● The dual-plate wafer check valve consists of a valve body, discs, shaft, and springs, featuring a wafer-style connection for a compact structure.
● The butterfly plates are two semicircles, using spring-forced resetting. The sealing surfaces can be made from wear-resistant material welded onto the body or lined with rubber, offering a wide range of applications and reliable sealing.
● The closing stroke of the valve disc is short, and it is spring-loaded for quick closure, which can significantly reduce water hammer phenomena.
● Suitable for installations in spaces with limited access; it can be used in both horizontal and vertical pipelines and is easy to install.
● Applicable for various mediums including water, steam, oil products, nitric acid, acetic acid, and strong oxidizing agents.
● The product features a small size, light weight, sensitive action, reliable sealing, easy installation, and a long service life.

CHM703 High Pressure Control Valve is a high-precision fluid control device specially designed for harsh industrial environments. It is suitable for high-pressure pipeline systems in industries such as petroleum, chemical engineering, power, and metallurgy. This product uses high-quality materials and advanced manufacturing techniques to ensure stable operation even under extreme conditions such as high pressure, high temperature, and strong corrosion. Its compact structure and reliable sealing enable precise regulation of flow and pressure, meeting the strict requirements of complex industrial processes. The high-pressure regulating valve has excellent shock resistance and vibration resistance, and is suitable for frequent opening and closing and high-load operation environments. It is also easy to maintain, effectively reducing long-term usage costs, making it an ideal choice in the field of industrial fluid control.
The Lifting Plug Valve adopts a unique dual-action design of lifting and rotation. When opening, it first lifts and then rotates to achieve zero-friction operation. It is particularly suitable for high-pressure difference, easily crystallizing and media containing solid particles. The valve body and the plug are both precisely ground, and the self-cleaning sealing surface design ensures reliable sealing performance under harsh conditions. It is widely used in high-parameter working conditions in the petroleum, chemical and power industries.
Oxygen Globe Valve are often used in physical and chemical experiments with gases such as oxygen, nitrogen, hydrogen, argon, etc. These gases are usually stored in dedicated high-pressure gases. When in use, the gas pressure is reduced to the required range for the experiment through a pressure reducing valve, and then finely adjusted through other control valves to input the gas into the system. The oxygen shut-off valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak.
