DFT Inc., the manufacturer of non-slam axial flow check valves, proudly announces the release of its new TLW® Check Valve. The TLW® is a Tapped Lug Wafer style silent check valve specifically designed for use in horizontal and vertical installations for liquid, gas, and steam applications where exposed bolts are not suitable.
This check valve was designed for use in a refining industry application but is relevant for any industry where bolts are required not be exposed to fire or corrosion. As with all other DFT check valves, this silent check valve reduces the potential for reverse flow and water hammer and is designed for long life and low maintenance.
The TLW® is a spring-assisted, center-guided check valve with a lightweight compact wafer-style design (fits between mating flanges), meets API 594 face-to-face dimensions, and its testing meets MSS SP-61 and API 598 (shell and seat). The valve is available in 2″ to 24″ line sizes, and it is constructed of A216-grade WCB carbon steel or A 351 CF8M stainless steel. Other alloys per ASME 16.34 are available by request.
Standard trim materials include a stainless steel seat, disc, and bushing (optional soft seat seal available). The valve can be installed either horizontally or vertically and is compatible with steam, water, and gaseous media. Custom sizing is available for low flow applications.
