Belimo, a leading global manufacturer of innovative electrical actuator solutions in heating, ventilation and air conditioning systems, is offering new butterfly valves from the D6..N range for standard applications that fit in all open/closed shut-off applications for heating and cooling circuits.

The butterfly valves can easily withstand extreme medium temperatures of between –20°C and +120°C (130°C /1h for brief periods) and feature a resistant epoxy coating and stainless valve disc. The tight-sealing shut-off valve also helps prevent energy losses. Since pressure classes PN 6/10/16 are integrated in the flange dimensions, stock keeping is reduced. The high level of material and production quality lends the D6..N butterfly valves a long service life – they will function reliably for many years without the need for any maintenance.

The consistent range covers nominal widths of between DN 25 and DN 350 with flow rates (kvs values) from 45 to 10’900 m3/h. Levers or worm gears are available for manual operations and various electrical Belimo actuators can be selected for motorised opening and closing. It is easy to upgrade from manual lever to motorised actuator, reveals the company’s press release.
