We can. The final is product 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 certainly does. All of our PTFE butterfly valves come complete with a full set of operations and maintenance manuals from the manufacturer.

Yes we can. If you cant find what you are looking for on the website get in touch. We have valve switch boxes for all zoned and safe areas including LED visual indication.

They are ideal for chemical processing, pharmaceutical, food and beverage, water treatment, and corrosive media applications, where both durability and cleanliness are vital.

The PTFE (Polytetrafluoroethylene) lining provides complete protection to the wetted parts of the valve, ensuring resistance to corrosive chemicals, solvents, and acids, while maintaining low friction for smooth operation.

Air Torque actuators are Italian-engineered for precision, longevity, and torque consistency. They feature compact design, high cycle life, and ISO mounting compatibility, making them a trusted choice for industrial automation.

These valves can be configured as double acting (air to open, air to close) or spring return (air to open, spring to close) for fail-safe operation during air supply loss.

Typically, PTFE-lined stainless steel butterfly valves operate effectively between -20°C and +180°C, depending on the medium and pressure conditions.

They are designed for PN10–PN16 pressure ratings, offering reliable sealing and control performance under moderate pressure systems.

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

The single-piece shaft design offers exceptional strength and stability while allowing direct actuator mounting for simplified automation. It also ensures complete isolation of the process fluid from both the shaft and valve body, eliminating the need for a customised mounting kit—reducing installation time and overall 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.
