Greater CV Potential & Less Pipe Space
TTV butterfly valves feature a refined disc profile that delivers a significantly higher flow coefficient compared to conventional butterfly valve designs. This results in minimal pressure loss, improved flow efficiency, and lower energy consumption, while still achieving a dependable bi-directional, zero-leakage seal when closed. Reduced operating torque and lower friction levels also help minimise actuator sizing requirements and extend seat service life. Sealing performance is supported by a durable silicone elasticised gasket.
For duties involving abrasive media, this butterfly valve can be supplied with an UHMWPE (Ultra-High-Molecular-Weight Polyethylene) liner, providing enhanced wear resistance and extended operational longevity.
The compact design of these butterfly valves requires less installation space and material, helping to reduce overall system and project costs. In isolation applications, the valve operates via a simple quarter-turn (90°) movement, allowing it to be either fully open or fully closed. When shut, the disc and seat combination ensures complete downstream isolation, while the streamlined metallic disc promotes efficient flow with low pressure loss in the open position.
Beyond on/off service, these valves can also be used for flow, pressure, or temperature regulation when fitted with a multi-position lockable lever or modulating control via 4–20 mA or 3–15 psi signals.
Actuated butterfly valves are available with both pneumatic and electric actuators, making them ideal for remote installations, high-torque applications, or processes requiring precise timing and reliable automation. Pneumatic actuation offers rapid open/close response and is available in double-acting or spring-return configurations, with options for direct or solenoid operation. Spring-return actuators can be configured for fail-safe closed operation, automatically returning the valve to its safe position in the event of power or air failure, with fail-safe open options also available on request.
