PTFE Seat Lugged Air Torque Actuated Butterfly Valves

The TTV PTFE Lined and PTFE Seat Actuated Butterfly Valves are mainly used for highly corrosive applications that require optimum material resistance as well as clean or food grade requirements. The TTV PTFE material is approved by FDA. 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. Optional Hand-polished, streamlined discs produce a much greater CV than other butterfly valves on the market which leads to low pressure drops and reduced energy costs. In addition they maintain a bi-directional bubble tight seal in their closed position.

Frequent Interrogation

A PTFE Seat Lugged Air Torque Actuated Butterfly Valve is a quarter-turn valve designed for automated flow control. It combines a chemically resistant PTFE seat with a durable lugged body and an Air Torque pneumatic actuator for smooth, reliable operation.

PTFE provides outstanding resistance to chemicals, solvents, and corrosion. It remains fully stable and insoluble up to 300°C, ensuring a tight seal even in aggressive or high-temperature environments.

The lugged pattern allows bolting on both sides of the valve, enabling one side of the pipeline to be removed without disturbing the other. This makes it perfect for isolation, maintenance, and end-of-line applications.

Air Torque pneumatic actuators offer high torque output, long service life, and consistent performance. Their rack and pinion design provides reliable automation for both on/off and modulating control duties.

Yes. The PTFE seat ensures compatibility with a wide range of aggressive fluids, making them ideal for chemical processing, pharmaceuticals, food production, and water treatment systems.

Yes. Air Torque actuators are available with ATEX-certified options, allowing safe use in hazardous or explosive areas when combined with suitable accessories like solenoid valves and switchboxes.

These valves typically operate up to PN16 / ANSI 150 pressure ratings, with temperature ranges from -40°C to +200°C, depending on seat and seal materials.

The valve and actuator are connected via an ISO 5211 mounting interface, ensuring a precise fit and easy replacement or upgrade without modification.

Maintenance is minimal. Periodic checks of the seat, shaft seals, and actuator function ensure continued performance. The PTFE seat’s self-lubricating properties help reduce wear.

Yes. With an Air Torque actuator and the appropriate positioner, these valves can be used for accurate modulating control, not just simple open/close operation.

Non Toxic FDA Approved PTFE

Wafer Pattern concentric design features a non-toxic PTFE internal seal which also partially covers the outer body of the valve for perfect sealing with counter flanges. Thus avoiding any possibility of cross-contamination and providing a butterfly valve that is extremely resistant to chemicals and solvents with complete insolubility to 300°C.

Engineered Shaft Design

A single piece shaft design brings high strength and stability with direct mount capabilities for actuation assemblies and ensures fluid is again isolated from both the shaft and the body of the butterfly valve. This also eliminates the need for a customised mounting assembly kit which can bring additional costs and time.

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.
