How to turn water pressure down in house what direction do I turn pressure valve

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.

1. Close the gate valves before and after the PRV. Open
the bypass valve
slowly in the bypass line and blow
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.
3.
Slowly open the inlet side gate valve to the fully open
position, and partially open the outlet valve so only a
small amount of fluid can pass.
This bulletin should be used by experienced personnel as a guide to the installation of the Model GD-24 Pressure
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.
1. An Armstrong ìYî strainer (20 ñ 100 mesh, depending
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:
4.
Slowly turn the adjusting screw clockwise until the
desired pressure is obtained on the downstream
pressure gauge.
5.
Slowly open the outlet valve to the fully open position.
6. Adjust pressure again after system stabilizes.

decreases pressure.
7. Tighten the adjusting screw lock nut after adjustme
