Midland-ACS 3/2 pad (to pull) spring return with pilot latch spool valves in stainless steel for use on gases.

Features and Benefits:

  • Specifically designed for severe environments
  • 3/2 and 5/2 versions
  • Ambient temperature range -20 ºC to +180 ºC
  • 316L stainless steel construction
  • Designed for actuator control
  • NACE option available

Working Temperature Range:

  • Valve only version -20 ºC to +180 ºC (-4 ºF to +356 ºF)
  • Low temperature version -50 ºC (-58 ºF ) (optional)

Working Pressure:

  • 12 bar (174 psi) maximum

If a pilot pressure of 1.5 to 10 Bar (21 to 145 psi) is present at pilot ports when the knob is pulled out, the pilot pressure will hold the valve in the operated position against the return spring. If the pilot pressure falls to 0.5 (7psi) or less the valve will be reset to its unoperated position. The valve cannot be operated by pilot pressure alone, manual operation must take place first.
