106 / 206-DW

Deep Well Pump Control Valve – Double Chamber

  • Prevents pump starting and stopping surges
  • No energy loss while pump is running
  • Separate opening and closing speed controls
  • Discharges initial air/water silt to waste, on well applications.
  • Discharges stagnant water at start-up from dormant wells

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.

Specifications

  • The valve shall be a Singer Valve model 106-DW / 206-DW, size “_____”, ANSI Class 150 (ANSI 300, ANSI flanges drilled to ISO PN 10 / 16/ 25 or 40) pressure rating / flange standard, globe (angle), style valve. Solenoid Valve shall be four-way de-energized to open valve, with a 120 VAC / 60 Hz (220 VAC / 50 Hz or 240 VAC / 60 Hz) solenoid coil. Assembly shall be according to Schematic A-7514C.
  • The valve shall be normally open. On pump start-up, a pilot solenoid is energized to close the valve, at a rate governed by the closing speed control. Separate flow control valves and a double chamber design will allow opening and closing speeds to be adjusted independently. When the solenoid is de-energized the valve slowly opens while the pump continues to run. When the valve is almost fully open and all flow has been diverted as a result of the pipeline check valve closing, a stem-mounted cam triggers the limit switch to stop the pump.
  • Refer to Main Valve section, page 11, 106-PT (or 206-PT) for detailed information pertaining to valve sizes and materials, selection criteria and specifications.

106 / 206-PG-BPC

Booster Pump Contol Valve – Single Chamber

  • Substantially reduces pump starting and stopping surges
  • Separate opening and closing speed controls
  • Cost effective pump control system
  • Optional internal mechanical drop check reduces power failure surge

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.

Specifications

  • The valve shall be a Singer Valve model 106-PG-BPC / 206-PG-BPC, size “_____”, ANSI Class 150 (ANSI 300, ANSI flanges drilled to ISO PN 10 / 16/ 25 or 40) pressure rating / flange standard, globe (angle), style valve. Solenoid valve shall be three-way de-energized to close valve, with a 120VAC/ 60Hz (220 VAC/ 50 Hz or 240 VAC/ 60 Hz) solenoid coil. Assembly shall be according to Schematic A-7254C.
  • The Booster Pump control valve will eliminate surges associated with the normal stopping and starting of booster pumps. On pump start-up, a pilot solenoid is energized to begin opening the valve, at a rate governed by the opening speed control. Opening and closing speeds are adjusted independently.
  • When the solenoid is de-energized, the valve slowly closes while the pump continues to run. When the valve is almost fully closed and flow is virtually zero, a stem-mounted cam triggers the limit switch to stop the pump.
  • Refer to Main Valve section, page 11, 106-PG (or 206-PG) for detailed information pertaining to valve sizes and materials, selection criteria and specifications.

106 / 206-EF-8837BX

Excess Flow (Burst Control) Valve

  • Tight shut-off when flow exceeds a pre-determined amount
  • Manual re-activation required after failure
  • “Failure Signal” options available

The 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.

Specifications

  • The valve shall be Singer Model 106-EF-8837BX or 206-EF-8837BX, size “___”, ANSI Class 150 (ANSI 300, ANSI flanges drilled to ISO PN 10 / 16 / 25 / 40) globe / angle style valve. Assembly shall be according to Schematic A-8837BX. Performance Requirements: The valve must trip consistently within 5 % of the nominal tripping flow and will consistently not trip at 90% of the nominal tripping flow.
  • Refer to Main Valve section, see page 11, 106-PT or 206-PT for detailed information pertaining to valve sizes and materials, selection criteria and specifications.
  • Refer to Pilot and Accessories section, see page 249, Model 625-RPD Normally Closed Pilot for detailed information pertaining to materials and specifications.

106 / 206-RF

Rate of Flow Valve

  • Accurately limits flow to a pre-set maximum
  • Easily adjustable flow limit
  • Paddle-style orifice plate included
  • Optional orifice plate housing

The 106-RF and 206-RF rate of flow control valves 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.

