pressure reducing valve

A pressure reducing valve is a control valve that reduces and stabilizes a higher inlet pressure at the desired outlet pressure through manual or automatic adjustment. Its core function is to stabilize and reduce pressure, maintaining the outlet pressure at the set value regardless of fluctuations in inlet pressure or flow rate. Its working principle is mainly based on force balance. Compare the preset force of a spring or induction outlet pressure (such as through a diaphragm or piston) with the predetermined force of a spring. When the outlet pressure of the self operated pressure reducing valve deviates from the set value, the force difference will drive the valve disc to move, change the valve seat opening, adjust the flow area, and ultimately automatically restore and stabilize the outlet pressure. The structure of a direct acting pressure reducing valve is simple, and it uses the outlet pressure to directly drive the valve disc, making it suitable for small diameter and low pressure drop applications. The pilot operated pressure reducing valve amplifies the control signal through the pilot valve, and the main valve responds quickly with high voltage stabilization accuracy, making it suitable for large-diameter and high-pressure differential working conditions. The main feature of pressure reducing valves produced by Kaiweixi is automatic adjustment and maintaining constant outlet pressure. They are widely used in steam systems, water supply pipelines, gas distribution, hydraulic systems, and industrial production.

Water pressure reducing valve

Water pressure reducing valve is an automatic regulating valve, whose core function is to reduce and stabilize the high and unstable fluid pressure at the inlet end to the required lower pressure value at the outlet end. It mainly controls the overcurrent area by sensing changes in the pressure on the outlet side and automatically adjusting the opening of the valve disc, thereby consuming excess pressure energy and achieving stable output. Its main structural types include direct acting (using springs and diaphragms to directly sense and adjust) and pilot operated (using pilot valves to amplify control signals, with higher accuracy, suitable for larger flow rates and pressure differentials). Valves are usually equipped with pressure regulating devices, allowing users to set the outlet pressure within a certain range. Kaiweixi Valve Group mainly produces water pressure reducing valves such as direct acting spring pressure reducing valves, diaphragm pressure reducing valves, piston pressure reducing valves, hydraulic pressure reducing valves, branch pressure reducing valves, pressure reducing valves with pressure gauges, and self operated pressure reducing valves, which are widely used in building and domestic water supply systems, fire water supply systems, industrial production water supply pipelines, and agricultural irrigation. Water pressure reducing valves are essential control equipment for ensuring the safe, stable, efficient, and economical operation of water supply systems.

Specification：
DN15~300mm
Pressure：
1.6~32Mpa
Material：
Cast iron, ductile iron, stainless steel, copper

Steam pressure reducing valve is an automatic regulating valve specifically designed for steam pipeline systems. Its core function is to reduce and stabilize the high pressure steam at the inlet end at the precise and lower outlet pressure required by the equipment. Compared with ordinary water pressure reducing valves, steam pressure reducing valves need to be designed with special consideration for harsh working conditions such as high temperature, high pressure, cavitation, and durability of sealing materials. Its typical structure is mainly a pilot piston or diaphragm type, which uses outlet pressure feedback to sensitive components (such as diaphragms) to drive the valve disc to change its opening, thereby consuming pressure energy and accurately stabilizing pressure. Kaiweixi Valve Group mainly produces pilot operated steam pressure reducing valves, piston type steam pressure reducing valves, lever type steam pressure reducing valves, electric steam pressure reducing valves, Speisak type steam pressure reducing valves and other steam pressure reducing valves, which are widely used in all industrial fields that use steam as power or heat source, such as power generation, chemical industry, pharmaceuticals, food processing, textiles and heating. Its main function is to protect equipment, save energy and stabilize voltage, and ensure safe operation. The steam pressure reducing valve is a key control device to ensure the safe, efficient, and economical operation of industrial steam systems.

Gas pressure reducing valve

Model：
Y42F/YK43F/YK43W/YK43H//YK43Y/ZZYP
Specification：
DN15~300mm
Pressure：
1.6~32Mpa
Material：
Cast steel, forged steel, stainless steel, forged stainless steel, copper

Gas pressure reducing valve is an automatic pressure regulating valve used in gas medium pipelines. Its core function is to accurately reduce and stabilize the high and unstable pressure of the gas source (such as steel cylinders, storage tanks, or main pipelines) at the required, lower, and constant working pressure of the equipment. According to its working principle, it is mainly divided into direct acting type (simple structure, suitable for small flow and low precision requirements) and pilot type (high precision, good voltage stabilization performance, suitable for large flow, high pressure difference or high-precision control applications). It senses changes in outlet pressure internally through sensitive components such as diaphragms and pistons, and automatically adjusts the valve disc opening to maintain the set pressure. Kaiweixi Valve Group mainly produces gas pressure reducing valves such as air pressure reducing valves, nitrogen pressure reducing valves, oxygen pressure reducing valves, argon pressure reducing valves, corrosive gas pressure reducing valves, marine gas pressure reducing valves, helium pressure reducing valves, inert gas pressure reducing valves, etc. Gas pressure reducing valves are key components in industrial production, laboratories, and medical fields, widely used in welding and cutting, chemical production, instrument gas supply, respiratory equipment, gas analysis, and fuel cell systems.
