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

It’s a stainless steel wafer-pattern butterfly valve featuring a PTFE seat for chemical resistance, powered by an Elomatic pneumatic actuator for precise automated flow control.

PTFE provides excellent resistance to corrosive media, low friction for smooth disc movement, and a non-contaminating sealing surface ideal for aggressive or high-purity applications.

Stainless steel delivers superior durability, corrosion resistance, and suitability for harsh environments such as chemical processing, water treatment, and food-grade systems.

Elomatic actuators are engineered for long life with a robust rack-and-pinion design, consistent torque output, minimal maintenance, and smooth, dependable operation.

Yes. With the correct accessories, the Elomatic actuator can perform standard on/off operation or provide accurate modulating control.

Absolutely. The combination of stainless steel and PTFE makes it suitable for solvents, acids, and chemical media commonly used in industrial processes.

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

The wafer configuration offers a compact, lightweight installation between flanges and provides secure sealing with fewer bolts compared to lugged designs.

Maintenance is minimal. Routine checks include inspecting seals, ensuring actuator lubrication, and verifying electrical/pneumatic connections for consistent performance.

Yes. When installed between two flanges, the valve provides reliable pipeline isolation for maintenance or process control.

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 provides the butterfly valve with excellent strength and stability while enabling direct mounting for actuation assemblies. This setup ensures the process fluid is fully isolated from both the shaft and the valve body — a level of protection often compared to the sealing integrity of a high-quality ball valve. With no need for a customised mounting kit, installation becomes quicker, simpler, and more cost-effective.

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.
