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 have an optional 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.
