Under normal operating conditions, the 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.
Connections FIL-IDF, BS-RJT, SMS, Clamp, flanges, Macon.
Gaskets available in NBR and FPM.
Several operating ranges (changing the spring).
The assembly of the handle allows to partially open the valve in order to allow the passage of fluid for CIP cleaning (for use with positive pump bypass).
Safety seal to identify the factory calibration.
