The TTV 20W3040 is a ductile iron butterfly valve with a durable Rilsan-coated body, featuring a CF8M stainless steel disc and a 304 stainless steel shaft. Its concentric one-piece body design includes four locating lugs, allowing for straightforward alignment and installation between two pipeline flanges—even at intermediate points in the system.

Engineered for general-purpose applications, the 20W3040 offers a cost-effective yet reliable solution across various industries. Its solid single-piece shaft enhances structural integrity while providing direct mounting compatibility for electric or pneumatic actuators. The valve also features a dry shaft design, preventing media contact with both the shaft and body for improved corrosion resistance and longer service life.

The TTV 50W3040 is a carbon steel butterfly valve featuring a Rilsan-coated WCB body, a CF8M stainless steel disc, and a 304 stainless steel shaft. This robust concentric design incorporates a one-piece body with four lug-style mounting points, allowing for straightforward installation between two flanges—even at intermediate positions along the pipeline.

Built to handle more demanding applications compared to the 20W3040 model, this valve is ideal for both on/off isolation and modulating control. Its quarter-turn operation ensures fast, reliable actuation, while the streamlined flow path offers excellent flow characteristics. When fully open, the only flow resistance comes from the disc’s profile—resulting in minimal pressure drop across the valve.

The 40W4040 Stainless Steel Butterfly Valve range from Actuation Valve delivers dependable shutoff and corrosion resistance for both internal and external aggressive environments. Constructed with a durable stainless steel body and a replaceable concentric rubber-lined seat, this valve is built to last in even the harshest conditions.

Whether you're seeking a manual lever-operated solution or require a multi-turn gear-operated package, we offer a selection of worm gear and chain wheel configurations to meet your operational needs. Engineered entirely from stainless steel components, this valve range is ideally suited for applications across the food & beverage, chemical, and petrochemical industries—where hygiene, durability, and corrosion resistance are essential.

Designed for highly corrosive media and elevated service temperatures, the 20WP4040F0T PTFE-Lined Butterfly Valve features a wafer pattern split-body design with four flange hole drillings for straightforward installation and maintenance. Its compact, lightweight form factor makes it ideal for pipeline systems where space and weight are limited.

The fully encapsulated PTFE seat ensures maximum chemical resistance and eliminates the risk of cross-contamination, making it suitable for demanding applications involving acids, solvents, and aggressive fluids—with temperature resistance up to 300°C. For environments requiring greater abrasion resistance, an alternative UHMWPE seat is also available.

The Colossus High-Performance Butterfly Valve range is built to withstand extreme operating conditions, offering critical shutoff and precise throttling control for both gas and liquid applications. Engineered for durability, the series includes Double Eccentric Metal Seated, Double Eccentric PTFE Seated, and Triple Eccentric Metal Seated designs.

These firesafe-rated valves are increasingly chosen as a superior alternative to traditional Gate, Globe, and Ball Valves—particularly in high-pressure or high-temperature environments. With double offset construction, they are capable of handling higher operating pressures while minimising seat wear and improving service life.

The 80LM580 Aluminium Bronze Butterfly Valve builds on the proven performance of the 80LK8N and TTV-ABABM ranges, offering a reliable solution specifically designed for seawater and harsh marine environments. Aluminium Bronze is highly regarded for its exceptional corrosion resistance, making it the go-to choice for systems exposed to saltwater, brackish conditions, and offshore elements.

With long-term material stability, these valves are widely used across fire protection systems, potable water lines, cooling circuits, ballast control, and HVAC installations. Actuation Valve has a strong track record supplying Aluminium Bronze valves to the Marine and Offshore industries, delivering robust performance in some of the most demanding and remote operating environments.

The 20W3080 Bronze Disc Butterfly Valve is engineered for performance in marine, chemical, and petrochemical applications, offering dependable protection against corrosive media while maintaining cost-efficiency in environments with less aggressive external conditions.

Fitted with a B148 Aluminium Bronze disc, this valve delivers long-term durability and corrosion resistance, making it a trusted choice for demanding flow control tasks. The concentric body design includes a replaceable seat that conforms to both sides of the disc, ensuring a reliable, bubble-tight seal for both on/off and throttling
