BOA-H PN16&PN25

Product benefits

• High operating comfort at no extra charge due to position indicator with travel stop and locking device outside the insulation. Valve disc position can be checked at any time.
• Optimum start-up and throttling due to standard throttling plug up to DN 100 (seat-guided V-port plug optionally available for all valve sizes to meet maximum throttling requirements).
• When the valve is fully open, the bellows is confined within the valve body, protected from pressure surges.
• Little heat loss during operation due to short and smooth bonnet suitable for easy and cheap insulation.
• Added protection against fatigue fracture: The bellows is welded to the stem, so no vibrations are transmitted from the valve disc to the bellows.
• Back-up gland packing provides additional safety in case of defective bellows.
• Position indicator with colour coding system for identification of valve design during replacement work. The disc type and seat/disc interface material can be verified without removing the insulation.
• Space-saving non-rising handwheel.
