Belimo, whose US headquarters are located in Connecticut, recently launched their new generation of butterfly valves and actuators for high-flow applications for HVAC and commercial applications, which are designed to achieve zero leakage at 200 psi (13.7 bar).
Typical applications for these valves 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. They are mounted onto the valve using two bolts and have a running time that is adjustable from 30 to 120 s.
