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.

106 / 206-PR-48 Pressure Reducing Valve with Low Flow By-Pass

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.

106 / 206-F-Type 4 Modulating Float Valve

The Singer model 106-F-Type 4 and 206-F-Type 4 modulating float valves are based on the 106-PG or 206-PG main valve.They are ideal for balancing the inflow and outflow demand into the reservoir and maintaining level at the designated maximum.

The valve closes drip-tight at the maximum level and modulates to maintain the tank level. The float pilot is remotely installed at the high level in the reservoir tank. Pilot connections to the main valve are connected in the field. As the reservoir level drops the main valve is opened proportionally to increase the filling rate. Movement of the main stem alters the size of the closing restriction, interrupting the tendency of the valve to hunt.

106 / 206-PG-BPC Booster Pump Control Valve – Single Chamber

The 106-PG-BPC or 206-PG-BPC booster pump control valve is installed in-line directly downstream of the pump discharge.

The valve is normally closed, and, on pump start-up, a pilot solenoid is energized to slowly open the valve, at a rate governed by the opening speed control. The pipeline flow is gradually increased.

When shut-down is required, the pilot solenoid is de-energized to close the main valve and reduce the flow. The pump is kept running while the booster pump control valve slowly closes. When the valve is almost fully closed and flow is virtually stopped, a cam triggers the limit switch to stop the pump.

With the internal drop check option, the built-in mechanical drop check closes immediately when the flow stops, regardless of the valve position. Whether due to a control malfunction, normal operation or a pump motor power failure, by closing before flow reverses, surges are minimized.

The single chamber construction facilitates supplemental modulating functions such as pressure sustaining, pressure reducing, rate of flow control. Being a single chamber design, the control forces are generated by the differential across the valve. When a modulating function is included there are more positive initial closing results.

Substantially reduces pump starting and stopping surges

106 / 206-HC Hydraulic Check Valve

The 106-HC and 206-HC hydraulic check valves are based on the 106-PG or 206-PG main valve. The valve functions as a two position valve - either fully open or fully closed.

The HC allows one way flow only. Under normal forward flow, the valve opens as the higher inlet pressure lifts the inner valve assembly and the fluid in the upper chamber is discharged to the lower pressure, downstream side of the valve.

When pressure is reversed, the now higher downstream pressure is applied to the upper operating chamber as flow reversal occurs. The diaphragm / inner valve assembly moves down and the valve closes tightly.

The 106-A-Type 2 and 206-A-Type 2 altitude control valves are based on the 106-PG or 206-PG main valve and are ideal for maintaining a preset maximum water level.

The valve functions as a two position control valve, either fully open or fully closed. The Type 2 valve allows normal forward flow to fill the reservoir to the maximum level and then closes drip-tight at the set-point. It opens to refill the tank once the level drops a fixed distance below the high water level.

Note: This valve does not operate as a check valve to prevent reverse flow.

106 / 206-RPS-L&H Surge Anticipating Relief Valve

The 106-RPS-L&H and 206-RPS-L&H anticipating surge relief valves are based on the 106-PG or 206-PG main valve.

The valve is mounted in a tee, downstream of the pump check valve(s). It is designed to anticipate surges to avoid the severe water hammer often associated with power failure surges.

The RPS-L&H pilot system is comprised of two pilots, the 81-RP and the 82-PR. Both pilots sense pressure through a connection to the header pipe. The 81-RP high pressure pilot opens the valve to relieve excess pressure. The model 82-PR low pressure pilot opens quickly on below normal pressures prior to the return of a surge wave, initiating the opening of the main valve in anticipation of the high pressure wave’s arrival.

106 / 206-RPS-RR Surge Anticipating on Rate of Rise of Pressure Relief Valve

The 106-RPS-RR and 206-RPS-RR surge anticipating relief on rate of rise valves are based on the 106-PG or 206-PG main valve.

The valve is installed downstream of the pump check valve(s) and has two pilots, the 81-RP and the 81-RPD. Both pilots sense pressure through a connection to the header pipe. The 81-RP high pressure pilot acts as a standard relief pilot, opening on excessive pressure. The 81-RPD differential pilot responds to the pressure differential across its diaphragm. A pressure differential is created when there is a system pressure increase. The flow into the accumulator creates a pressure drop across the fixed restriction, which lowers the pressure in the connection between the fixed restriction and the pilot.

The pilot senses the pressure difference between this lower pressure and the header pressure. This difference occurs at the initiation of the pressure surge, providing the time necessary for the valve to open in anticipation of the high pressure.

A106-DL Dynamic Lifter Spring Pressure Relief Valve

The A106-Dynamic Lifter (DL) sewage pressure relief valve is a direct acting spring loaded relief valve.

