Product Description:

8500X type groove pressure relief valve can effectively release the pressure that exceeds the safety setting value of the pilot valve on the pipeline to prevent damage to the pipeline and equipment due to overpressure. This valve is mainly used for pressure relief in the fire test circulation system of high-rise buildings to prevent system failure due to excessive water pressure.' The water supply pressure upstream of the main valve can be maintained above a certain set value to ensure the pressure in the water supply area upstream of the main valve.
It is installed in the pipeline and used for cutting off and opening. It can be turned on or off as a remote control. It can replace the gate valve or butterfly valve for opening and closing the large
electric operating machine, and the maintenance is simple.
