Hydraulic One-Way Throttle Cartridge Valves

Hydraulic Screw In One Way Check Valves

The DLF is a cartridge check valve. It will allow flow in one direction, and blocks flow in the opposite direction. It may also be referred to as a non-return valve. The valve uses sealed poppet technology to give virtually zero leakage with liquids and gases. In the check valve flow is free in one direction and blocked in the reverse one. Small dimensions and their insert configuration makes these valves ideal for installation into custom designed hydraulic integrated circuit.
