A filter must be installed before the 500X pressure relief valve and the pressure holding valve. When adjusting, the screw on the pilot valve should be withdrawn, the water pump should be started to discharge from the pressure relief valve, and the adjusting screw should be gradually screwed in to gradually increase the pressure until the required set pressure is reached. Tighten the nut after adjustment.

PHP is an independent proportioning and mixing system that automatically adjusts according to flow and pressure. It is usually installed near the foam tank and connected to the foam tank, fire pressure water source and foam generating equipment through pipes. When a fire occurs, the foam pump starts to suck the foam from the foam tank into the proportioning mixer pipe. After being adjusted by the pressure balance valve and the proportioning mixer, a certain amount of foam is injected into the pressure water flowing through the proportioning mixer and forms a concentrate, which then flows to the foam generating equipment, such as foam guns, foam cannons, etc., and finally produces foam fire extinguishing.

The foam proportioning device is suitable for oil tank areas and refineries, petrochemical enterprises, hangars, port areas, cargo storage yards, warehouses, gas stations, paint storage areas, etc.

In firefighting, two way inlet dividing water breeching play a vital role.

The UL-FM water flow indicator is a component of the automatic sprinkler fire extinguishing system, which is generally installed on the water distribution main or the beginning of the water distribution pipe on the system network side. When the blade senses the water flow signal, it will convert the water flow signal into an electrical signal. After receiving the signal, the automatic alarm controller will issue a command pneumatic alarm system or start electrical equipment such as fire pumps, and can display the firearea. This product is suitable for wet, dryand pre-action automatic fire extinguishing systems.
