ASCO 321 Series Quick-Exhaust Solenoid Valves

Brand: ASCO
The ASCO Series 321, also known as 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
  • 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
