Operating principles: 

_The valve is normally closed. 

_The valve is calibrated to a special pressure by adjusting the spring with a pressure nut. 

_When the pressure in the pipeline exceeds a certain pressure, the valve opens and allows fluid to pass, thereby reducing the pressure in the pipeline. 

–The valve can be fitted with a handle to partially open the valve. When the handle remains open during the on-site cleaning process, the cleaning product can flow through the valve.
