Features & Benefits
Easy to operate
DN 15-50 are equipped with a precision control handwheel and allows the balancing valve to be locked to a set value, making the valve easy to adjust. DN 65-150 are equipped with a removable handle that ensures accurate and straightforward balancing. DN 200 and up are equipped with a manual gear.
SELF-SEALING MEASURING POINTS
For simple, accurate balancing.
Steel body
Fully welded body construction is light weight, easy to insulate and maintenance free.
