These valves are adjustable, non-compensated flow restrictors. An integral check valve around the regulating orifice allows free flow in one direction and metered flow in the other. Control is available in A only, B only, and A and B ports as an X type (meter–in) or Y type (meter-out). The P port is available only in the X type (meter-in) and does not contain a reverse flow check. The valve flow setting is adjustable by means of either a hex key adjusting screw and locknut, a hand-adjust knob, or a micrometer knob with keylock. A normal or fine metering capability is available.
