Metering Flow Control Valve CMF25

The CMF25 is a 1/4” nominal bore metering valve with a reverse free-flow check function. It provides metered flow in one direction, and free flow in the opposite direction, ideal for uni-directional speed control of a cylinder or actuator. The valve can be adjusted manually after installation, and the setting can be locked. Note that this is a flow control valve and is not intended to provide tight shut-off when closed.
