Hydraulic valve cartridge pressure reducing valve PBFB-LAN

The working principle of the relief valve is easy to understand, and it is a common safety valve that can control the damage caused by excessive expansion of the fluid. The relief valve is characterized by a unique design, which can not only control the flow rate, but also prevent the generation of excessive pressure, so as to protect the smooth operation of the system and reduce losses. The relief valve is generally divided into steam or liquid relief valves. The steam relief valve is usually composed of a valve body, a spool and a valve cover. When the pressure in the system exceeds the set value, the spool will rise, the outlet will be reduced, and the excess
The steam is discharged from the system, and the reaction force is counteracted to stabilize the steam valve pressure below the set value. The gas relief valve is generally composed of the valve body, spool, valve, thrust screw, rubber pad, seat cover and so on. When the pressure rises beyond the set value, the seat cover is equipped with upper, lower, top, grid plate and piston to increase the friction between the seat cover surface and the valve body, open the piston rod rod and piston port, so that the fluid overflows the system.
Relief valve is generally used in gas delivery systems, such as gas generators, pipelines and equipment, play a protective role, when the pressure of the medium is greater than or equal to the set value, the relief valve is closed, when the pressure of the medium is less than the set value, the relief valve is opened. In addition, the relief valve can be used for common household equipment, such as chillers, air conditioners and washing machines, which can protect these equipment from excessive pressure damage, and make full use of their margin to ensure the stable operation of the equipment.
All in all, the relief valve prevents excessive pressure from damaging the system by controlling excess pressure. In addition, it can effectively limit the flow, protect the system from damage, and ensure the normal operation of the equipment.
