1500 Series Spool Valve, Pad Operated, Spring Return with Pilot and Manual Latch Midland ACS logo

Midland-ACS 3/2 pad (to pull) spring return with pilot and manual 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. Alternatively the valve can be mechanically latched in this position if no pilot signal is present. When a pilot signal of 2 to 10 bar (29 to 145 psi) is applied this will simultaneously allow the latch to release whilst holding the valve in the operated position the valve will reset to its unoperated position. The valve cannot be operated by pilot pressure alone, manual.
