VRPR-07A-S

RE18318-60-01(2023-11-24)
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. VRPR-07A-S is equipped with a damped type spool especially designed for demanding applications.

¹) 1 - 3 to 80% of pressure setting

²) Only external seals for 10 valves
