By combining various control pilots, multiple valve functions can be performed on a single Series 127 Pressure Reducing Valve. To find the combination function valve, select the desired features and then the model number.

This chart shows only a sample of those most often specified valves. Consult the factory for specific data on the model you selected.

Combination valves can often reduce or eliminate other equipment. Example: If the system requires a Pressure Reducing Valve and a Check Valve, the check feature can be added as a function of the PRV, Model 127-4.

HIGH PRESSURE / HP
When valve outlet pressure requires the model 2420 High Pressure Reducing pilot, an HP is added to the end of the model number. Example: Standard model 127-3 (outlet ranges from 5 - 300 psi) Model 127-3HP (outlet ranges 200-750 psi)

LOW FLOW BY-PASS / LF
Most valves listed in this guide can be equipped with an intregral Low Flow By-pass regulator, an LF is added to the end of the model number. Example: Model 127-3 with low flow by-pass is 127-3LF. Valve sizing is an important aspect in correct use of this feature.
