PTFE Lined Wafer Air Torque Actuated Butterfly Valves

A combination of the TTV 20WP4040F0T and Air Torque actuator. Most commonly used amongst the chemical and food or beverage industries this actuated butterfly valve assembly outperforms most others on the market. A rilsan coated body butterfly valve and anodised aluminium actuator provide external protection for most non aggressive external application factors whilst the internal PTFE lining provides superior corrosion resistance as well as an FDA approved contact material for consumable products. A replaceable valve seat and actuator rated to SIL3 complete a robust high performance package that will go the distance and provide maximum life capacity. The Air Torque actuator is in field convertible should you ever require a change from the spring return and double acting functionalities.

Key Features

Key features and benefits of the 20WP4040F0TAT Actuated Butterfly Valves.
1

Key Features

Our air torque actuators are made of high quality materials and have been designed for years of reliable service. However, it doesn't stop there - we also offer our customers with the option to choose from multiple materials including stainless steel or epoxy coated options.
2

Key Features

The High Performance Wafer Pattern PTFE Butterfly Valve can be used in highly corrosive environments as well as higher service temperatures without any issues arising due to its unique design and properties.
3

Key Features

The quarter turn action offers quick opening or closing with ease of operation and the valve has good flow control characteristics. In the wide open position, the only obstruction to flow is that due to the thickness of the disk, so the pressure drop across the valve is small.

Frequent Interrogation

PTFE Lined Wafer Air Torque Actuated Butterfly Valve combines a wafer-style PTFE-lined butterfly valve with a high-performance Air Torque pneumatic actuator. This setup is designed for automated control in chemical, pharmaceutical, and process industries where resistance to corrosive media is essential.

We can. The final is prodcut customisable at the bottom of the page! Have a look down there or get us on 0151 547 1221. We have everything from Safe Area to ATEX in multiple voltages.

It does indeed. Every PTFE butterfly valve we supply is provided with a complete set of manufacturer-issued operation and maintenance manuals.

The wafer design is compact and lightweight, allowing for easy installation between flanges without the need for additional gaskets or bolts. It’s ideal for systems where space and cost efficiency are priorities.

Air Torque pneumatic actuators are Italian-engineered for precision and durability. They deliver high torque output, long service life, and smooth operation, available in both double acting and spring return configurations.

These valves are widely used in chemical processing, water treatment, food production, and pharmaceutical applications, especially where the medium is corrosive or where hygiene is critical.

Typically suitable for temperatures from -20°C to +180°C and pressures up to PN10–PN16, depending on the specific seat and liner material combination.

Yes. When fitted with appropriate accessories such as a positioner or solenoid valve, the Air Torque actuator allows both on/off and proportional (modulating) control options.

PTFE-lined wafer pattern butterfly valves are generally available from DN50 to DN300, with larger sizes manufactured upon request for specific process requirements.

Yes. The full PTFE lining ensures excellent chemical resistance to a wide range of aggressive fluids while maintaining non-contaminating performance for high-purity environments.

Non Toxic FDA Approved PTFE

The wafer-pattern concentric design incorporates a non-toxic PTFE internal seal that extends slightly over the outer body, ensuring a secure and leak-free connection with counter flanges. This design prevents any risk of cross-contamination while offering outstanding resistance to chemicals and solvents, maintaining complete insolubility at temperatures up to 300°C.

Engineered Shaft Design

The single-piece shaft design delivers exceptional strength and stability while allowing direct mounting of actuation assemblies. It also ensures complete isolation of the fluid from both the shaft and valve body, removing the need for a customised mounting kit — saving both time and additional cost.

Streamlined Butterfly Valve Discs

Greater CV Potential & Less Pipe Space

TTV’s streamlined discs produce a much greater Cv than other butterfly valves on the market resulting in low-pressure drops and reduced energy costs while maintaining a bi-directional zero leakage seal when in the closed position. Low operational torque and reduced friction reduces the costs of gear, pneumatic and electric actuation whilst extending the life of the valve seal. A silicone elasticised gasket facilitates the valve sealing. 

For applications which require abrasion resistance the option of a UHMWPE (Ultra-High-Molecular-Weight-Polyethylene) is available for this particular butterfly valve.

Less space, results in less material, bringing significantly lower costs in the process. As part of Isolation applications, our valves can be fully open or fully closed with quarter turn movement (90 Degrees) of the functioning lever or actuator. When closed, the reliable seal and disc can provide 100% leak tight downstream shutoff and low-pressure loss across the valve when opened through a streamlined, energy saving metallic disc. These types of valves can also be used to regulate flow pressure or temperature through a multi-position lockable lever or 4-20mA 3-15 psi control.

Actuated Butterfly Valves are available in both pneumatic and electric operation and can be beneficial for use in remotely accessed areas, valves that require larger torque figures to operate, timing or synchronisation and reliability. Pneumatically Actuated Butterfly Valves provide the quickest form of operational control for open/close functionality and are available in both double acting and spring return units with either direct/solenoid operation. Spring Return units can be set up in a fail-safe closed mode for critical lines were the Valve will return to the closed position upon the event of power failure through the loaded springs. Fail-safe open Valves are also available upon request.
