Greater CV Potential & Less Pipe Space
TTV butterfly valves utilise a refined disc profile that delivers a higher flow coefficient (Cv) than many comparable butterfly valves, reducing pressure loss and helping to lower overall energy consumption. Despite this improved flow performance, the valve maintains a tight bi-directional seal when closed, ensuring dependable zero-leakage isolation. Reduced friction across the sealing surfaces results in lower operating torque, which in turn decreases the size and cost of gearboxes, pneumatic actuators, and electric actuators while extending seal service life. Valve sealing is supported by a durable silicone-based elastomer gasket.
For duties where increased wear resistance is required, an optional UHMWPE (Ultra-High-Molecular-Weight Polyethylene) liner can be specified, offering enhanced protection in abrasive service conditions.
The compact design of these butterfly valves requires less installation space and reduced material usage, contributing to lower overall system costs. In isolation applications, the valve operates via a simple quarter-turn (90°) action using either a manual lever or actuator, moving fully from open to closed with minimal effort. In the closed position, the disc and seat provide reliable, leak-tight shut-off, while the streamlined metallic disc minimises pressure drop when the valve is open, supporting efficient fluid flow.
Beyond isolation, these butterfly valves can also be used for basic flow, pressure, or temperature regulation when fitted with a multi-position locking lever or control accessories such as 4–20 mA or 3–15 psi actuation systems.
Actuated butterfly valves are available with both pneumatic and electric operation, making them well suited for remote locations, high-torque applications, and processes requiring accurate timing or synchronised control.
