0−900 psi Pressure Reducing
Diaphragm Regulator
Description
The Nordson 0−900 psi diaphragm regulator
reduces high primary pressures to lower secondary
pressures. It is a non-venting regulator designed
for use in systems with low fluid flow rates.
Installation
WARNING: Allow only qualified personnel
to perform the following tasks. Follow the
safety instructions in this document and all
other related documentation.
1. Refer to Specifications for mounting and panel
cutout dimensions.
2. Install fluid lines with 3/8-in. NPT fittings in the
IN and OUT fluid ports.
Repair
WARNING: System may be pressurized.
Relieve pressures. Failure to observe this
warning may result in serious injury or
death.
Repair is limited to replacing the parts included in
the service kits. See Repair Kits for available
repair parts and kits.
The fluid regulator diaphragm service kit listed in
Repair Kits upgrades old style regulators to prevent
paint from spraying out of the regulator if the
diaphragm fails.
Diaphragm Replacement

1. Remove the cap (1), nut (2), and knob (3).
Remove the regulator from the panel or
bracket.
2. Remove the bonnet ring (4), washer (7),

diaphragm button, and tighten to
10.7−11.3 NSm (95−100 in-lbs).
b. New style regulators (Fig. 2): Install the
sensor (24) on the diaphragm button, and
tighten to 10.7−11.3 NSm (95−100 in-lbs).
5. Place the diaphragm assembly in the body.
Install the spring pad and spring on the
diaphragm assembly.
6. Install the bonnet, washer, and bonnet ring.
Tighten the bonnet ring to 169.4−176.2 NSm
(125−130 ft.-lb). Wait a minimum of 1 hour,
