Series 125 - Pump Control Valves

The OCV Series 125 and 126 Pump Control Valves are designed to effectively eliminate the surges associated with the starting and stopping of the pump. Electrically interfaced with the pump motor, the valve opens and closes at an adjustable speed, providing a smooth, predictable transition of pump discharge pressure and volume into the system.

125 Booster Pump Control

Models 125 and 125-27, designed primarily for booster pumps, are installed inline, on the discharge of the pump. These valves also include a check feature that eliminates any need for a separate pump check valve.

126 Deep Well Pump Control

Model 126, designed for deep well pumps, is installed on a bypass line between the pump discharge and the pump check valve. The Model 126 eliminates debris and air on pump start.

Valve Operation

Model 125 and 125-27, designed primarily for booster pumps, are installed inline, on the discharge of the pump. They are normally closed with the pump off, open slowly after the pump starts, and close slowly prior to pump shutdown. In this way, flow is slowly and smoothly transitioned to and from the system. These valves also include a check feature that will close the valve in the event of a power failure while the pump is running. Thus, they eliminate any need for a separate pump check valve.

Model 126, designed for deep well pumps, is installed on a bypass line between the pump discharge and the pump check valve, and discharges either to waste or back into the well itself. It is normally open with the pump off, closes slowly after the pump starts, and opens slowly prior to pump shutdown. In this way, flow is slowly and smoothly transferred from the bypass to the system, and vice-versa.
