Technical Feature
OPERATION
The 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 inlet (port ① ) relative to the pressure at the drain (port ③ ).
These valves are insensitive to back pressure at port ② , 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. -
