control valves for the global water industry including Pressure Reducing, Pres-
sure Relief/Sustaining, Altitude and Pump Control Valves.
Project Highlight:
Customer: Craven County Water Department (New Bern, NC)
Project: Potable Water Supply System
Details: ACSC was subcontracted by Shook Construction (Apex, NC) to construct
eight (8) new water supply wells and their corresponding pump houses. Pump
station construction included the installation of all pumps, motors, piping and 24
Singer Valves – three (3) at each site. ACSC provided all of the labor, equipment and
materials to install the valves listed below:
• 106-DW Deep Well Pump Control Valve is the main valve in the three (3) valve application. This 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.
– The valve prevents pump starting and stopping surges.There is no energy loss while pump is running.
– The valve separates opening and closing speed controls, discharges initial air/water silt to waste, on
well applications and discharges stagnant water at start-up from dormant wells
• The additional valves in this application are the 106-HC Hydraulic Check Valve that allows one way flow
only and the 106-RPS-L&H Surge Anticipating Relief Valve that is designed to anticipate surges to avoid
severe water hammer often associated with power failure surges.
