The TTV 40W4040 Butterfly Valve features a highly corrosion resistant CF8M stainless steel body and disc material. The can be greatly rewarding for harsh environments and medium requirements where epoxy coated ductile or cast iron would not offer the longevity required to exposed external factors. More commonly used in the chemical and offshore industries this versatile butterfly valve is also seeing a surge in popularity due its competitive pricing. All units come as standard with 3.1 material certification at no additional cost.

Key features and benefits of the 40W4040 Wafer Pattern Butterfly Valves.

Key Features

Generally classed as an economical and general purpose solution the wafer pattern butterfly valve features a single Piece body with four flanged hole drillings for easy maintenance and installation between flanges at desired locations within the pipeline.

Key Features

The concentric design of the butterfly valves allows for an elastic, replaceable seat that takes on both shape and size to form a perfect seal. This TTV Butterfly Valve is suitable for use in either off or throttling applications with no loss of functionality.

Key Features

Our extensive range of stocked butterfly valves enable us to provide many materials. With component form availability we can interchange Disc and Seat materials accordingly giving us flexibility and quick turnaround for sizes.

Wafer lever-gear operated stainless steel butterfly valves are used to control or isolate flow in hygienic, corrosive, or high-moisture environments. They are common in food processing, pharmaceuticals, water treatment, and chemical applications where stainless steel construction is essential for cleanliness and corrosion resistance.

A wafer-style body is compact and lightweight, allowing the valve to fit between flanges without adding extra pipeline length. This design reduces installation space, lowers system weight, and makes it a cost-effective option for many industrial systems.

Stainless steel provides excellent resistance to corrosion, chemicals, and high humidity. It also improves hygiene and durability, making the valve suitable for aggressive media and washdown environments where coated iron valves may degrade over time.

The lever-gear operator reduces the effort required to open or close the valve, especially in larger sizes. It allows controlled, gradual movement of the disc, improving safety and precision while preventing sudden pressure shocks in the pipeline.

Common seat materials include EPDM, PTFE, and NBR, each suited to different temperatures and media. Selecting the correct seat ensures proper sealing performance and extends the valve’s service life in demanding applications.

Yes, they are designed for simple inspection and low maintenance. Regular cycling and occasional seat checks help maintain smooth operation, and stainless steel construction reduces the risk of rust-related failures.

Can wafer lever-gear operated stainless steel butterfly valves be used for throttling?
