ASCO 8320G704 Solenoid Valve

ASCO 8320G704 is a compact, direct-acting general-service solenoid valve designed for air and inert-gas control, featuring a brass body, 1/4" NPT ports, and a 3/2 normally closed (3/2 NC) configuration for reliable on/off control in tight spaces. Energizing the coil moves the internal mechanism to allow flow or redirect it, while de-energizing returns the valve to the closed position, making it suitable for isolating or diverting gas streams in instrumentation, automation, and process lines. This model is offered with dual coil voltage options—120/60 VAC or 110/50 VAC—and a coil wattage of about 10.1 W, enabling flexible integration with standard control systems; it is rated for inlet pressures up to 150 psi and has a flow coefficient (Cv) of 0.12, appropriate for small-diameter pneumatic circuits. The valve uses Buna-N (NBR) seals and brass construction for compatibility with clean compressed air and inert gases, with 1/4" NPT ports that suit common pneumatic fittings. For maintenance, it carries a valve order code of 21365, and compatible service parts include a replacement coil (238610-032-D) and a rebuild kit (318818). Typical applications include laboratory instrumentation, process automation, gas sampling, and other systems requiring precise, reliable, low-flow control of compressed air or inert gas.
