PRODUCT DATA

Application

Lancevalves are used to connect radiators to one- or twopipe heating systems. Separable connections under the floor are avoided. Vertical lancevalves are often used for design radiators and bathroom radiators.

The Asymmetrical Lancevalve is suitable for all Honeywell thermostatic heads and all other thermostatic heads with M30 x 1.5 connection and 11,5 mm closing dimension. Further for Honeywell and other actuators with M30 x 1.5 connection and 11,5 mm closing dimension.

Features

• Suitable for both one- and two-pipe systems, for wall

and floor connection

• Separate connections for supply and return

• Separate valve inserts for supply and return:

• Thermostatic valve insert with flat cartridge in the

supply, suitable for one- ond two-pipe systems

• Pre-settable valve insert for one-pipe operation with

0–47% radiator proportion or for two-pipe operation (100% radiator proportion) in the return

• Pipe distance 40 mm

• Radiator lance, length 130 mm

• Low noise

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.
