CHFIRE 200X pressure reducing valve flange is an important component used in various industries such as oil and gas, chemical, and water treatment. It works by reducing the high pressure of the fluid flowing through the pipeline to a lower pressure level that is suitable for the downstream applications.
The pressure-reducing valve is adjusted to reduce the inlet pressure to a desired outlet pressure and rely on the energy of the medium itself to keep the outlet pressure automatically stable. From fluid mechanics point of view, pressure reducing valve is a throttling element, local resistance to change that by changing the throttling area, change the kinetic energy of the flow velocity and fluid, different pressure loss, so as to achieve the goal of decompression. Then the control and adjustment system can be adjusted to balance the pressure fluctuation of the valve and the spring force, so that the pressure of the valve remains constant within a certain margin of error. It is widely used in high rise buildings, water pressure of the city water supply pipe, and other occasions, so as to ensure the proper service water pressure and flow of water points in the water supply system.

200X pressure reducing and stabilizing valve consists of main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge to form hydraulic control takeover system. When in use, after the outlet pressure is adjusted, it can automatically maintain a stable outlet pressure.
200X pressure reducing valve is a valve used to adjust the water supply direction in a water supply system where fire water and domestic water are connected in parallel. When a fire occurs, the firefighting department urgently needs a large amount of water, and the domestic water supply is immediately cut off to ensure sufficient water for firefighting; when the firefighting stops using water and the pressure decreases, the valve automatically opens and is in a normally open state to restore the domestic water supply. This valve eliminates the need for a separate firefighting water supply network, greatly saving construction costs and water consumption. The valve has high control sensitivity, is safe and reliable, is easy to debug, and has a long service life.
Flanged globe type pressure relief valve (Fire pump relief valve) is used in the discharge of fire pump with flanged connection. It automatically relieves excessive pressure, so to maintain constant pressure. It allows the fire pump to be stopped without causing surging.
A Pressure Relief Valve is defined by NFPA 20 (3.3. 67.5 Relief Valve) as “A device that allows the diversion of liquid to limit excess pressure in a system.” In general, a PRV is a safety device, designed to protect a pressurized system during an overpressured event.
The pressure relief valve (500X) is a hydraulic control valve, mainly used in fire protection or other water supply systems to prevent system overpressure and maintain the pressure of the fire water supply system. When the pressure in the water supply pipeline exceeds the set pressure of the pressure relief valve, the pressure relief valve will release the pressure in time to protect the safety of the pipeline.
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.
500X pressure relief valve is a device used in water supply pipe network systems and urban water supply projects in high-rise buildings and living areas. The device consists of a main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge to form a hydraulic control takeover system. It uses hydraulic automatic operation and can be used as a pressure relief valve or a pressure holding valve.
The 500X pressure relief/pressure holding valve consists of a main valve, a pressure relief/pressure holding pilot needle valve, a ball valve, a micro filter and a pressure gauge to form a hydraulic control takeover system. It can be used as a pressure relief valve or a pressure holding valve by hydraulic automatic operation. When used as a pressure relief valve, it can maintain the water supply line pressure below the set safety value; when used as a pressure holding valve, it can maintain the upstream water pressure of the main valve above the set value and maintain the upstream water supply pressure of the main valve.
500X pressure relief and pressure sustaining valve is mainly used to adjust the medium flow, pressure, temperature, liquid level and other process parameters in the field of industrial automation process control. According to the control signal in the automation system, the valve opening is automatically adjusted to achieve the adjustment of medium flow, pressure, temperature and liquid level.
A Pressure Reducing Valve (PRV) is an Automatic Control Valve designed to reduce a higher unregulated inlet pressure to a constant, reduced downstream (outlet) pressure regardless of variations in demand and/or upstream (inlet) water pressure.
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.
Inline Balance Pressure Foam Proportioner (ILBP) is used with positive displacement foam concentrate supply pump. The system controls accurate flow of foam concentrate into the water stream over a wide range of flow rate and pressure.
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 Line Balanced Pressure Proportioning Systems (ILBP) allow the selection of either foam or water to every discharge device within the foam system.
The balanced foam proportion mixing device is a relatively advanced foam fire extinguishing device, which is particularly suitable for important fire fighting projects such as petrochemical enterprises, large oil depots, oil terminals and offshore drilling platforms.
The Siamese twins inspired the design of the Siamese connection. Hence the Y-shaped design with two inlets that connect the two hoses. The two inlets help the firefighters to attach the two hoses. These direct the water to refill the fire sprinkler system or the standpipe system.
In firefighting, two way inlet dividing water breeching play a vital role. They are not only a key component in firefighting equipment, but also an important guarantee for firefighters to perform their tasks safely and efficiently. By deeply understanding the functions and usage of water distributors, we can better understand their indispensable role in firefighting.
Portable fire water cannon, as a highly efficient firefighting and rescue equipment, is widely used in various scenarios.

It has the characteristics of adjustable flow, long range, multiple functions, small size and good performance. It is particularly suitable for spaces where the fire scene is far away from the water source and the fire truck cannot enter.
The DSP flow splitter is used to divide one water flow into multiple flows. It is equipped with one DSP inlet and two or three DSP outlets. For the outlets, they are available in normal type or gated type with quarter-turn processor to shut off the water flow individually.
Dividers are used for distributing the extinguishing medium from one feed line over two hose lines, to obtain an optimum supply of extinguishing water. Screw down valves for easy and quick controllability as a shut-off device.
Fire water diverter is a key device widely used in fire protection system. Its main function is to divide a fire hydrant pipeline into two, thereby improving the utilization rate of fire water source and ensuring that each branch can provide sufficient water supply pressure. This equipment is usually used in large public places, commercial facilities and high-rise buildings where decentralized water supply is required to improve the efficiency and accuracy of fire protection operations.
