECK VALVES and PILOT CHECK VALVES General Information. Fluid:best use mineral oil with viscosity ranging between 10 and 200 cSt. Filter:dirty oil is the main reason for failure and troubles of hydraulic parts and systems.

A check valve is a type of valve which normally allows fluid (liquid or gas) to flow through it in one direction but not the opposite direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.
