The Bäst replacement inserts replace the inserts in the Bäst system valves. The Bäst valve has been manufactured in some 50 different designs.
The replacement insert is regulated with a thermostatic head, thermal actuator or handwheel.
NOTE! Not with maximum limit thermostatic heads.
All Bäst valve models have a universal securing nut that is fitted to an external threaded valve housing. Many also have a pre-setting dial, stamped plate and handle to open and close the valve.
NOTE!! For satisfactory function, existing valve housings should be undamaged and the following instructions must be followed. Functionality cannot be guaranteed due to deviating valve designs, incorrect installation, poor heating capacity or other circumstances that are beyond our control.
