74700 Overflow Valve
Operating principle
Under normal operating conditions, the overflow valve remains closed.
The valve is calibrated to a specific pressure by regulating the spring with the pressure nut.The calibrated pressure is a maximum safety pressure defined to avoid damage of the plant.
When the pressure in the circuit exceeds the calibrated pressure, the valve opens letting the flow pass and reducing the pressure of the pipe system.
The valve can incorporate a handle designed to partially open the valve. When the handle is kept in the open position during the CIP process, the cleaning products can pass through the valve.
Design and features
The valve is normally closed.
Easy to adjust manually.
