Pressure setting: at least 1.3 times the load induced pressure.
1) At 70% of pressure setting
2) Only external seals for 10 valves
Description
When pressure at 2 rises above the spring bias pressure,
the check seat is pushed away from the piston and flow is
allowed from 2 to 1. When load pressure at 1 rises above
the pressure setting, the direct-acting, differential area
relief function is activated and flow is relieved from 1 to 2.
With pilot pressure at 3, the pressure setting is reduced in
proportion to the stated ratio of the valve, until fully open
with free-flow from 1 to 2. The spring chamber is drained to
2. The valve applies a balanced piston design allowing relief
operation at the valve setting independent of back-pressure
at 2. However, the piloted opening of the valve remains
subject to additive pressure at port 2.
