Pressure Sustaining Pilot Valve #3PB

This is a direct acting pilot valve, actuated by a pressure responsive
diaphragm, which tends to reach equilibrium with the set spring force.
When used in a pressure relief/sustaining circuit, the pilot modulates open
as upstream pressure rises above set point.

■ Internal or external pressure sensing
■ Differential pressure sensing
■ Direct pressure gauge installation

■ Pressure relief/sustaining valve sizes 11/2-4”
(Standard model #3PB).
■ Differential Pressure sustaining valve sizes 11/2-4”
(Modified to differential sensing #3PB-D)
