Singer Valve - Model 106/206-PR -Pressure Reducing Valve
The 106-PR and 206-PR series pressure reducing valves are based on the 106-PG or 206-PG main valves. The pilot valves sense the downstream pressure through a connection at the valve outlet. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm. The downstream pressure is maintained virtually steady at the pilot set-point. In typical pressure reducing applications, the reduced port model 206-PR is often the best selection.
- Ideal for maintaining accurate downstream pressure
- Responds quickly and effectively
Note: The smaller PR valve by-passing the main valve helps control low flows and provides service during maintenance. It should be set 3 – 5 psi / 0.2 – 0.35 bar higher than the larger valve.
Singer Valve single rolling diaphragm technology 6 in / 150 mm and larger have extremely precise control, even at low flows, making smaller by-pass valves unnecessary except for possible bypass during maintenance.
