Pilot Pressure Regulator (PR)0 pages
PILOT PRESSURE REGULATOR
1/4" NPT
Inlet 400 Psig (27.6 Bar)
PR
Description
Generant Series PR, Pilot Pressure Regulators are balanced,
relieving regulators ideally suited for providing a reliable, constant
pilot pressure to a Pilot Operated / Dome Loaded regulator. The
balanced design allows for a consistent, regulated downstream
pressure regardless of fluctuations in inlet pressure. The relieving
function allows the regulator to vent when adjustments are made
without the need for bleeding pressure from the pilot circuit.
Materials of construction allow for compatibility with most gases.
The Series PR can be ordered Cleaned & Packaged for Oxygen
Service.
