Electric actuator specialist AUMA has supplied leading British valve manufacturer KOSO Kent Introl with an AUMA SEVEN HiMod variable speed actuator and a large GS gearbox. The AUMA equipment will operate a 48-inch butterfly valve within a flagship new project for Danish utility supplier Hofor, which will transfer the Copenhagen district heating system from steam to hot water.
The butterfly valve is the largest supplied by KOSO, and the AUMA SEVEN HiMod, in conjunction with the GS gearbox, delivers a torque of 90,000Nm. AUMA UK worked closely with KOSO to help design a mounting that allowed the drive shaft of the valve to interface accurately with the AUMA gearbox.
