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 (turn counterclockwise to increase

setting - turn clockwise to decrease 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. Any

back-pressure at 2 is additive to the pressure setting in all

functions.
