Reliable shut-off with the BOA-H energy-saving valve

• Low heat losses by easy-to-insulate bonnet

• Confined bellows protected from pressure surges

• High operating comfort: Position indicator with travel stop and locking device outside the insulation

• 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)

Benefits

High operating comfort at no extra charge: 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.
