Patent ID: 8881759

Claim:
A selector ( 500 ) useful for controlling flow of fluid in a hydraulic control valve ( 1000 ), said flow of fluid controllable by an actuator ( 200 ) comprising a plunger ( 210 ), said actuator ( 200 ) having at least two states, a first state with said plunger ( 210 ) in a blocking position preventing flow of fluid past the tip of said plunger ( 210 ), and a second state with said plunger ( 210 ) in an unblocking position permitting flow of fluid past the tip of said plunger ( 210 ), said selector ( 500 ) comprising: a. a bore ( 540 ) characterized by a nozzle gate ( 542 ), said bore ( 540 ) blockable at said nozzle gate ( 542 ) by said plunger ( 210 ); and b. a manual control means ( 550 ) adapted to reversibly transition said selector ( 500 ) between at least two positions, a first at least one position ( 1030 ), and a second at least one position ( 1040 , 1050 ) in which fluid flow bypasses said plunger ( 210 ) tip, enabling manual control of said fluid flow, wherein said hydraulic control valve ( 1000 ) is adapted to provide, in said at least one first position, fully-automatic control ( 1030 ) by enabling fluid flow past said tip of said plunger ( 210 ) so that said states of said actuator ( 200 ) control fluid flow and, in said at least one second position, fully-manual control of water flow by either (a) blocking fluid flow through said selector ( 1050 ), thereby preventing fluid flow through said valve or (b) providing a fluid connection through said selector ( 1040 ) wherein fluid flow is via a fluid connection ( 520 , 525 ) bypassing said nozzle gate ( 542 ) of said bore ( 540 ), thereby enabling fluid flow through said hydraulic control valve ( 1000 ) independent of the position of said plunger ( 210 ), and wherein said bore ( 540 ) is characterized by a main longitudinal axis and said manual control means ( 550 ) is adapted to rotate said selector ( 500 ) about said bore ( 540 ) main longitudinal axis.
