The flanged construction eliminates the need for pipe unions. A unique “O”-Ring seal prevents leakage around the shaft. The valve crank rotates through an 80° arc. Disc position is indicated by the crank arm pointer relative to the valve nameplate scale. The motor mounting base is predrilled for Honeywell, Barber Colman, and Leeds & Northrup control motors. The valves may be mounted either horizontal or vertical.
Modulating motors generally require that the shaft be horizontal. The motor should be wired according to the manufacturer’s installation instructions so that proper rotation is achieved. Limit switches on modulating motors should be used to limit stroke.
The BV-CMAP includes the butterfly valve, motor mounting brackets, valve crank arm, and an adjustable linkage rod.
