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.

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.

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.

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

The valve is suitable for almost all chemical applications. Send in an email of pick up the phone. One of our super tech guys will check it over for you.

We can. The final is prodcut customizable 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.

Maybe. Give us a call to find out.

No. Why do people keep asking!? We are not the silly pink valve company.

Most definitely. We will require some more information. Drop us an email or get in touch on the blower.

Yes we can. Plane label or with a big bow. Send us a copy of your delivery note and we will fix it to the box. Job done.

We will need to talk to Big Tony. If he says you're good for the debt then everything is in order. You can apply for this on the product page or ask for Big Tony when you get in touch.
Collections are welcomed. Give us a call in advance and we can get you a time that suits.

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.
