Overview
Butterfly valves for control ratios up to 10:1, prepared for attachment of an actuator IC 20 or IC 40 and for fitting between two flanges.
Features & Benefits:
Features & Benefits:
- BVA, BVAF for continuous control of an air flow rate
- BVG, BVGF for continuous control of a gas flow rate, BVH, BVHS for continuous or staged control of a hot air or flue gas flow rate
- BVG, BVGF, BVA, BVAF: pu max. 500 mbar, DN 40 to 150, medium temperature: -20 to +60°C
- BVH, BVHS: pu max. 150 mbar, DN 40 to 100, medium temperature: max. +450°C
- BVG, BVA can also be supplied with manual adjustment.BVGF, BVAF work clearance-free and the control command is executed without delay
- BVH, BVHS: in conjunction with the stop bar, the TWINDISC valve disc ensures very low leakage rates
