The Wafer Check Valve, or pinch check valve, is a valve used to prevent the reverse flow of fluid. The following is a brief introduction to pinch check valves in Chinese:

Valve Types and terms: Pinch check valves are a common type of valve, often used in piping systems to prevent media backflow.

Function of the check valve: The main role of the check valve is to allow one-way flow of the medium and prevent reverse flow. For example, Coreline Fig.614,615 double-clamp thin check valves are designed for installation in piping systems that allow media to flow in only one direction and prevent media backflow.

Installation and operation: The clamp check valve needs to pay special attention to safety and operation specifications during installation. For example, Coreline's installation operations manual notes that valves need to be pressure tested and follow safety recommendations when installed into the piping system.

Maintenance and disassembly: The clamp check valve also needs regular maintenance and inspection during use. For example, when removing a valve, you need to check that the pipe is disconnected, empty, and under normal pressure, then remove the flange bolts, and then use a tool to separate the flange.

Application: Pinch check valves are widely used in various industrial fields, including but not limited to petroleum, chemical, food processing, etc. They are designed and manufactured to meet specific industry standards and certifications, such as ATEX and CE certification.

Product features: Some pinch check valves may have special designs, such as spring-free or spring-loaded, to suit different application requirements.

Safety precautions: When using the clamp check valve, it is necessary to follow the safety instructions and operating manuals provided by the manufacturer to ensure the normal operation and safety of the valve.
