Pressure reducing and relieving,

direct acting spool type

Common cavity, Size 10

VRPR-10A 04.95.04 - X - 85 - Z

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.
