Corrosion Resistant, Explosion Proof Solenoid Operator for ASCO? Series 327 Low Power Valves with UL, CSA, ATEX and IECEx Approvals

ASCO 327 Series valves

The ASCO Series 327 low power?valves are now available with a corrosion resistant, explosion-proof solenoid operator (prefix EV), which features a 316 stainless steel conduit hub and stainless steel baseplate for superior corrosion resistance.?

The Series 327 low power valves are designed for high flow piloting with no minimum operation pressure required. They provide energy-savings and are ideal for use in plant control systems and remote applications, providing PLC and DCS compatibility for BUS networks and traditional wiring. Special rider rings reduce friction and eliminate sticking to provide exceptional service life.

Key Features & Benefits
The new corrosion-resistant solenoid operator features:

  • Global approvals: UL, CSA, ATEX, IECEx approved solenoid for use in hazardous locations
  • Class F or Class H insulation
  • New options: surge suppression and battery charging ?

Segments & Applications
Key industries for the Series 327 low power valves include:

  • Oil and gas
  • Refining
  • Chemical and petrochemical
