Apollo Valves A108 Pressure Relief/Sustaining

A108 Series Pressure Relief/Sustaining Description

The A108 Series Pressure Relief/Pressure Sustaining Automatic Control Valve has a wide range of applications: anywhere a system must be protected from pressures that are too high (relief) or too low (sustaining). The normally closed, spring-loaded pilot, sensing upstream pressure, responds to changes in pressure and causes the main valve to do the same.

The net result is a constant modulating action of the pilot and the main valve to hold the upstream pressure constant. The pilot system is equipped with a closing speed control that fine-tunes the valve response to the system variables. Proudly made in the USA.
