Description
Main Applications
– Hot-water heating systems
– Air-conditioning systems
– Boiler feed applications
– Boiler recirculation
– Chemical industry
– Process engineering
– Heat recovery systems
– Sugar industry -
Advantages
– 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.
– Little heat loss during operation due to short and even bonnet suitable for easy and inexpensive insulation.
– Added protection against fatigue fracture: The bellows is welded to the stem, so no vibrations are transmitted from the valve disc.
– Back-up gland packing provides additional safety in case of defective bellows.
– Colour coding 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.
– Reduced maintenance costs due to replaceable valve disc. Instead of replacing the complete upper section, only the valve disc is replaced if necessary. -
