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.

Thermostatic actuator RAVV

 

 

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.
