ASYMMETRICAL LANCEVALVE (V2281)

Function
The Asymmetrical Lancevalve distributes the heating water through the lance into the radiator. When the heating water has run through the radiator it flows past the lance and is diverted through the return port of the valve back into the heating circuit. The radiator can be separated from the heating circuit by closing both the thermostatic cartridge and the return cartridge of the Asymmetrical Lancevalve. Radiators further down the line are not affected by this.
