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, 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, and any back-pressure at 2 is
additive to the pressure setting in all functions.
