The TTV 20W3080 bronze disc Butterfly Valves can be used as an economical and cost effective solution non external corrosive environments. This particular model from Spanish manufacturer TTV is commonly used for seawater isolation requirements and offers a dry shaft design preventing contact between the liquid and valve body. Other common applications include natural gas utilising the NBR buna soft seat with yellow valve lever handle for immediate visual indication of what is flowing through the pipeline.

Key features and benefits of the 20W3080 Wafer Pattern Butterfly Valves.

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

The streamlined design allows for very low pressure drops making them ideal for commercial applications where energy costs need to be kept as low as possible. Their compact size makes them perfect for situations where space is limited.

Key Features

Typical application requirements for our bronze butterfly valves include Firewater and Sprinkler Systems, Potable Water, Sea Water Injection, Ballast, Sewage Treatment, Cooling Water, HVAC and Shipside Valves.

Yes, this Valve is suitable for sea water within the pressure and temperature limitations.

Yes. We have a number of options including chain wheel operators. They come as standard with a quick link chain connection and safety cable kit.

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.

It is a wafer-style butterfly valve installed between flanges, operated manually by a lever or gearbox, with a bronze disc for improved corrosion resistance.

Wafer valves are compact, lightweight, and cost-effective, making them easy to install in systems with limited space.

Gear operation is used on larger valves or higher torque applications, making the valve easier to operate and control.

Yes — bronze disc butterfly valves are commonly used in water systems due to their corrosion resistance.

Yes — they are suitable for both flow regulation and shut-off applications.

They are widely used in water treatment, marine, HVAC, and general industrial systems.

Common seat materials include EPDM, NBR, and PTFE, allowing compatibility with different media and temperatures.
