Description
Zero differential overcenter
valves give static and dynamic
control of loads by supplying
a restriction to flow related
to the opening of the valve
created by the pilot pressure.
The valve is used in
conjunction with a remote
pilot source to provide hose
failure protection, load control
and load holding functions.
If over-pressure or shock
pressure protection is required
then a separate relief valve
should be used
The drain line allows the
valve to be used in corrosive
atmospheres preventing
the ingress of atmospheric
contaminant.
Operation
The check section allows free
flow into the actuator then
holds and locks the load against
movement. By the application
of pilot pressure to the pilot port
the poppet moves back against
the main spring opening the
cylinder port to the valve port.
The metering characteristic of
Performance Data
Sectional View
Pressure Drop
the valve is controlled by the rate
of the spring, the seat angle and
the pilot pressure applied.
Due to the balanced poppet
design load induced pressure
will not open the valve and once
open valve port pressure will
not increase the pilot pressure
required to keep the valve open
Features
The cartridge fits a simple
cavity allowing quick, easy
field service reducing down
time. Hardened poppet and
seat provide for long leak free
performance.
