Model 106 / 206-PR
Pressure Reducing Valve
|
The valve shall maintain a constant downstream pressure with extreme accuracy, regardless of fluctuations in the upstream pressure or flow. |
| |
Model 106 / 206-PR-R
Pressure Reducing and Pressure Sustaining Valve
|
The valve shall maintain a constant (adjustable) downstream pressure with extreme accuracy, regardless of fluctuations in the upstream pressure or flow. A pressure sustaining function shall override the pressure reducing function should the upstream pressure fall below a pre-determined (adjustable) desired minimum value. |
| |
Model 106 / 206-PR-48
Pressure Reducing Valve with Low Flow By-Pass
|
The valve shall maintain a constant downstream pressure with extreme accuracy, regardless of fluctuations in the upstream pressure or flow. A direct acting, by-pass pressure reducing valve shall be integral to the pilot system and shall overlap the minimum flow capacity of the main valve to ensure stable operation down to 1 gpm. |
| |
Model 106 / 206-PR-C
Pressure Reducing and Check Valve
|
The valve shall maintain a constant downstream pressure with extreme accuracy, regardless of fluctuations in the upstream pressure or flow. The valve shall close drip tight to stop reverse flow if the downstream pressure exceeds the upstream pressure. |
| |
Model 106 / 206-PR-SC
Pressure Reducing Valve with Solenoid Shutoff
|
The valve shall maintain a constant downstream pressure with extreme accuracy, regardless of fluctuations in the upstream pressure or flow. The valve shall close drip tight when the solenoid pilot valve is de-energized-NORMALLY CLOSED (energized - NORMALLY OPEN). |
| |
106 / 206-PR-S
Pressure Reducing Valve with Downstream Surge Protection
|
The PR pilot valve senses 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 constant at the pilot set point (adjustable). The surge pilot senses the downstream pressure. If the pressure rises above the PR pilot setting and reaches the surge pilot setting, the surge pilot opens in order to close the main valve rapidly. |

106-PR-8702
ULC Labelled and Listed Pressure Reducing Valve
|
The Singer Model 106-PR-8702 and A106-PR-8702 pressure reducing valves employ the basic Singer model 106-PG or A106-PG main valve respectively. Pressure reducing valves (-PR) automatically reduce a higher inlet pressure to a constant, lower discharge pressure, regardless of fluctuations in flow or
inlet pressure. |
The primary function of the pressure reducing valve is to maintain a constant downstream pressure.
