[product use]
The 500X (A742X) PN10~PN25 pressure relief holding valve can release the pressure in the pipe above the safety value of the guide valve and maintain the pressure in the pipe below the safety value to prevent the pipeline or equipment from being damaged by high pressure or SURGE in the pipe. It can be used to relieve the pressure of fire test circulation system in high-rise buildings to prevent the system from being endangered by excessive water pressure. Pressure holding valve: can maintain the upstream water supply pressure of the main valve above a certain set value to protect the pressure of the upstream water supply area of the main valve.
Scope of use: the product can be used to adjust the process parameters such as medium flow, pressure, temperature and liquid level in the field of industrial automation process control.
The product conforms to the standard: JB/T 10674.
