When pressure at 3 rises above the spring bias pressure, the check seat is pushed
away from the piston and flow is allowed from 3 to 2. When load pressure at 2 rises
above the pressure setting, the direct-acting, relief function is activated and flow is
relieved from 2 to 3. With pilot pressure at 1, the pressure setting is reduced in
proportion to the stated ratio of the valve, until fully open with free-flow from 2 to 3.
The spring chamber is vented to atmosphere allowing operation of all functions
independent of back-pressure at 3.
