Kombinirani termostatski regulatori

Product types shown: 3

AVTB
AVTB je regulator temperature bez pomoćne energije koji služi regulaciji temperature vode u spremnicima tople vode, izmjenjivačima topline, grijačima ulja itd. Regulator se zatvara pri porastu temperature.

Regulator ima regulacijski ventil, termostatski pogon i ručku za podešavanje temperature. Termostatski pogon sastoji se od mijeha, impulsne cijevi i osjetnika.
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.
AVTQ controller consist of a thermostatic actuator, diaphragm element, main valve and pilot valve. Thermostatic actuator with diaphragm element and main valve are installed on the district heating (primary) side. The diaphragm element is, via impulse tubes, connected to the pilot valve on the domestic hot water (secondary) side.
FJV
FJV is self-acting temperature controller used to control:
- return water temperature from hot water tanks in direct connected district heating systems,
- return water temperature in district heating systems with mixing loop.
The FJV ensures that return water is cooled to required temperature before it flows back to the district heating plant. Controller closes on rising temperature.

The controller has a control valve, thermostatic actuator and handle for temperature setting. Thermostatic actuator consist of a bellows only.

For block and district heating systems.