The valve is adjusted to open when the pressure exceeds the set-point, which is approximately 10% above the normal operating pressure. The valve closes drip-tight when pressure falls below the set-point. The DL is connected on a tee off the main line and usually discharges relief flow back to the main sump to reduce the surge over-pressure. A speed control permits adjustment of the closing speed.

The opening force is boosted by the line pressure operating, via the separation chamber, on the piston. By applying external pressure to the test connection, the valve may be cycled open for routine maintenance.

Ideal for:

raw water that contains organics
lower pressure sewage lift stations
booster sewage stations
Low maintenance
Hygienic and minimal time to flush and test operations
Premium materials reduce maintenance, providing the lowest long-term cost of ownership

106 / 206-DW Deep Well Pump Control Valve – Double Chamber

The 106-DW and 206-DW deep well pump control valves are installed in a tee between the pump discharge and the check valve.

The valve is normally open, and, on pump start-up, a pilot solenoid is energized to start closing the valve at a rate governed by the closing speed control.

Initially, the valve discharges air, water and sand to waste. The open valve discharges all pump flow. As the valve closes slowly, flow is transferred to the main line smoothly, increasing the pipeline flow without surges. When the valve is fully closed, all pump flow is in the pipeline, with no control valve losses.

When shut-down is required, the pilot solenoid on the valve is de-energized to commence opening. The pump is kept running while the valve slowly opens. Increasing proportion of the flow is diverted to waste with less passing through the check valve, until all flow is diverted through the nearly fully open DW valve. The pipeline check valve closes quietly without surges. When the DW valve is almost fully open, a stem mounted cam triggers the limit switch to stop the pump.

106 / 206-EF-8837BX Excess Flow (Burst Control) Valve

TThe 106-EF-8837BX and 206-EF-8837BX excess flow valves are based on the 106-PT and 206-PT Double Chamber main valves. The valve is designed to shut-off tightly when flow exceeds a predetermined amount.

The 625-RPD pilot senses the pressure drop of the valve and closes the valve when the tripping flow is reached. Typical pressure drop at tripping is 5 psi / 0.35 bar.

Tripping flow is adjusted by limiting the valve opening with the X102 Stroke Limiter. 10 psi / 0.7 bar inlet pressure must be maintained at the valve inlet when the valve has tripped to prevent self re-setting. This valve closes fast and from a significant velocity. If the upstream pipe is longer than 2,000 ft /600 m, closing speed control should be included. When tripped (closed), this valve has a continuous exhaust of about 1 GPM / 0.063 L/sec to drain.

106 / 206-RF Flow Limiting Control Valve

The 106-RF and 206-RF Flow Limiting Control Valve are based on the 106-PG or 206-PG main valves.

The valve is ideal for limiting the flow to a pre-determined maximum (via maintaining a continuous pressure differential across an orifice). When the pressure differential is less than the set-point, the valve opens, allowing flow to meet predetermined demand. At the desired maximum set-point, the pilot reacts to small changes in sensing pressure and controls the main valve position by modulating the pressure above the diaphragm.

When the pressure drop across the orifice exceeds the set-point, the valve closes slightly, limiting the flow to the pre-set maximum. The orifice is usually sized to generate a pressure differential of 3 to 5 psi / 0.2 to 0.35 bar at the desired flow. Adjusting the pilot setting permits the maximum flow to be changed in the field above or below the original point.

106 / 206-PR-SM Pressure Reducing Control Valve with Integral

The 106-PR-SM and 206-PR-SM series control valves are engineered to be used anywhere pressure reducing valve failure is unacceptable. These valves have a second and independent operating system superimposed upon the standard primary system. With the assurance of a back-up system, maintenance schedules may be extended as pressures will continue to be controlled even in the event of failure with the primary system.

Under normal pressure reducing conditions, the primary pilot 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 in the lower operating chamber. The downstream pressure is maintained virtually steady at the pilot set-point that is adjustable.

Should the primary pilot system and / or main valve fail to control the downstream pressure, the independent back-up pilot system will begin to operate. It controls the pressure above the diaphragm in the second operating chamber. The back-up pilot is set slightly higher than the primary pilot. The forces now operating in the top chamber assume control of the inner valve assembly and maintain pressure reducing control. During back-up operation only, there is a small (1 USGPM / 0.063 L/s) continuous discharge that should be taken to drain.

The secondary pilot continually senses the downstream pressure. Should there be a rapid rise in downstream pressure for any reason, the secondary pilot will respond quickly, and will pressurize the top chamber. This will compliment the primary pressure reducing controls and provide faster response.

Ideal for applications where failure is not an option
Includes a back-up system to protect against diaphragm or pilot failure
Reduces unnecessary maintenance
Provides downstream surge protection