Specifications

  • The valve shall be a Singer Valve model 106-RF / 206-RF, size “_____”, ANSI Class 150 (ANSI 300, ANSI flanges drilled to ISO PN 10 / 16 / 25 or 40) pressure rating / flange standard, globe (angle), style valve. The Model 160-RF Rate Of Flow Pilot shall have a flow set-point, preset at Singer Valve to “___” USGPM (Liters/ Second). Assembly shall be according to Schematic A-7427C.
  • The valve maintains a relatively constant flow rate by sensing the pressure differential across the specially sized orifice plate (Orifice housings are provided as an option only). The flow rate is adjustable by changing the pilot’s setting (differential across orifice). When the pressure differential is less than the set-point the valve opens allowing flow to meet pre-determined demand. When the pressure drop across the orifice exceeds the set-point, the valve closes slightly, limit flow to the preset maximum.

Anti-Cavitation Control Valve

  • Solves high pressure drop problems
  • Controls variable flows & vibration
  • Significantly reduces noise
  • Self-contained – actuators not required
  • Customizable to meet your application needs

The 106-AC series control valve is designed to solve high pressure drop problems by allowing smooth control and protection from cavitation damage. It’s ideal for applications where large pressure differentials preclude the use of standard automatic control valves and varying flows make orifice plates ineffective.

The AC control valve contains two heavy stainless steel sliding cages that maximize the full flow capacity. The first cage directs and contains the cavitation recovery, allowing it to dissipate harmlessly. While the second cage allows further control to a level as low as atmospheric pressure downstream. The cages are engineered to meet the flow / pressure differential of each application.

  • The valve shall be utilized where large pressure differentials preclude the use of standard automatic control valves due to cavitation damage and the resulting excessive wear, noise and vibration. The Anti-Cavitation Valve shall reliably control varying flows making orifice plates and/or multiple valves utilized in series ineffective and therefore unacceptable.

106 / 206-BPC

Booster Pump Control Valve – Double Chamber

  • Suitable for most pumping applications including suction lift and low differential head
  • Prevents pump starting and stopping surges
  • Built-in non-slam mechanical check reduces surges on loss of power
  • Separate opening and closing speed controls

The 106-BPC and 206-BPC booster pump control valves are installed in-line, directly downstream of the pump discharge.

The pump control valve is normally closed and on pump start-up, a pilot solenoid is energized to open the valve, at a rate governed by the opening speed control. When shut-down is required the pilot solenoid on the valve is de-energized to commence closing. The pump is kept running while the valve slowly closes. When the valve is almost fully closed and flow is virtually zero, a stem mounted cam triggers the limit switch to stop the pump.

In the event of a power failure, the built-in mechanical drop check closes immediately when the flow stops, independently of the valve position. Surges are minimized by closing the valve before reverse flow occurs.

Specifications

  • The valve shall be a Singer Valve model 106-BPC / 206-BPC, size “_____”, ANSI Class 150 (ANSI 300, ANSI flange drilled to ISO PN 10 / 16/ 25 or 40) pressure rating / flange standard, globe (angle), style valve. Solenoid valve shall be four-way de-energized to close valve, with a 120VAC / 60Hz (220 VAC / 50 Hz or 240 VAC/ 60 Hz) solenoid coil. Assembly shall be according to Schematic A-0426H.
  • The Booster Pump control valve will eliminate surges associated with the normal stopping and starting of booster pumps. On pump start-up, a pilot solenoid is energized to begin opening the valve, at a rate governed by the opening speed control. Separate flow control valves and a double chamber design will allow opening and closing speeds to be adjusted independently.
  • When the solenoid is de-energized, the valve slowly closes while the pump continues to run. When the valve is almost fully closed and flow is virtually zero, a stem-mounted cam triggers the limit switch to stop the pump.
  • In the event of power failure while the pump is running, or other sudden stoppage of the pump, an internal drop check valve will prevent reverse flow back through the valve or pump.
  • Refer to Main Valve section, page 11, 106-PTC or 206-PTC, page 33, for detailed information pertaining to valve sizes and materials, selection criteria and specifications.
  • Refer to Pilot and Accessories section, page 249, Micrometer Flow Control Valves for detailed information pertaining to materials and specifications. Solenoid specification information is available from Singer Valve only at this time.
