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