Pump Control

106 / 206-HC

Hydraulic Check Valve

  • Drip-tight seat
  • Independently adjustable opening and closing speed controls

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.

Specifications

  • The valve shall be a Singer Valve model 106-HC / 206-HC, 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 Opening Speed Control shall be adjusted in the field to allow for slow opening. Closing speed should be field adjusted to permit slow closing after allowing surges through the valve and back to the source preventing damage (check with pump supplier to determine if backflow through pump is acceptable). Assembly shall be according to Schematic A-0422D.
  • The valve shall open for normal direction of flow and close to prevent reverse flow. Opening and closing speeds shall be individually adjusted to prevent surges. The valve shall be installed allowing for flow over the seat (flow is in the opposite direction through the valve as compared to other standard function categories).
  • Refer to Main Valve section, page 11, 106-PG / 206-PG for detailed information pertaining to valve sizes and materials, selection criteria and specifications.

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.

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.

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.
