[ma0641]

Loosen the locknut and then slowly unscrew the stem. Make sure water is flowing so you can see the change. When satisfied, tighten the locknut.

[SIZE=2]the system down. Care should be taken not to open
the bypass completely to prevent the safety relief
valve (if installed) from popping off. After blowing down
the system, close the bypass valve.
2. Loosen the lock nut on the adjusting screw to allow
adjustment. Relieve the adjusting spring. See Figure
2-1.

small amount of fluid can pass.

Reducing Valve. Selection or installation of equipment should always be accompanied by competent technical
assistance. You are encouraged to contact Armstrong International, Inc. or its local sales representative for additional
information.

on liquid quality) should be installed before the PRV
to reduce the chance of dirt fouling.
2. Pressure gauges should be installed before and after
the PRV.
3. Piping a bypass line with a globe valve around the
PRV will allow system operation while the PRV is
being serviced. Install only if fluid cannot be shut-off
to service PRV.
4. Do not install quick opening or closing valves
downstream of PRV.
5. Install the PRV with the flow in the direction of the
arrow on the body.
Improper adjustment of the pressure reducing valve may cause hunting, improper control, and possible damage to the
valve itself. Adjust the valve as follows:
