Compelled by the State Water Board, an Eastern US municipal water company recently abandoned an existing surface water treatment plant and developed two new production wells for their water supply. The project team ultimately determined that the best pump control approach was to use a combination booster pump control valve, air release valves, pressure relief valves and a control panel that could be integrated with the existing SCADA system.
The installed equipment included Cla-Val’s 60 Series Pump Control Valve, 50 Series Pressure Relief Valves, 33A High Performance Air Release Valves and the PC-22D Pump Control Panel.
The PC-22D controls the pump and valves to prevent surges in the system when the pump starts or stops. It consists of a pre-wired electrical control panel employing an integral controller (Cla-Val Model VC-22D) to sequence the pump and valves during all modes of operation. The programmable valve controller, which is housed in a NEMA 4X rated enclosure, provides protection to the pumping system from damage due to mechanical, hydraulic or power failure. The controller is unique in that its capabilities allow for either stand-alone operation or integration into a SCADA system with standard wired signals or Modbus (TCP or RTU) communications.
Using the valve controller’s intuitive programming screens, a customized ValvApp™ was developed to operate the pump and valves, resulting in a quick transition to the new water supply. This turnkey solution offered by Cla-Val enabled the municipal water utility to put the wells in operation with the valves and control equipment coming from just one supplier.
