PRESSURE REDUCING VALVE FINAL-LINE GAS SERVICE INSTALLATION INSTRUCTIONS
Before installation, these instructions must be carefully read and understood
DESCRIPTION
GENERAL INSTALLATION INSTRUCTIONS
The Type E-55 pressure reducing and
regulating valve is specifically designed for
use in the final-line circuit and maintains a
relatively constant pressure differential across
the valve even during high flow rates.
Type E-55 regulators should be installed in the
horizontal position with the spring chamber
upright. For other installation requirements,
consult the factory. For easy operation and
maintenance, it is suggested that manual
shut-off valves be installed upstream and
downstream from the valve and a pressure
gauge between the regulator and the

OPERATING INSTRUCTIONS
Adjusting the Delivery Pressure
The regulator’s delivery pressure setting is
adjusted by turning the adjusting screw (1) at
the top of the spring chamber after loosening
the adjusting screw lock nut (2). To increase
the delivery pressure, turn the adjusting
screw clockwise (into the spring chamber).
To decrease the delivery pressure, turn the
adjusting screw counter-clockwise (out of the
spring chamber). Tighten the adjusting screw
lock nut after the adjustment has been made.
Open a valve downstream to draw flow and
close to check setting after each adjustment.
MAINTENANCE INSTRUCTIONS
CAUTION
Before attempting to replace any spare parts, be
sure to shut off all pressure connections to the
valve. Before proceeding with any valve service, be
certain to relieve the pressure from both sides of
the regulator.
