A Range of 3/2 and 5/2 Manually Operated 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° to 180º C (-4° to 356º F)
  • 316L Stainless Steel Construction
  • Designed for Actuator Control
Pad Operated, Spring-Return with Pilot Latch:
 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 bar (7 psi) 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.

Pad Operated, Spring-Return with Pilot Latch and Visual Indicator:
The visual indicator will show RED when the valve is closed. If a pilot signal is applied the valve will not operate. When the valve is operated (via the pad) the pilot signal latches  the valve in the operated position and the visual indicator will show GREEN - on loss of the pilot signal the valve will reset and the visual indicator will show RED again - reintroduction of the pilot signal will not operate the valve.

Pad Operated, Spring-Return with Pilot Latch and Manual Latch Pin:
Manual Operation:

To operate the valve, pull out the pad, if the pad is released the valve will return to the un-operated position.

To leave valve operated press down the manual latch pin when pad is pulled out, then release the pad so that the manual latch pin engages. To return valve to its un-operated position, pull out the pad, this will dis-engage the manual latch pin, then release the pad.

Pilot Signal Operation:
To operate the valve, pull out the pad and apply a pilot pressure of between 3 to 10 bar to the signal port, the valve will remain operated until the pilot pressure is lost.
The valve cannot be operated by pilot pressure alone, pad must be pulled out first.

Releasing the Manual Latch with Pilot Signal:
If the valve has been manual operated and latched, this can be released by applying a pilot pressure to the signal port, this   will release the manual latch, so when pilot pressure is lost the valve will return to the un-operated position.

Pad Operated, Spring-Return with Pilot / Manual Latch Pin and Visual Indicator:
The visual indicator will show RED when the valve is closed. The valve is operated by pulling out the pad - the latch pin when pressed while releasing the pad will hold the valve in  the open position - the visual indicator will still show RED. When a pilot signal is applied the latch pin is released and    the visual indicator will show GREEN - on loss of the pilot signal the valve closes and the visual indicator will show RED - reintroduction of the pilot signal will not operate the valve.
