DKR, IDR Butterfly valves

Butterfly valves
Butterfly valve DKR is designed to adjust volumes of hot air andflue gas on various appliances and flue gas lines. It can be usedfor a control ratio of up to 1:10. DKR..F: With the mountedactuator IC 50, butterfly valve DKR..F is suitable for regulatingflow rates for modulating-controlled or stage-controlledcombustion processes. DKR..H: On butterfly valve DKR..H, flowrates can be set and fixed using a lever, for example to limit thehigh-fire rate on the burner. A scale indicates the set angle ofopening. IDR: DKR with actuator IC 50 Pre-assembledcombinations of actuator IC 50, attachment set and butterflyvalve DKR are available as models IDR up to nominal size DN300. IDR is designed for applications with high torques of up to30 Nm. The direction of rotation of the valve disc can beswitched. The valve disc position can be read from the outsidewhereby the direction of rotation is indicated using a colourcode. Depending on the application, the actuator can bealigned to the butterfly valve using various attachment sets.
