Belimo butterfly valves and actuators have zero leakage rate

Belimo, butterfly valve, actuator, energy efficiency

Belimo’s new generation of butterfly valves and actuators for high-flow applications for HVAC and commercial applications achieve zero leakage at 200 psi (13.7 bar). These valves have large Cv values to achieve an economical valve solution for larger-flow applications using ANSI flanged piping systems. Typical applications include isolating chillers and boilers, primary bypass flow control, isolating cooling towers, controlling coils in large air-handling units and process-control heat-exchanger applications.

The actuators can be powered by 24 to 240 V AC or 24 to 125 V DC — just one type of actuator. They have a brushless DC motor that uses 80% less power than other actuators to reduce transformer and wiring costs. They are mounted onto the valve using just two bolts and have a running time that is adjustable from 30 to 120 s. An electronic fail-safe option provides security for safety sequences if power is lost. A position indicator can be seen from long distances and any angle.

Thermal isolation in the valves reduces heat transfer to the actuator and avoids the build-up of condensation.

The valves are available in 2-way and 3-way versions in sizes from DN100 to DN250.
