Singer Valve Leakage and
Water Loss Management Products

While some of these products are standard offerings and are listed elsewhere in our Full Product Catalog with complete technical information, other products are shown in this section only with a basic overview supplied. If technical information is required on any of these innovative offerings please contact your local Singer representative or the factory.

In addition, there are many other offerings within this web site page that can greatly reduce leakage and water loss that are not included in this section. If you are concerned about overflowing tanks and level management, please refer to our Level Control Section. If you are concerned about Transient Pressures and the resulting pipe breaks, please refer to our Pump Control and/or Relief / Sustaining / Surge Sections.

We have proudly assisted customers around the world reduce leakage and water loss through the correct application of our varied product offerings. Singer Valve truly does provide “Result-Based Solutions. Globally.”

Leakage-Related Singer Valve Products

Model PR One Adjustable Set Point Ideal for most Pressure Ranges • Pressure Reducing Valve • Maintains a CONSTANT DOWNSTREAM PRESSURE regardless of fluctuations in supply pressure or flow • Many combinations and variations of functions possible with other pilots and features added • Stable low flow • Precise and easily adjustable downstream pressure See this page for more information. Contact Singer Valve for schematic and specifications.

Model PR-8761A One Adjustable Set Point Ideal for Extremely Low Pressure • Maintains a CONSTANT DOWNSTREAM PRESSURE regardless of fluctuations in supply pressure or flow • High capacity pilots ensure valve opens fully when needed, and optimum modulation when required • Purely hydraulic operation, uses no electronic controls or external power source • Suitable for systems with occasional low supply pressure (10 psi or less*), PR-8761A ensures distribution gets maximum available pressure under low supply condition • When supply pressure drops, valve opens fully. When supply pressure recovers, valve modulates to maintain downstream pressure desired Contact Singer Valve for schematic and specifications. *Consult factory for further details.

2PR-SC Two Adjustable Set Points Selectable Using Solenoid Control • Pressure Reducing Valve with two set points, high pressure and low pressure • Solenoid selects between high and low pressure setting, available in 24 VDC, 110 VAC, 220 VAC (normally open or closed) options • Reduces system pressure when not needed (low flow demand or night time), supplies proper pressure when required (high flow demand or day time) • Solenoid can be connected to SCADA or timer to select high pressure during daytime, and low pressure during night time Contact Singer Valve for schematic and specifications.

2PR-SC-BT Two Adjustable Set Points Selectable Using Battery Operated Control • Pressure Reducing Valve with two set points, high pressure and low pressure • Time-based selection via latching solenoid and timer • Self-contained, powered by two 9-volt batteries • 24/7 time settings (can skip days) • Multiple time possible (up to 10 time settings per 24 hour period). • Similar to 2PR-SC; that is, reduces system pressure when not needed (low flow demand or night time), supplies proper pressure when required (high flow demand or day time) • Recommended for systems where no external power source is available Contact Singer Valve for schematic and specifications.

Model PR-420 (AC/DC) Set Point Fully Controlled by SCADA • Pressure Reducing Valve with electronic actuator • 420(AC/DC) allows remote adjustment of pilot via 4-20mA from SCADA • Low power (less than 0.3Amp draw) actuator available in 24VDC or 120/240VAC • Easy-to-use software allows field calibration. • Fail safe operation, valve controls to last adjusted setpoint on power or signal failure • PR-420(AC/DC) maintains a CONSTANT DOWNSTREAM PRESSURE regardless of fluctuations in supply pressure or flow. The electronic actuator allows SCADA operators to adjust pressure setpoint remotely via 4-20mA • Using sophisticated controllers, the valve can be configured to automatically adjust the pressure setpoint depending on time of day or flow demand See this page for more information. Contact Singer Valve for schematic and specifications.

Model PFC Pressure Increases / Decreases Subject To Flow Variations • Pressure Flow Control • A patented pressure reducing valve that increases the controlled downstream pressure as flow increases • The maximum increase in pressure is adjustable from 0 to 30psi (2 Bar) above base pressure. Simple hydraulic action will operate normally while submerged. Requires no electrical supply or batteries • Reduce water loss substantially • Maintain constant pressure at remote locations • Reduce Nighttime line breaks • Automatically reduces pressure and can vary downstream pressure according to flow • Supplies water at preferred pressures under all flow conditions • Existing valves can be field upgraded See this page for more information. Contact Singer Valve for schematic and specifications.

Model 106-PM Mutiple Set Points Responds To Time Settings Or Flow Demand • Pressure reducing valve with self-contained PRV controller and actuator • Improves pressure during periods of peak demands • Reduces pressure when demand is low • Reduces losses thru leakage • Active pressure management by continuous adjustment via Time-based Control or Flow-based Modulation (separate flow meter required) • Self-contained, battery operated system. 3-Year rating on battery. • Waterproof and submersible (IP 68) • Can be remotely adjusted • Data-logging capability Contact Singer Valve for schematic and specifications.
