  Pressure relief valve: The pressure in the water supply pipe that exceeds the safety threshold of the pilot valve can be released.

  
  

                 And maintain the pressure in the tube below a safe set point to prevent the tube

  
  

                 Medium or high pressure or sudden pressure (SURGE) damage to pipelines or equipment. Can be used as

  
  

                 High-rise building fire test circulation system for pressure relief to prevent water

  
  

                 Excessive pressure causes system hazard.

  
  

  Pressure holding valve: can maintain the upstream water supply pressure of the main valve above a certain set value,

  
  

                 The pressure in the upstream water supply area of the main valve is guaranteed.

  
  

  Emergency opening valve: installed at the water outlet of the fire sprinkler pump, when there is a pump outlet

  
  

                        The valve opens immediately when the pressure rises above a certain set point.

  
  

  Pressure rating: PN10, PN16, PN25

  
  

  Diaphragm type: Φ50mm~Φ70m0m
