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.

• Valve opening speed is adjustable to pump and system requirements for smooth increase in pressure.
• Valve closing speed is adjustable, gradually decreasing pressure to system as valve closes.
• Valve is interlocked with pump motor to perform unified pump and valve operation.
• Built-in reverse flow check feature.
• Valve automatically shuts off pump motor on loss of pump discharge pressure (shaft lock-up).
• Two simple field adjustments: opening speed and closing speed.
