VALVE OPERATION
Both solenoids must be energized simultaneously to shift the
valve; maintained signal required to keep valve shifted.
WARNING: If monitor must be reset, electrical signals to both
solenoids must be removed to prevent the machine controlled
by the valve from immediately recycling and producing a
potentially hazardous condition.
OPTIONS
Valve Without Piping Flanges: See above.
Valve Without Silencer: Exhaust port has threaded flange only.
Consult ROSS.
Valve Response Time (msec) = M + F • V
See page 18 for response time values.
