Temperature controllers VFG, AVTB, MTCV, etc.

AVTB is a direct-acting regulator valve, consists of a control handle, a valve body, a bellows assembly with a capillary tube and a sleeve for the sensor. The valve is used to regulate the water temperature in capacitive and high-speed water heaters of hot water supply systems, oil heaters, etc.

• AVTB. Technical description.

AVTQ is a direct-acting temperature controller with a device for correcting its operation depending on the flow of heated water. Designed for installation on high-speed water heaters, designed for systems with a plate heat exchanger.

• AVTQ (DN 15 mm). Technical description.
• AVTQ (DN 20 mm). Technical description.

FJV is a direct-acting temperature controller designed to limit the temperature of the coolant returned to the district heating system after heat-using devices.

• FJV. Technical description.

MTCV is a direct-acting temperature controller designed to stabilize the temperature and minimize water consumption in the circulation risers of hot water supply systems (DHW).

• MTCV. Technical description.

Combined temperature controllers are a combination of two or more regulators in one unit. For example, it can be a temperature controller with two control units (two-temperature), a temperature controller together with a differential pressure regulator, or a combination of motor control valves with flow or differential pressure regulators.

AVT is an automatic proportional direct-acting temperature controller. In combination with VG, this regulator is designed for use in hot water systems with water heaters. In combination with VGS, the regulator is used for steam or hot water with temperatures up to 200°C.

• AVT/VGS. Technical description.
• AVT/VGU, AVT/VGUF. Technical description.

AFT - thermoelements operating on the principle of liquid expansion. The design of the AFT 06, AFT 26 thermoelements provides for a built-in tuning unit, whereas for AFT 17, AFT 27 it is remote. There are two modifications of sensors with different time constants.

Models: AFT 06, AFT 26, AFT 17, AFT 27.

• AFT 06, AFT 17. Technical description.

RAVK is a direct—acting temperature controller designed for use in hot water supply systems of small buildings (cottages), usually with a capacitive water heater or in heating systems with constant coolant parameters. The regulator can be installed on through-pass (two-way) control valves RAV 8, VMT 8, VMA or three-way valves VMV 15, VMV 20.

The RAVI thermostatic element in combination with the control valves RAV8, VMT8, VMA, VMV is a direct-acting temperature regulator and is intended for use in hot water supply systems of small buildings (cottages), usually with a capacitive water heater.
