SXCB
Atmospherically referenced, direct-acting sequence valve without reverse flow
check
SERIES 1 / CAPACITY: 60 L/min. / CAVITY: T-13A
Atmospherically referenced, direct-acting 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 this sequence valve controls
the pressure at port 1 relative to the atmospheric vent.

TECHNICAL FEATURES
Suitable for use in load holding applications.
Atmospherically referenced valves should only be used where it is impossible have a drain connection. Over time, the atmospherically referenced valves may leak
externally or allow moisture into the spring chamber.
Approximately 1 drop (0,07 cc) of fluid will pass into the vented spring chamber every 4000 cycles.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
