ASCO 320-S Series Solenoid Valve

Brand: ASCO

The ASCO Series 320, also known as 8320, are general service solenoid valves designed for a broad range of applications.

The direct-acting valves are available in voltage-ranging, harsh-environment, direct-mount, dribble-control, and long-life constructions.

They are suitable for use in analytical and diagnostic equipment, dust collector systems, life sciences, and press room and metal stamping.
  • All NPT connections are in the valve body to allow in-line piping
  • No minimum operating pressure differential required
  • Available in brass and stainless-steel constructions
  • Mountable in any position
  • Long-life version eliminates metal-to-metal contact to extend life up to 20 million cycles in dry air or gas applications. Easily handles rapid cycling or continuous energization
  • Harsh-environment model offers low power consumption plus quick shutdown of valves and actuators. Valves are UL, CSA, ATEX, and IIECEx certified
  • RedHat Next-Generation model offers voltage-ranging with low-power operation. Valves have Class I, Division 2 coils
