Pilot solenoid control valve with an emergency operator |
摘要 |
A discharge valve is provided to open an electrically controlled pilot valve in emergency situations such as during an electrical or hydraulic failure. The discharge valve has a poppet that operates in response to a pressurized control signal, which may be produced by a hand operated pump. When the poppet opens in response to the control signal, a path is established for fluid to flow from a control chamber of the pilot valve, thereby opening the latter valve.
