CV12-20 Hydraulic cartridge check valve with 2 ports of checking system pressure, port 1 is inlet port and 2 port is for blocked off port when pressure flow backs. These CV12-20 hydraulic cartridge check valves are used for pressure keeping for a short time or avoid back pressure which will harm to main hydraulic components mounted in the same line.

Finotek CV12-20 hydraulic cartridge check valve is poppet design as inner sealing, this series of cartridge type check valve is for the requirements of large flow rate system with high pressure, the valve block is available to us as to installed the valve with standard cavity.
