A valve for directing pressurized fluid includes a fluid directional element for controlling fluid flow to a work member and a motor, and a one way flow member for controlling fluid flow to the work member. The one way flow member is actuated by a pilot operated actuator. The pilot operated actuator includes surfaces against which fluid pressure acts to move the actuator from a first position to a position actuating the one way flow member to allow flow to the work member. The valve further includes a capturing mechanism to hold the pilot operated actuator in its actuating position to hold the one way flow member in the actuated position allowing flow to and from the work member.
