Pilot operated, balanced piston sequence valve
SERIES 3 / CAPACITY: 240 L/min. / CAVITY: T-17A
Pilot-operated, balanced piston sequence valves will supply a secondary circuit with flow once the pressure at the
inlet (port 1) has exceeded the valve setting. The pressure setting of a sequence valve controls the pressure at port
1 relative to the pressure at the drain (port 3). These valves are insensitive to back pressure at port 2 (sequence),
up to the valve setting. They may be used to regulate pressure in place of 2-port relief valves if there is pressure in
the return line.
