A filter screen is mounted to the underside of the diaphragm assembly to prevent debris from clogging the metering orifice, clogging the small passages of the pilot valve, or fouling the solenoid. A solenoid actuated pilot valve is operatively coupled to the upper pressure control chamber for venting pressurized water therefrom to permit the diaphragm assembly to move upwardly to open the valve. Pressurized water from a lower inlet chamber of the valve travels through a small metering orifice in the center of the diaphragm assembly to an upper pressure control chamber above a flexible membrane of the diaphragm assembly. A primary valve seat inside the housing is engaged and disengaged by a seal on the underside of the diaphragm to open and close the valve by connecting and disconnecting its inlet and outlet passages. 7202 Centennial Sta, Warminster, PA 18974ġ467 N Van Dorn St #C, Alexandria, VA 22304ģ460 Powells Crossing Ct, Woodbridge, VA 22193ĥ07 Park Place Ave, Bradley Beach, NJ 07720ĥ01 N Ramblin Oaks Dr, Oklahoma City, OK 73160Ĥ69 Stonemarker Rd, Mooresville, NC 28117Ĥ606 Gunther St, Capitol Heights, MD 20743Ĥ873 Blossom Way APT 42, Grove City, OH 43123ĩ298 Dielman Industrial Dr, Saint Louis, MO 63132ĥ04 N Us Highway 69, Whitewright, TX 75491ģ654 Glenwood Ave, Redwood City, CA 94062Ĥ15 Hammertown Rd, Upper Stepney, CT 06468Ī diaphragm-type control valve for irrigation systems has an outer clam-shell housing that encloses a vertically reciprocable diaphragm assembly.
