MODELS 4VPS, 4VPD & 4VBL PILOT
SINGLE AIR PILOT|
MODEL 4VPS FOR SINGLE VALVE
A continuous pilot pressure applied to the valve will hold it in its shifted position. When the pilot pressure is released the valve will shift to its original position. Pilot pressure must be at least 25% of the operating pressure. Minimum operating pressure is 30 P.S.I
DOUBLE AIR PILOT|
MODEL 4VPD FOR SINGLE VALVE
A momentary or maintained pilot pressure applied to one side of the valve will cause it to shift. It will remain in that position until a pilot pressure is applied to the other side, which will cause the valve to return to its original position. If a maintained pilot pressure is employed, it must be released before the other pilot pressure is applied. Pilot pressure must be at least 25% of the operating pressure.
DOUBLE BLEED PILOT|
MODEL 4VBL FOR SINGLE VALVE
A separate Bleeder Valve, such as the Allenair BV100 or BV-1/8, must be installed in a line to each bleed port. Depressing one Bleeder Valve Momentarily will shift the valve. It will remain in that position until the other Bleeder Valve is depressed, which will cause the valve to shift to its original position.
Group mounting is a convenient method of mounting two or more valves using a single common inlet port. One or any combination of valves can be used on this group mounting.
