Deep Well Pump Control Valve with High Capacity Solenoid
The Cla-Val Model 61-47 Deep Well Pump Control Valve is designed to protect pipelines from surges caused by the starting and stopping of deep well pumps. The operation of the valve is completely automatic and controlled by the solenoid valve. With the pump off, the valve is wide open. When the pump is started, the solenoid is energized and the valve begins to close slowly, discharging air and the initial rush of sand and water from the pump column to the atmosphere. As the valve closes the pump output is gradually diverted into the main line, preventing the development of a starting surge.
