RAVK is a self-acting thermostatic operator used to control temperatures in small hot-water cylinders (i.e. storage tanks) or heat exchangers in hydronic hot water systems. RAVK closes on rising sensor temperature.
Closes on rising sensor temperature
Three temperature ranges
Mounts on either supply or return side of system
Sensor element can be fitted in any orientation
Dial can be set to limit or lock the setting range
Type: Thermostatic
Required Valve Body: VMT or KOVM
Capillary Length: 6 ft. 6 in. (2 m)
KOVM mixing valve bodies are designed to maintain room temperature by controlling hot (or chilled) water flow through radiators, fans, convectors, etc. Due to the KOVM’s unique bypass design, a constant system flow is achieved regardless of the room’s heating (or cooling) requirements. Therefore system pressures and flow rates are automatically kept constant without the need for pressure controlled bypass valves.
The VMT valve is a 2-way seated valve, used primarily for heating systems. The valve can be combined with the following thermostatic elements from Danfoss: RAVK, ABV, TWA-V or RA2000 wall mount operators.
AVTB direct acting and AVTB-RA reverse acting proportional controllers are used to regulate the temperature of water.
