Use
The radiator valves are used in hot water heating plants for individual room or zone temperature control and limitation. They are basically recommended in all rooms, especially where heat gains or different temperature levels occur.

Function / mechanical design
The flow rate can be preadjusted with an orifice. Full stroke is ensured irrespective of the preadjustment, which is made with the help of the protective cover.
1 Manual knob / protective cover

Features and benefits
The valves conform to EN 215 The sealing gland can be replaced while the plant is under pressure (no tools
required)

Engineering notes
The reference numbers for preadjustment are given in the table with the kv-values (see page 5) and in the valve sizing charts (see pages 7 � 6).
1. Calculate the volumetric water flow V% 100
. V 100
Q100
[m3/h]
1.163 T f1
Q100 = heat demand
[kW]
T
= temperature differential [K]
1.163 = constant of water
f1
= correction factor = 1 for water
2. Define the pressure drop pv100 across the fully open valve In most types of plant, a differential pressure pv100 of 0.05 to 0.2 bar is adequate.
3. Calculation of the nominal flow value kv

kv 0.052 0.1
= 0.1 bar = 0.17 m3/h
Solution According to the chart (refer to "Valve sizing charts", page 7 or table with kv-values), the preadjustment required by a VDN110 3/8" valve is 2.
Tips Noiseless operation is ensured by a pump that provides no more pressure than is
needed to transport the required amount of water. To keep the valve free from dirt particles, it is recommended to install a strainer.

Setting the kv-values
The kv-values can be set on the valve's head in 5 steps + N (fully open) using the protective cover, which can be turned through 180�.
Observe marking on the valve's outlet side!

The valves are maintenance-free.
In the event of leakage, the valve's sealing gland can be replaced. The valves cannot be repaired; the complete unit must be replaced.
Do not dispose of the device as household waste.
Special handling of individual components may be mandated by law or make ecological sense.
Observe all local and currently applicable laws and regulations.
Application-related technical data are only warranted when used in connection with the Siemens controllers and actuators listed under "Equipment combinations", page 2.
When using the valves with actuators of other manufacture proper functioning must be ensured by the user. Any warranty by Siemens becomes void.
