Pressure Reducing Valve Manufacturer in China
When the downstream pressure of the pressure-reducing valve exceeds the set value, the pressure will be reduced. No matter how the inlet pressure fluctuates, the valve will automatically close and output a stable outlet pressure. No matter how the downstream flow changes, the outlet pressure can be kept at the set value of the pilot valve. In short, this product is very suitable for household water supply.
Fire protection system and industrial water supply system. The pressure-reducing valve is mainly suitable for water, fire protection systems, etc.
Liangzheng was established in 2003 and has Changzhou Gas Valve Production Base and Binhai General Valve Production Base. Tianjin Water Control Valve Production Base, Fujian Casting Production Base, etc., with a total area of 100 mu, more than 350 employees, after years of efforts and development, is a valve enterprise integrating scientific research, design, manufacturing, sales and service.
Various Types of Our Pressure Reducing Valve
The working of the steam pressure reducing valve is controlled by the pressure after the valve. When the pressure sensor detects the valve pressure indicator When the pressure rises, the valve opening of the pressure-reducing valve decreases.
The diaphragm of the high-sensitivity pressure-reducing valve uses new materials and has been significantly optimized in the working area to adjust the opening of the main valve and ensure stable downstream pressure.
Pressure Transmission of Pilot-Operated Pressure Reducing Valve
The inlet pressure of the pressure-reducing valve enters the control chamber of the main valve through the conduit and the regulating valve, and produces a downward pressure. The outlet pressure also acts on the diaphragm of the pilot valve and counteracts the regulating spring of the pilot valve through the conduit.

Applications of Our Pressure Reducing Valve
In the rotating mode of the pressure reducing valve, hydraulic operation is adopted, that is, the up and down movement of the main valve is automatically operated by the water pressure in the pipeline, the opening of the control valve is controlled, the downstream pressure is regulated, and the downstream pressure is kept at the pressure value set by the guide valve spring.
The pressure reducing valve is designed and manufactured by our company’s engineering and technical personnel according to the advanced products of the same type at home and abroad. The main body of the reader adopts a full-channel streamlined design, with smaller fluid resistance and larger meteors.
When the downstream pressure exceeds the set value, the pressure reducing valve will automatically close. No matter how the inlet pressure fluctuates, it can output a stable outlet pressure . No matter how the downstream flow changes, it can maintain the outlet pressure stable at the set value of the pilot valve.

This type of pressure reducing valve is composed of a main valve, a pilot valve, a needle valve, a one-way valve, a ball valve, a miniature filter and a pressure gauge. Since the pilot valve, needle valve, and pressure gauge need to be connected to the main valve using a conduit, they are collectively referred to as the conduit control system.
When the downstream pressure of the pressure reducing valve exceeds the set value of the pilot valve spring, the pilot valve closes, the drainage of the control chamber becomes 0, the pressure change reaches the maximum value, and the main valve disc is pressed against the valve seat to close the pressure reducing valve. Once the downstream pressure drops to the set value of the pilot valve spring in the pressure-reducing valve, the pilot valve opens, and the pressure water in the control chamber will be discharged to the downstream through the pilot valve and ball valve.
Some Notes About This Pressure Relief Valve
The pressure reducing valve should be installed horizontally, and the debris in the pipeline should be thoroughly cleaned before installation. Pay attention to the water flow arrow on the main valve body, and follow the direction to install it. After installation, ensure that there is no pipe stress acting on the valve body and internal components.
A gate valve and a filter should be installed before the pressure reducing valve, and a gate valve should also be installed after the pressure-reducing device for easy maintenance.
The pilot valve and pipeline control system in the pressure reducing valve have been assembled and tested in the factory. If the pressure value set by the pilot valve is not suitable for the on-site requirements, it can be adjusted by tightening or loosening the upper screw of the pilot valve. Turning the screw clockwise will increase pressure, while turning it counterclockwise will decrease pressure.
The microfilter should be cleaned regularly.
The pipeline system and pressure reducing valve must be thoroughly flushed before passing.
Bypass valves should be installed on important water supply lines.
