  • Pilot operated water conservation valve and actuator
    Patent number: 6748970
    Abstract: A fluid diaphragm valve and interconnected pilot valve apparatus for control flow of fluid discharge from a pressurized fluid distribution system. The apparatus has a primary valve with an inlet adapted to receive fluid under pressure, and an outlet adapted to discharge fluid to an outlet conduit. A diaphragm chamber is provided in the primary valve that is responsive to fluid pressure controlled by a pilot diaphragm valve. Upon release of fluid pressure in the pilot diaphragm valve, the primary valve allows passage of fluid to the outlet conduit. Bleed fluid from the pilot valve is also discharged into the outlet conduit and is thus saved for use. Upon closure of the pilot valve, a bleed port in the primary diaphragm in the primary valve allows repressurization and seating of the primary diaphragm, thus terminating fluid flow through the primary valve.
