A hydraulic valve having a body defining an inlet and an outlet. A motor is supported by the body and operates a shaft extending through an interior of the body, the shaft terminating in a gate. A spring is supported within the housing and influences the gate in an open position to permit fluid flow between the inlet and outlet. Upon the occurrence of a pressure differential resulting from a fluid flow through the inlet exceeding a biasing force of the spring, the gate is caused to displace against a valve seat communicating the inlet with the outlet in order to interrupt fluid flow in a standby mode and to define a closed position. The motor operates in a further throttling mode to linearly and incrementally displace the gate between the open and closed positions said outlet and in order to adjust flow through the outlet.
