Features 

 Design PHKG40 pressure to open the control valve does not require interaction with the alarm system by alarm over the pressure of water that is able to start. 
 Increased time pressure reducing valve, the pressure in the tank is half than the pressure of the pipe network, to extend the useful life of the tank capsule. 

 5.0.8 stipulates clearly that the system three basic requirements: 

 A wet system from spray to spray foam conversion time, 4L / 5 flow calculation should not be greater than 3min; 
 2, foam proportioner flow is equal to and greater than 4L / S in line with a mixture of water and foam fire extinguishing agent than specified; 
 3, continued to spray the foam concentrate should not be less than 10min 
 The main bubble - water spray equipment performance
