317 Series Brass, 1/4" NC, Air Only, 3-Way Quick Exhaust Solenoid Valve
The ASCO Series 317 and 321, also known as 8317 and 8321, quick-exhaust solenoid valves are designed for quick venting to 0 psi through their external orifice. Air is exhausted to rapidly shift control valves. The pilot-operated valves have resilient seated poppets for tight shutoff. They are well suited for refining, chemical, and food and beverage applications that require a quick-exhaust valve.
Features
- NC (Closed when de-energized), Air Only - Vents to Atmosphere
- Valves are available in voltage-ranging and harsh-environment constructions
- Next Gen solenoid models available that reduce power consumption, increase AC and DC operating temperatures, and extend coil life
- Mountable in any position for flexible installation
- ATEX, IECEx certifications for operation in hazardous conditions
