General Description
Direct Acting Sequence Valve
(Internally Piloted, Externally
Check
Valves
SH Drained). In the steady state
condition, all three ports are blocked
with the spring chamber drained to port 3.
When the pressure at port 1 exceeds the valve setting,
the spool moves allowing flow from the nose of the

cartridge (port 1) to the actuator port (port 2). By
externally draining the spring chamber directly to tank
(port 3), the valve is insensitive to back pressure at the
sequence port.
