ASCO 310420-HW BULL 8221 AC Industrial Solenoid Valve

ASCO 310420-HW is a rebuild kit for the ASCO 8221 AC series solenoid valves, designed to refresh the coil/actuation assembly rather than replace the entire valve body. Specifically designed for 8221G007 normally closed valves, it provides parts to restore valve performance without full replacement. Contents include Cap, Clip, Core Tube Assembly, Flow Control, O-Rings, Piston Assembly, Seal, Springs, Support, and Tube, and it is marketed as the 8221 AC coil rebuild kit compatible with 8221G007. The 8221 family uses AC coil actuation with standard voltages such as 24, 120, 240, or 480 VAC at 60 Hz (and 50 Hz variants), with coil wattage in the 6.1/F class insulation range; for 50 Hz service, the wattage is about 8.1 W, informing drive circuitry and cooling needs. This kit is ideal for field maintenance of ASCO 8221 AC valves in industrial water, gas, or air service where reliability and minimal downtime are critical.
