ASCO NP8316A75V Solenoid Valve

ASCO NP8316A75V Nuclear Qualified Solenoid Valve is a high-flow, three-way valve from ASCO's NP8316 family, designed for instrument-air and nuclear-service applications. It features 3/4-inch ANPT porting and a 110–120 VAC, 50/60 Hz coil, enabling direct connection to standard power and piping. The valve body is brass, with a 305 stainless-steel core tube, and seals/discs offered in EPDM with optional FKMs for chemical resistance in nuclear systems; components in contact with the media include a brass body, 305 stainless steel core tube, and 430F stainless steel for the core and plugnut, with a copper shading coil in the solenoid. The NP8316 series is designed for mounting in any orientation and is suitable for directing flow to actuators or piloting larger valves in safety-critical pneumatic circuits. In nuclear contexts, these valves are qualified to IEEE nuclear-safety standards, ensuring reliability in demanding environments and making them a staple for oil-free instrument-air and related high-purity gas services in the nuclear industry.
