发明名称 PILOT SOLENOID CONTROL VALVE WITH AN EMERGENCY OPERATOR
摘要 A discharge valve (150) is provided to open an electrically controlled pilot valve (100) in emergency situations such as during an electrical or hydraulic failure. The discharge valve has a poppet (154) that operates in response to a pressurized control signal, which may be produced by a hand operated pump (154). When the poppet opens in response to the control signal, a path is established for fluid to flow from a control chamber (118) of the pilot valve, thereby opening the latter valve.
