Thermostatic sensors
Product types shown: 7
AFT 06, AFT 17
The thermostats operate according to the liquid expansion principle. The set point adjuster is directly fitted to the actuator.
There are two sensor designs with different time constants:
- AFT 06 smooth sensor ~120 sec
- AFT 17 spiral sensor ~20 sec
Temperature control of domestic hot water systems with storage tanks and restriction of the return flow temperature in district heating transfer station are the main fields of application. Combinations: temperature controller, safety temperature monitor type STFW.
Type-tested according to EN 14597 in connection with the following valves:VFG 2, VFG 21, VFGS 2, VFG 33 and VFU 2.
RAVI
RAVI is self-acting thermostatic actuator primarily for use for temperature control of small hot water cylinders - either storage type cylinders or instantaneous hot water heaters.
RAVI can be combined with 2-way valves:
• RAV-/8,
• VMT-/8 and
• VMA
Controller closes on rising temperature.
The temperature controller is type-tested according to EN 14597.
RAVK
RAVK is self-acting thermostatic actuator primarily for use for temperature control of small hot water cylinders (e.g. storage tanks) or heat exchangers in radiator heating systems.RAVK can be combined with:- 2-way valves RAV-/8, VMT-/8, VMA, or- 3-way valves VMV and KOVM Controller closes on rising temperature.RAVK 25-45 oC can be combined with VMV DN 15 and DN 20 valves. This combination is used for temperature control in a mixing loop for hot water service.
