Pressure Reducing Valve
1. Standard Pressure Reducing Valve (106 / 206-PR)
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
2. Pressure Reducing Valve with Dual Adjustable Set-Point
(206-2PR-SC-BT)
Pressure Reducing Valve with Double Pilot Setting
Pressure Reducing Valve with two set points, high pressure and low pressure.
Time-based selection via latching solenoid and timer. Self-contained, powered by a 9-volt battery ( 1 controller and 1 programmer)
24/7 time settings (can skip days). Multiple time selection possible (up to 10 time setting per 24 hour period)
Reduces system pressure when not needed (low flow demand or night time), supplies increase pressure when required (high flow demand or day time)
Recommended for system where no external power source is available
3. Pressure Reducing Valve with Solenoid Shut-Off (106 / 206-PR-SC)
The 106-PR-SC and 206-PR-SC pressure reducing valves with solenoid shut-off are based on the 106-PG or 206-PG main valve.
The 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 relatively steady at the pilot set-point.
The solenoid shut-off / override interrupts the PR function to close off the main valve. The valve is available as either normally open where the solenoid is energized to close the main valve or as normally closed where the solenoid is de-energized to close the main valve.
- Excellent low flow stability
- Fast-acting solenoid override
- Operates as normally open or closed
- Easily and precisely set downstream pressure
4. Pressure Reducing Valve with Low Flow By-Pass (106 / 206-PR-48)
The 106-PR-48 and 206-PR-48 series pressure reducing valves with low flow by-pass are based on the 106-PG or 206-PG main valve. In addition, a direct acting pressure reducing valve is piped in parallel, using the main valve back port connections.
The pilot valve senses the downstream pressure through a connection at the main valve outlet. Under flowing conditions, the pilot reacts to small changes in pressure to control the main valve position by modulating the pressure above the diaphragm. The downstream pressure is maintained relatively steady at the pilot set-point.
The by-pass valve is set 5 psi / 0.35 bar higher than the main valve. Under low flow conditions, the main PR valve closes and the by-pass stays open, controlling the pressure at very low flows without seat chatter.
In typical pressure reducing applications, the reduced port Model 206-PR-48 is often the best selection.
- Maintains stable flow right down to zero
- Precise and reliable pressure setting
- By-pass piped in parallel to reduce space requirements
