DFT Inc., an industry leader in the manufacturing of check valves for more than 70 years, proudly announces the release of its new BNC™ Check Valve, a nozzle-style, axial-flow check valve specifically designed to excel in high-pressure applications.
Many natural gas companies and other industries are now placing their pipelines below ground and are looking for a one-piece valve they can weld in and bury. The BNC™ Check Valve answers that demand with a precision nozzle-style valve that uses axial-flow technology to eliminate turbulence and prevent erosion and vibration. This design reduces downtime and maintenance costs and boosts capacity and accuracy.
Additionally, this valve provides a critical service to the power industry because the valve’s one piece body eliminates leak paths, while providing tight shut off.
This valve is a spring-assisted, center-guided, non-slam check valve. It has an in-line globe-style body with butt weld ends, with the seat integral to the valve body.
The one-piece valve is designed for long life and a no maintenance required design.
The design meets API 6D and ASME B16.34, and its testing meets MSS SP-61 and API 598 (shell and seat). The valve is available in 10″ to 24″ line sizes, and it is constructed of A216-grade WCB carbon steel and other alloys per ASME 16.34 by request.
Trim materials are carbon steel and stainless steel with a hard-faced seat and disc. The valve can be installed either horizontally or vertically and is compatible with steam, water, and gaseous media. Custom sizing for the BNC™ Check Valve is available.
