Non-Modulating Float Valve
The 106-F-Type 5 and 206-F-Type 5 non-modulating float valves are based on the 106-PG or 206-PG main valve. It is ideal for allowing normal forward flow to fill water reservoirs to a desired high level and where the pilot and valve of the reservoirs are easily accessible.
The valve functions as a two position valve, either open or closed. The valve remains closed when the reservoir level drops, until the float reaches the pre-determined adjustable minimum reservoir level. The F-Type 5 valve then opens to refill the reservoir and closes tightly when high water level is achieved.

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.
One-Way Flow Altitude Control Valve with Differential Control
The 106-A-Type 4 and 206-A-Type 4 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 4 allows normal forward flow to fill the reservoir to the maximum level, then closes drip-tight at the set-point. It opens to refill the tank once the level drops an adjustable amount below the high water level.
Distribution from the reservoir is through a separate pipeline.
Note: This valve does not operate as a check valve to prevent reverse flow.
Specifications
Two-Way Flow Altitude Control Valve with Differential Control
The 106-A-Type 3 and 206-A-Type 3 altitude control valves are based on the 106-PG or 206-PG main valve, and are ideal for maintaining preset maximum level.
The Type 3 allows normal forward flow to fill the reservoir to the maximum level, then closes drip-tight at the set-point. The valve opens to permit reverse flow through the valve when the supply pressure drops an adjustable amount below the reservoir head.
The Type 3 will then allow normal forward flow to refill the tank to the maximum level, when a higher supply pressure is restored.
Specifications
Electronic Flow Control and Metering System
The Singer models 106-2SC-MV and 206-2SC-MV electronic flow control and metering valves are based on the 106-PG or 206-PG main valve.
The pressure in the upper operating chamber is controlled by operating the pilot solenoids. The PLC within the MV1-TP control panel determines whether the opening solenoid or the closing solenoid is operated. The change in valve position is dependent upon which solenoid is operated and the duration of the energized period.
The Singer MV1-TP control panel computes the flow rate based on valve differential pressure and position and operates the pilot solenoids to match the flow rate to the customer’s pre-determined (adjustable) set-point. Flow is totalized and displayed via panel readout. In addition, the MV1-TP panel includes a pre-programmed logic controller, touch screen display, labelled wiring and terminal strip.
One-Way Flow Altitude Control Valve
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.
Specifications
Two-Way Flow Altitude Control Valve
The 106-A-Type 1 and 206-A-Type 1 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 1 allows normal forward flow to fill the reservoir to the maximum level and then closes drip-tight at the set-point. It opens to allow reverse flow through the valve when the supply pressure drops a fixed amount below the reservoir head.
When a higher supply pressure is restored, the Type 1 valve will then allow normal forward flow to refill the tank to the maximum level.
Specifications
Pressure Flow Control (Modulation) Valve
The 106-PFC / 206 PFC Pressure Modulation Valve is a pressure reducing valve with a special (Patented) pilot that increases downstream pressure as flow increases.
The PFC valve alters and controls pressure with flow to create virtually constant pressure at the critical pressure point in a system. It will also automatically adjust for distribution friction losses. The PFC valve will deliver consistent performance as it has no electrical components and is not affected should the valve chamber be flooded. The valve may be used wherever a standard PRV is installed.

Pressure Reducing Control Valve with Integral Back-up
Product Overview
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.

Reduced Port, Integral Back-Up, Dual Diaphragm, Automatic Control Valve
The 206-PGM and S206-PGM control valves are designed for particularly sensitive applications or situations where valves are difficult to access and maintain.
The PGM series control valves provide integral back-up control and the ability to signal should the desired function move off limits. It can also provide an independent and very positive override.
It is a variation of the standard single chamber 106-PG valve with modifications that add the following features:
• Back-up diaphragm
• Completely self-contained
• Modulating or emergency close back-up
• Back-up components kept out of the main stream until required
• Extremely positive shut-off
• Emergency close for security breach or earthquake
The PGM series control valves may be combined with additional Singer Valve specific accessories to add further customization such as:
• Back-up pilot system
• Annunciation with a Single Pole Double Throw Limit Switch
