Model GD-24Pressure Reducing ValveInstallation, Operation andMaintenance Instructions*Illegal for potable water service per SDWA Section 1417 (as amended). Installation Instructions 1. An Armstrong “Y” strainer (20 – 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. Startup and Adjustment Procedures Improper adjustment of the pressure reducing valve may cause hunting, improper control, and possible damage to the valve itself. Adjust the valve as follows: 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. 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. Turning the adjusting screw; Clockwise increases pressure and Counterclockwise decreases pressure. 7. Tighten the adjusting screw lock nut after adjustment is completed.
