2) Only external seals for 10 valves
Description
Initially, flow passes freely from 2 to 1. When the pressure
at 1 exceeds the pressure setting, the valve acts to restrict
input flow at 2. This increases the pressure drop through
the valve and maintains consistent pressure at 1. The spring
chamber is drained at 3 to prevent a build-up of back-
pressure against the spool. Additionally, if pressure at 1
rises above the pressure setting, flow is relieved to 3 until
the setting is re-attained.
