Key features and benefits of the 50W3040 Wafer Pattern Butterfly Valves.

Key Features

Our extensive range of stocked butterfly valves enables us to provide many materials. With component form availability we can interchange Disc and Seat components accordingly giving you the flexibility for sizes, as well quick turnaround time on orders regardless if it's large or small.

Key Features

During the closing movement, the rate of cut-off of the flow diminishes as the disk moves towards the closed position, making the valve well suited for flow regulation purposes. An extensive range of synthetic elastomers provide Positive shut-off with repeatability of performance.

Key Features

TTV Butterfly Valves concentric design features an elastic, replaceable seat that takes the shape of both the inside and partially outer side of the body of the valve to form a perfect seal. This TTV Butterfly Valve is suitable for both on and off or throttling applications.

They are commonly used in water treatment, HVAC systems, general industrial processes, and other applications where a robust, cost-effective flow control solution is required.

A wafer butterfly valve is designed to fit between two flanges in a pipeline. The compact body is held in place by flange bolts, making installation quick and space-efficient.

Carbon steel offers higher strength and durability compared to lighter materials, making it suitable for more demanding industrial applications where pressure and mechanical stress are greater.

The 50W3040 offers a more robust construction with a carbon steel body, making it better suited for higher pressure and more demanding applications where durability is critical.

Rilsan is a protective nylon-based coating that enhances corrosion resistance and extends the life of the valve, especially in aggressive or exposed environments.

The 304 stainless steel shaft provides strength and corrosion resistance, ensuring reliable operation and long-term durability under repeated use.

Yes. The Rilsan coating provides added protection against environmental factors such as moisture and corrosion, making it suitable for outdoor installations when properly specified.

In a concentric design, the disc and shaft are centrally aligned within the valve body. This creates a simple, cost-effective solution suitable for general-purpose applications.

This design improves strength and alignment during installation, ensuring the valve is securely positioned between flanges and reducing the risk of movement or leakage.

It certainly does. All of our TTV butterfly valves come complete with a full set of operations and maintenance manuals. We can also send this electronically in advance.
