Pad (To Pull) Spring Return with Pilot Latch and Visual Indicator

1500 Series Spool Valve, Pad Operated, Spring Return with Pilot Latch & Visual Indicator Midland ACS logo

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

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.
