PTFE Lined Wafer Elomatic Actuated Butterfly Valves

The High Performance Wafer Pattern PTFE Butterfly Valve has been designed to be in line with the most rigorous safety standards. With an internal seal made of non-toxic and durable material, this unit can withstand extreme conditions whilst meeting FDA approval standards for wetted PTFE parts. The EL-O-Matic Pneumatic Actuator is an affordable alternative to expensive electrically driven actuators that offer the same functionality at a fraction of the cost. They operate significantly faster than electric units of comparable size.

Key Features

Key features and benefits of the 20WP4040F0TEL Actuated Butterfly Valves.
1

Key Features

The split body design on of the PTFE Seat and PTFE Lined Butterfly Valves allow for quick and easy future maintenance requirements. Two body bolts allow the construction to be split into two components with the solid seat design interchangeable within minutes.
2

Key Features

The pneumatic actuators from EL-O-Matic are designed with the highest standards for quality and safety in mind. It has been tested by TÜV SÜD, one of the world's leading testing companies to ensure that it meets all requirements for safe operation.

Actuated Valve Testing & Calibration

All actuated valve assemblies are fully tested and calibrated in house prior to packing and shipping from our expert team of technical engineers. This means that when they arrive at site, you're immediately ready to install and get your production back up and running.

4-20mA Control Available On This Product

The BLX V100E Series is an Electro-Pneumatic control unit that allows the Actuator to incrementally adjust the Valve's position between the fully open and closed cycle. Product variants are available for spring return and double acting setups with feedback and safety settings. Ask our team today about how the V100E can help with your process requirements.

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, a TopWorx limit switch box can be fitted to the Elomatic actuator to indicate the fully open and closed positions electrically. This keeps everything within the Emerson Group of products, with safe area and hazardous area versions available, fitted and calibrated to your actuator before dispatch.

Maybe. Give us a call to find out.

The GJS500-7 ductile iron body is supplied with a Rilsan coating as standard, giving good resistance to corrosion in typical industrial environments. If your application calls for a specific paint finish or additional protective coating, contact our sales team to discuss the options available.

This range is available from DN40 up to DN300, with a 316 stainless steel shaft fitted on DN40-DN200 sizes and an A890 Grade 1B duplex shaft on the larger DN250-DN300 sizes. If you need a size outside this range, contact our sales team with your requirement and we will confirm availability.

Yes, we can arrange drop-shipment straight to your customer's site. Provide the delivery address and any labelling instructions when you place the order, and we can enclose your own delivery note in the package instead of ours if required.

Non Toxic FDA Approved PTFE

The concentric wafer-pattern butterfly valve is fitted with a non-toxic PTFE liner that extends over the valve body, creating a secure seal against the mating flanges. This encapsulated design eliminates the risk of cross-contamination while delivering exceptional resistance to aggressive chemicals and solvents, with proven material stability at temperatures up to 300°C.

Engineered Shaft Design

The butterfly valve features a one-piece shaft construction that delivers enhanced mechanical strength and operational stability. Its direct-mount design allows actuators to be fitted without additional coupling or brackets, while the shaft arrangement prevents media contact with both the shaft and valve body—reducing complexity, installation time, and overall assembly costs.

Streamlined Butterfly Valve Discs

Greater CV Potential & Less Pipe Space

Actuated versions are available with both pneumatic and electric actuation, making them suitable for remote installations, higher torque requirements, and applications demanding precise, reliable operation. Pneumatic actuators offer rapid open/close response and are available in double-acting or spring-return configurations, with direct or solenoid control. Spring-return actuators can be configured to fail closed for critical applications, automatically returning the valve to a safe position in the event of power or air failure, with fail-open configurations also available upon request.

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.
