ASCO 321 Series Solenoid Valves

Asco

The ASCO Series 321 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.
