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.

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
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 operation must take place first.
