Honeywell Eclipse BV Hot Air Butterfly Valves

The Eclipse butterfly valves use pre-heated combustion air for high-low or modulating air control in combustion applications. They feature cast iron bodies and come with a control arm.

Eclipse butterfly valves can be automated with most types of electric or pneumatic control motors. A slot on the shaft of the valve indicates position of the shutter in both manual and automatic applications. In manual applications shutters can be adjusted by inserting a screwdriver into the slot and turning the shaft.
