The TTV Butterfly Valve, with its concentric design and replaceable seat that takes the shape of both sides to form a perfect seal. This is suitable for use on either an off or throttle setting in applications where you want complete flexibility for temperature or flow. Bronze butterfly valves are an excellent solution if you require a valve that will function properly even when exposed to corrosive media such as seawater or brackish water. These bronze disc valves offer maximum protection against erosion from aggressive liquids like saltwater. The TTV range of bronze disc butterfly valves come with approvals from recognised bodies such as DNV, ABS, LR and Bureau Veritas. The bronze disc valves are commonly used in oil and gas processing plants as well as marine.

A lugged butterfly valve has threaded inserts at both sides of the valve body, allowing it to be bolted directly between flanges for secure and stable installation — even in end-of-line service.

Bronze discs provide excellent corrosion resistance, especially in marine and offshore environments where seawater or brackish water is present. They also reduce erosion from aggressive fluids.

Yes. Thanks to the TTV valve’s concentric design and replaceable seat, it can function efficiently in both throttling and shut-off applications.

TTV bronze disc butterfly valves use a replaceable seat that conforms to both sides of the disc, creating a tight and reliable seal under various conditions.

Yes. TTV bronze disc butterfly valves carry marine certifications from DNV, ABS, LR, and Bureau Veritas, making them ideal for shipbuilding and offshore applications.

These valves are widely used in oil & gas processing plants, marine vessels, shipbuilding, desalination systems, and other corrosive media applications.

Yes. With an ISO 5211 mounting pad, they are compatible with electric or pneumatic actuators, though lever and gear options are also available for manual operation.

The TTV lugged bronze disc butterfly valves are available in a wide range of sizes, typically from DN50 up to DN600, depending on the specific model.

The lugged pattern allows the valve to be installed at the end of a pipeline without the need for downstream flanging, and it simplifies isolation for maintenance purposes.

Absolutely. The bronze disc combined with the appropriate seat material provides strong resistance against saltwater and other corrosive agents, ensuring a long service life.

These valves are designed to operate in a variety of temperatures depending on the seat material used, making them suitable for both chilled and heated media.

Depending on the configuration, some seat materials used in TTV bronze disc valves may have WRAS approval. This should be confirmed per model and seat selection.
