Casting Body Lug Type Double Disc Swing Check Valve

Water Pumping Stations and Water Supply Systems: Protects main pumps and allows for quick, safe replacement or maintenance of individual pumps without the need to drain the entire system.

Industrial Process Lines: Installed at the inlets and outlets of process equipment (reactors, filters, mixers) that require regular cleaning, replacement, or repair.

Marine and Offshore Engineering: Ideal for compact spaces and demanding maintenance conditions; the lug design facilitates safe equipment disassembly in confined engine rooms.

HVAC Systems: Used in large chiller units and heat exchanger loops for convenient seasonal equipment maintenance and isolation.

Any application requiring the combination of "check valve functionality" and a "maintenance isolation point."

Choose the Standard Wafer Type: When the pipeline itself is well-supported, and the valve location does not need to serve as a frequently disassembled equipment interface, the standard wafer type is the most economical and lightweight option.

Choose the Standard Lug Type : When the valve is directly installed on the flange of equipment that requires frequent maintenance, and you want the valve to remain securely fixed on the main pipeline side as an isolation barrier during equipment disassembly, the lug type is the necessary and only safe choice. It is not just a valve but a functional safety node in the system design.
