AVTB
AVTB is self-acting temperature controller used to control the water temperature in hot water tanks, heat exchangers, oil preheaters, etc. Controller closes on rising temperature.
The controller has a control valve, thermostatic actuator and handle for temperature setting. Thermostatic actuator consist of a bellows, capillary tube and sensor.
AVTQ
AVTQ is a self-acting flow-compensated temperature controller primarily for use in district heating systems with plate heat exchangers for instantaneous hot water production. It closes on rising sensor temperature.
It has permanent no-load (idle) temperature setting on about 40 °C (DN15) and 35 °C (DN20) which is offset by a pilot valve using flow-compensation principle during tapping. Tapping temperature can be set individually.
AVTQ prevents high temperatures in the heat exchanger when no hot water is tapped by rapidly shutting off the heat supply (e.g. hot district heating water). AVTQ can be used with most plate heat exchangers. However, the heat exchanger manufacturer should be contacted to ensure that the chosen heat exchanger has been approved for use with the AVTQ.- Pressure-controlled opening/closing on start/stop tapping.
- Infinite adjustment of operating temperature.
- Pressure-controlled opening/closing on start/stop tapping.
FJV
Le FJV est un régulateur de température automoteur utilisé pour limiter :
- la température maximale des réchauffages de ballon sanitaire ;
- la température de retour dans les systèmes de chauffage centralisés avec boucle de mélange.
Le régulateur est doté d’une vanne de régulation, d’un actionneur thermostatique et d’une poignée pour régler la température. L’actionneur thermostatique est composé uniquement d’un soufflet.
Pour systèmes de chauffage centralisés et en bloc.- la température maximale des réchauffages de ballon sanitaire ;
