RELIEF VALVE WITH FREE

PILOT OPERATED, POPPET TYPE
■ High flow capacity.
■ Virtually leak free, can be used for load holding applications.
■ Compact space saving design.
■ Integral 250 micron pilot flow filter.
■ Hardened working parts for maximum durability.
■ Adjustable and tamperproof versions available.
OPERATION
In one direction, the adjustable spring-loaded ball in the pilot section
is shifted at valve setting by pressure sensed through an orifice in
the main poppet from port [2]. The resulting pilot flow creates a
pressure drop across the spring-loaded main poppet that then opens
allowing relief flow to port [1]. In the reverse direction, a spring-
loaded check poppet sleeve is opened at low pressure on port [1]
allowing free-flow to port [2].
