WATER WORKS

420-DC/AC

Automated Pilot Control

  • IP68, 7 ft/24 hours (2.134 m/24 hours)
  • Programmable span and speed via USB cable and software
  • Built in surge suppression for protection against voltage spikes
  • Position feedback: 4-20 mA
  • Downstream pressure follows the control signal within +/- 1 psi / 0.068 bar

The 420-DC or 420-AC provide for a reliable, simple and cost efficient way to automate today’s water systems. A sturdy slow speed 24 VDC motor actuator drive can be installed on a variety of Singer pilots. The motor actuator responds to a 4-20 mA signal, rotating the pilot adjusting screw corresponding to the change in signal. The number of turns is adjustable and may be programmed to suit the pressure changes required for the application.

Typical Applications for a 420-DC/AC:

- Pressure management systems - utilizing pressure reducing pilot to give adjustable pressure settings based on system demand.
- Remote or difficult to reach control valves where adjustments need to be made and using SCADA is the best option.

106 / 206-2SC-PCO

Dual Solenoid Control for Positioning and SCADA Controls

  • Precise control from remote locations
  • Process controller compatible
  • Minimal power needed for stand-by operation

A106-DL

Dynamic Lifter Spring Pressure Relief Valve

  • Low maintenance
  • Hygienic and minimal time to flush and test operations
  • Premium materials reduce maintenance, providing the lowest long-term cost of ownership

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

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.

106 / 206-RPS Relief

Pressure Relief Valve

  • Quick opening relief
  • Easily adjustable pressure setting

The 106-RPS and 206-RPS pressure relief valves are based on the 106-PG and 206-PG main valves.

The 81-RP pilot senses the upstream pressure through a connection to the valve inlet. The valve and pilot remain closed until the inlet pressure exceeds the pilot setting. The valve opens rapidly to relieve damaging overpressure and closes smoothly at an adjustable speed, when the pressure returns below the set-point. The upstream pressure is limited to the pilot set-point.

  • The valve shall be a Singer Valve model 106-RPS / 206-RPS, 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 81-RP Pressure Relief Pilot (Normally Closed Pilot) spring range shall be “___ to ___” psi / bar, with set-point preset at Singer Valve to “___” psi / bar. Assembly shall be according to Schematic A-0423F.
  • The valve shall remain closed until inlet pressure exceeds a pre-determined set- point at which time the valve opens quickly and modulates to limit the upstream pressure to the pre-determined set-point.
  • 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.
  • Refer to Pilot and Accessories section, page 249, Model 81 Pressure Relief Pilot (Normally Closed Pilot) for detailed information pertaining to materials and specifications.

Note

  • Where UL / FM designation is required, specify 106-RPS-8700A. Available in 2-1/2 in / 65 mm to 8 in / 200 mm globe and angle configurations, ANSI 150 and ANSI 300 flanges, and grooved end connections.

106 / 206-RPS Sustaining

Pressure Sustaining Valve

  • Ensures minimum upstream pressure for critical use
  • Easily adjustable pressure setting
  • Closes if inlet pressure drops below set-point

The 106-RPS and 206-RPS pressure sustaining valves are based on the model 106-PG or 206-PG main valve.

The 81-RP pilot senses the upstream pressure through a connection to the valve inlet. The valve and pilot remain closed until the inlet pressure exceeds the pilot setting.

Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm.

Should the upstream pressure fall below the set-point, the valve will close or modulate to ensure that the set-point is maintained.

  • The valve shall be a Singer Valve model 106-RPS / 206-RPS, 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 81-RP Pressure Relief Pilot (Normally Closed Pilot) spring range shall be “___ to ___” psi / bar, with set-point preset at Singer Valve to “___” psi / bar. Assembly shall be according to Schematic A-0423F.
  • The valve shall maintain a minimum pre-determined upstream pressure. When the actual upstream pressure meets the minimum allowable pre-determined upstream pressure setting the valve will either close or modulate in order to maintain the minimum allowable upstream pressure.
  • 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-RPS-RR

Surge Anticipating on Rate of Rise of Pressure Relief Valve

  • Protects against power failure surges or pressure waves caused by velocity changes
  • Unaffected by header pressure and over sizing
  • Quick opening relief
  • Easily adjustable pressure setting
  • No electrical services required

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.

  • The valve shall be a Singer Valve model 106-RPS-RR / 206-RPS-RR, 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 81-RP Pressure Relief Pilot (Normally Closed Pilot) spring range shall be “___ to ___” psi / bar, with set-point preset at Singer Valve to “___” psi / bar.
  • Assembly shall be according to Schematic A-7340F, 2 in / 50 mm to 6 in / 150 mm 106, and 3 in / 75 mm to 8 in / 200 mm 206 (for A-7340F1 [not shown], 8 in / 200 mm and larger 106). The valve will open rapidly on an over-pressure caused by sudden pump stoppage due to power failure or other means, and other causes of surges in the pipeline.
  • The valve will also anticipate a surge by sensing a rapid increase in pressure as the surge wave returns and opens fully with no stroke limiters on the valve opening.
  • The valve will begin slowly closing when the system pressure falls below the high pressure set-point of the valve piloting until it fully closes regardless of static pressure in the pipeline.
  • Refer to Main Valve section, see page 11, 106-PG (or 206-PG) for detailed information pertaining to valve sizes and materials, selection criteria and specifications.
  • Refer to Pilot and Accessories section, see page 249, Model 81 Pressure Relief Pilot (Normally Closed Pilot) and Model 81-RPD Differential Pressure Pilot for detailed information pertaining to materials and specifications.
