A pilot valve adapted for connection between a double acting fluid actuator (12) of the piston-type and a hydraulic fluid supply (21). The pilot valve comprises an elongate body (30) with an axial bore (32, 33) therethrough and a piston chamber (38) at one end of the valve body. A valve plunger (49) affixed to the piston (50) in the piston chamber (38) is mounted in the axial bore for movement between first and second operating positions in response to the selective application of pneumatic pressure to the piston (50). The valve (20) is provided with val...
A pilot valve adapted for connection between a hydraulic fluid supply and a double acting fluid actuator of the hydraulic piston type, said pilot valve comprising: a generally cylindrical valve body having an axial bore extending therethrough and a piston chamber housing affixed to one end of said valve body in fluid communication with the axial bore; a valve plunger element slidably mounted in said axial bore for movement between first and second operating positions; a piston disposed in said piston chamber housing and affixed to one end of the valve pl...
