VL 2 – 2-way valve, flange
VL 3 – 3-way valve, flange
Description
VL 2 |
VL 3 |
VL 2 and VL 3 valves provide a quality, cost effective solution for most water and chilled applications.
The valves are designed to be combined with following actuators:
• |
DN 15-50 with AMV(E) 335, AMV(E) 435 or |
|
|
|
AMV(E) 438 SU actuators. |
|
|
With AMV(E) 25 (SU/SD) or AMV(E) |
|
|
35 actuators (with adapter |
|
|
065Z0311). |
• |
DN 65-80 with AMV(E) 335 or AMV(E) 435 |
|
|
|
actuators. With AMV(E) 56 actuator |
|
|
(with adapter 065Z0312). |
• |
DN 100 |
with AMV(E) 55 or AMV(E) 56, |
|
|
AMV(E) 655, AMV(E) 658 SU/SD or |
|
|
AMV(E) 659 SD actuators. |
Combinations with other actuators could be seen under Accessories.
Features:
•Bubble tight design DN 15-80
•Snap mechanical connection together with AMV(E) 335, AMV(E) 435
•Dedicated 2 and 3-port valve

Valve mounting
Before valve mounting the pipes have to be cleaned and free from abrasion. Valve must be mounted according to flow direction as
indicated on valve body. Mechanical loads of the valve body caused by the pipes are not allowed. Valve should be free of vibrations as well.
Installation of the valve with the actuator is allowed in horizontal position or upwards. Installation downwards is not allowed.
Always install the valve with the arrow on the body in the same direction as the flow. In
order to avoid turbulence, which will affect the measuring accuracy, it is recommended to have a straight length of pipe up and down stream from the valve as shown (D - diameter of pipe).
Note:
Install a strainer upstream of the valve (e.g. Danfoss FVR/ FVF)

Mixing or diverting connection
3-way valve can be used either as mixing or diverting valve (fig.1).
If 3-way valve is installed as mixing valve meaning that A and B ports are inlet ports, and AB port is outlet port it can be installed in mixing (fig.2) or diverting application (fig.3).
3-way valve can be also installed as diverting valve in diverting application (fig.4) meaning that AB port is inlet and A and B ports are outlets.
Note:
Maximal closing pressure for mixing and diverting installation are not the same. Please refer to values stated in Technical data section.
