General Description
Direct Acting Sequence Valve
(Internally Piloted, Externally
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.
Features
•
Hardened, precision ground parts for durability
•
Internal mechanical stop limits spool travel eliminating
spring solidification
•
“D”-Ring eliminates backup rings
•
All external parts have yellow zinc dichromate. This
coating is ideal for salt spray applications.
•
Fast response
