PTFE Seat Koei UNIC Actuated Electric Butterfly Valves

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. The versatile Koei UNIC electric Actuator is an ideal choice for all your electrical actuating needs and site standardisation with more than 8 individual sizes available we're sure there's one that will fit all of your electric requirements perfectly. At Actuation Valve & Control all of our assembly and testing of actuated butterfly valves is done in-house by our highly skilled team engineers offering Direct Mount, Plate Adaptor & Custom Build Bracket/Shaft Assemblies.

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.

Not in its current format however we can offer both options. Get in touch through sales@actuation.co.uk or 0151 547 1221 and we will run through some safety options with you for quoting.

It certainly does. All of our PTFE butterfly valves come complete with a full set of operations and maintenance manuals from the manufacturer.

Yes! Position feedback is included as standard with switches for open and closed positions.

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.

Fail-Safe Battery Backup

Fail-Safe Battery Backup is available for this product. In the event of a possible power failure the Actuator will return the Valve to a desired position. Ideal for critical line applications where safety is paramount. Will need some additional details from you.
