  • Pilot actuated control pilot for operating valve
    Patent number: 10711915
    Abstract: A pulse valve assembly including a main valve and two pilot valves. The main valve includes a main valve body, main valve bore, and main valve spool. The main valve body includes an inlet port, an outlet port, and a pressure chamber at one end of the main valve bore. A first pilot valve selectively supplies pressurized fluid to the second pilot valve depending on the position of a poppet, which is controlled by a solenoid. A second pilot valve includes a spool that is driven by pressurized fluid from the first pilot valve. The second pilot valve selectively supplies pressurized fluid to the pressure chamber in the main valve causing the main valve spool to move towards the open or closed position. When the main valve spool is in the open position, pressurized fluid can flow through the main valve from the inlet port to the outlet port.
