The KSB globe valve model BOA-H is manufactured according to DIN/EN standards, featuring flanges, bellows, and a straight upper part. It is equipped with a shut-off or throttle cone, a standard position indicator with color coding to distinguish versions, a replaceable cone, and protected bellows when fully open. Sealing surfaces are made of wear- and corrosion-resistant chrome or chrome-nickel steel. Technical data: function shut-off/regulation, flange connection, handwheel drive, housing made of EN-GJL-250 or EN-GJS-400-18-LT, nominal pressure PN 16/25, nominal diameter DN 15 to DN 350, permissible media temperature -10°C to 350°C, housing design as angle or straight valve with flange connection. Advantages include high operating comfort via position indicator with stroke limiter and locking device outside insulation, optimal starting and throttling with standard throttle cone up to DN 100, increased safety against pressure surges by chambered bellows, low heat loss, enhanced vibration break resistance due to welded bellows, additional safety with safety stuffing box, color coding system prevents confusion, space-saving non-rising handwheel, and reduced maintenance costs with replaceable cone.
