Thermostatic actuator RAVV
- for 2-way valves RAV-/8 (PN 10), VMT-/8 (PN 10), VMA (PN 16)
Description
RAVV is self-acting thermostatic actuator primarily for use for temperature control in small hot water cylinders and to control flow temperatures in central heating systems.
RAVV can be combined with 2-way valves RAV-/8, VMT-/8 or VMA 15. Controller closes on rising temperature.
There is a special version with a section of the capillary tube coiled up to function as minimum temperature sensor. This version can be used to control air heating coils.
Main data:
•DN 10-25
•kv 0,4-1,6 m3/h
•PN 10 with RAV-/8 and VMT-/8 valves PN 16 with VMA valves
•Setting ranges:
10 … 38 °C / 27 … 57 °C / 40 … 70 °C
•Temperature:
- Circ. water / glycolic water up to 30 %:
2 … 120 °C with RAV-/8 and VMT-/8 valves 2 … 130 °C with VMA valves
•Connections:
- Internal and external thread
•Flow mounting

Application principles
The actuator RAVV must be installed in the flow pipeline only.
Hot water cylinder |
Air heating coil |
Installation positions |
Temperature controller |
|
The valve body must be installed in the flow |
|
pipeline with the flow in the direction indicated |
|
by the cast-in arrow. |
|
The flow temperature must be min. 15 °C higher |
|
than the set closing temperature. |
Temperature sensor
The sensor must be installed in position from horizontal to vercally down.
The sensor must always be placed in a pocket when the temperature is to be measured directly in a medium.
