Claim 0:
1. A hydraulic valve, comprising:
a body having an inlet and an outlet;
a motor supported by said body and operating a shaft extending through an interior of said body, said shaft terminating in a gate;
a spring supported within said housing and influencing said gate in an open position to permit fluid flow between the inlet and outlet;
upon occurrence of a pressure differential resulting from a fluid flow through the inlet exceeding a biasing force of said spring, said gate being 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; and
said motor operating in a throttling mode to linearly and incrementally displace said gate between the open and closed positions in order to adjust flow through the outlet.
