V2281
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
Dimensions
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.
