Mikrotherm
Manual radiator valves with presetting
The Mikrotherm manual radiator valve is used in warm water pump heating systems, gravity or low pressure steam systems. The non-rising double spindle with the Mikrotherm presetting cone makes hydraulic balancing through presetting possible.
Features & Benefits
Body made of nickel-plated corrosion-free gunmetal
Double O-ring sealing (DN 10 – DN 25)
With presetting
Can be retrofitted as a thermostatic valve
