ASCO Introduces Harsh Environment Valves

FLORHAM PARK, NEW JERSEY, USA, May 19, 2011 – ASCO Numatics, the world’s leading manufacturer of comprehensive fluid automation, flow control, and pneumatics solutions, has introduced a new and improved line of ASCO Harsh Environment Valves. This series is designed for use in harsh and hazardous locations, including control panels in offshore applications such as oil platforms where the environment is extremely hot, humid, and corrosive. The new solenoid valve series is also ideal for use with solar panels and PLC/DCS applications where low power consumption is required. The New Harsh Environment valves are made out of 316L Stainless Steel material for maximum corrosion resistance and are available with 0.55 or 1.30 watt coils, as well as high flow and quick exhaust constructions, with pressure ratings ranging from 0 to 150 PSI.

Same dependability with lower power consumption: 0.55 & 1.3 watt constructions:

  • Up to 35% lower power consumption
  • Low power DC for solar panels
  • PLC compatibility
  • Reduced wiring cost
  • Reduced temperature rise
  • Increased battery life
  • Energy savings

More agency approvals and certifications- Designed for harsh and hazardous environments per UL, CSA, ATEX/IECEx requirements:

  • UL & CSA Approved for Class I Div. 1, Groups C & D; Class I Div. 2, Groups C & D
  • Types:1,2,3,4,4x,6, 6P,7
  • ATEX/IECEx: II 2 G Ex d IIB T6 Gb
  • CSA, ATEX, and IECEX approved with factory seal leads
  • SIL 3 capable per IEC 61508, third party certification provided by Exida
  • One valve meets all approvals: UL CSA, ATEX/IECEx

 Additional features include:

  • Increased corrosion resistance: 316L Stainless Steel Body, 316 Stainless Steel Externals
  • Up to 9% higher pressure ratings on low power constructions when compared to competition
  • High flow constructions with a 1.1 Cv pressure port and 1.4 Cv exhaust port for larger valves and actuators
  • Quick exhaust constructions with a 1.4 Cv exhaust port for fast shut-down of valves and actuators

 Ease of Replacement

  • Minimal changes to footprint

Improved Availability

  • Select constructions are available through the ASCO Express program
