● 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 dual plate check valve features two semicircular, spring-loaded valve discs mounted on a central vertical pivot. When the valve opens, the force of the fluid and the spring act at the center of the disc, causing it to open from the base first. This design minimizes wear on the seal during opening, enhancing its durability. As the flow decreases, the discs slowly move back towards the seat due to the spring's force, ensuring a gradual closure. During backflow, the increased force on the discs leads to a faster closure, effectively reducing the risk of water hammer and hydraulic shocks. The spring’s force closes the top end of the disc first, preventing damage at the disc's base and prolonging the seal's lifespan.
This series of products features a compact structure, small size, and S-shaped fluid channels. The valve core adopts a pressure-balancing structure, with high accuracy of the flow characteristic curve and the ability to achieve a larger CV. It can be quickly replaced, is stable and reliable, and is easy to maintain. A smaller actuating force can control a high pressure difference. There is a sealing ring between the valve core and the valve cage, significantly reducing the leakage. It is equipped with the RSMF series multi-spring pneumatic diaphragm actuator, which has a large thrust, strong steel strength, sensitive action, high-precision positioning, fast response, convenient and sturdy, and a long service life.
