20WP4040F0T Lever-Gear Operated Butterfly Valves

The TTV 20WP4040F0T manually operated Butterfly Valve features a zero leakage bi-directional seal from a concentric design. The non toxic PTFE seat and coated disc are FDA approved and suitable not only for high chemical resistance applications but also food and beverage, pharmaceutical and consumer health manufacturing applications. The wafer body design offers the perfect isolation solution with guide lugs assisting installation. Additional features for more abrasive applications include UHMWPE.

Key Features

Key features and benefits of the 20WP4040F0T Wafer Pattern Butterfly Valves.
1

Key Features

The TTV PTFE range of butterfly valves feature a state of the art design from years of research and development with corrosive and aggressive chemical manufacturers as well as food and beverage. The bubble tight shutoff provides complete isolation when you need it most.
2

Key Features

The PTFE Butterfly Valve features a non-toxic PTFE seal that also partially covers the outer body of the valve for perfect sealing with counter flanges. This makes them ideal for use in highly corrosive environments and higher service temperatures where traditional materials fail.

Key Features

The High Performance Wafer Pattern PTFE Butterfly Valve is a high-temperature, chemical resistant valve that can handle extreme conditions. The internal seal of this unit consists of non-toxic and durable material.

Top Notch.

All Butterfly Valves come as standard with a Top Notch Lock Plate. Adjustable at set degrees throughout the Valve travel cycle. Are your current supplies as good? We very much doubt it.

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.

Great. That would be in our actuated butterfly valve section! Have a look over there or get us on 0151 547 1221. We have what you need.

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.
