Pump Control Valves
Cla-Val Pump Control valves are manufactured in a variety of configurations to meet critical pump control application requirements with precise performance and maximum durability.
Cla-Val 60 Series Booster Pump Control valves are designed for installation on the discharge of a booster pump to prevent pipeline surges caused by starting or stopping of the pump. When a pump is started, a solenoid control is energized and the valve gradually opens. When the pump is signaled to shut-off, the solenoid is de-energized and the valve gradually closes. Should a power failure occur, a built-in lift-type check valve closes the moment flow stops, preventing reverse flow.
Cla-Val Series 61 Deep Well Pump Control/Pump Suction Control Valves are designed to prevent pipeline surges caused by the starting and stopping of deep well pumps. A solenoid pilot valve and separate, adjustable flow control valves in the pilot system regulate opening and closing rates. With the pump off, the valve remains in the full open position. When the pump is started, the pump suction control valve begins to close slowly, discharging air and the initial rush of sand and water from the pump column to atmosphere. As the valve closes, the pump output is gradually diverted into the main line preventing development of a starting surge.
