Clamp-type Check Valve

The Clamp-type Check Valve is an automatic valve that relies on medium pressure to open and close, without the need for manual or external power control. Its unique clamp connection design allows it to be directly installed between two flanges, eliminating the need for complex flange connections and greatly simplifying the installation and disassembly process. Compared with traditional flange check valves, our clamp-type check valve features smaller volume, lighter weight, lower fluid resistance and longer service life, effectively solving the problems of bulky structure, difficult maintenance and high water hammer pressure of traditional valves.

We adhere to international standards such as American API, German DIN, ISO and 3A in production, ensuring that each product meets strict quality requirements and can adapt to various harsh working environments. Whether it is high-pressure, high-temperature, corrosive media or sanitary-grade fluid systems, our clamp-type check valve can provide stable and reliable anti-backflow protection.

1.Compact & Lightweight Design : The structural length is only 1/4 to 1/8 of that of traditional flange check valves, and the weight is only 1/4 to 1/20 of traditional ones. It saves installation space and reduces transportation and installation costs, especially suitable for narrow-space pipeline layouts such as high-rise building pump rooms and compact equipment cabins.

2.Easy Installation & Maintenance : Clamp connection allows quick installation and disassembly without professional tools. It can be installed on both horizontal and vertical pipelines, with no restrictions on installation direction, greatly improving construction efficiency. The simple and compact overall structure also facilitates daily inspection and maintenance, reducing downtime cost.

3.Low Water Hammer Pressure & Quiet Operation : The valve disc has a short stroke and is equipped with a spring-assisted closing structure, which can quickly close before medium backflow, effectively reducing water hammer impact and avoiding damage to pipelines and equipment. The smooth closing action also reduces operating noise, making it suitable for noise-sensitive environments such as residential areas and food processing workshops.

4.Excellent Sealing Performance : The valve disc and valve seat adopt precision processing and matching, and can be equipped with EPDM, PTFE, NBR or FPM (Viton) seals according to different working conditions. It ensures tight sealing without leakage, even in high-pressure and corrosive media environments, and meets the hygiene requirements of food, pharmaceutical and biotech industries.

5.Unobstructed Flow Path & Low Resistance : The internal flow path is designed to be smooth, minimizing fluid resistance, reducing energy consumption of the pipeline system, and improving the overall operating efficiency of the system. It is suitable for high-flow pipeline applications such as irrigation, water supply and industrial circulation systems.

6.Durable & High Reliability : The valve body is made of high-quality materials such as carbon steel, stainless steel (304, 316L) and alloy steel, with strong corrosion resistance and wear resistance. The precision-manufactured valve core and spring ensure stable operation for a long time, with a service life far exceeding that of ordinary check valves. It has been widely recognized by users in various industries after years of practical application.

- Petrochemical & Metallurgy Industry : Used in oil pipelines, chemical reaction vessels, and metallurgical fluid systems to prevent backflow of corrosive media and protect pumps, valves and other equipment from damage.

- Food & Pharmaceutical Industry : Sanitary-grade clamp-type check valves (316L material, FDA-compliant seals) are used in food processing, beverage, dairy, pharmaceutical and biotech pipelines to ensure medium purity, avoid cross-contamination, and meet CIP/SIP cleaning and sterilization requirements.

- Water Treatment & Municipal Engineering : Applied in water supply and drainage systems, sewage treatment plants, and irrigation systems to prevent backflow of sewage and ensure the safety of drinking water and irrigation water. It is also suitable for fire systems in large commercial complexes, with compact structure and low noise.

- Power & Light Industry : Used in thermal power plant steam pipelines, boiler feed water systems, and light industry production lines to ensure stable operation of the system and reduce energy loss caused by backflow.

- Other Fields : Suitable for mining, oil drilling, marine equipment, and agricultural irrigation systems. It can be customized according to special working conditions such as high pressure, high temperature, and strong corrosion to meet diverse application needs.
