Termostatis Sensors and Valves

AVT / VG (F)

STM/VG(F) and STM/AVT/VG(F) are self-acting proportional temperature controllers used for temperature control and temperature monitoring of drinking water, water and water glycol mixtures for heating and district heating systems. VG - valve with external thread VGF - valve with flange Controller closes on rising temperature.

AVT / VGS

The AVT/VGS controller is a self-acting proportional temperature controller developed primarily for steam or hot water applications for temperatures up to 200 °C. Controller closes on rising temperature. The controller has a control valve VGS, thermostatic actuator and handle for temperature setting. Thermostatic actuator consist of bellows, capillary tube and sensor.

AVT / VGU-F

The AVT / VGU(F) is a self-acting proportional temperature controller developed primarily for cooling applications. Controller opens on rising temperature. The controller has a control valve VGU(F), thermostatic actuator and handle for temperature setting. Thermostatic actuator consist of bellows, capillary tube and sensor. The temperature controller is type-tested according to EN 14597

QTL /AB-QM set

QTL is self-acting thermostatic actuator primarily for use for temperature control of small hot water cylinders.

RAVI, RAV-8 (PN10), VMT-8/(PN10), VMA (PN16)

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.

RAVK / RAV / VMT /VMA / KOVM / VMV

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. Ordering Example: Temperature controller, DN 15, kv 1,6; PN 16; setting range 25 … 65 °C; Tmax 130 °C; 2-way valve with ext. thread; - 1× RAVK thermostatic actuator, 25 … 65 °C Code No: 013U8063 - 1× VMA DN 15 valve Code No: 065F2034 Option: - 1× Imm. pocket, brass Code No: 065-4414 - 1× Weld-on tailpieces Code No: 003H6908 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.

RAVV/ VMT

The RAVV is a non-electric operator that thermostatically controls the flow of water through the VMT 2-way valve. The self regulation of temperature control through the RAVV and VMT assembly is primarily used for storage tanks, radiant heating or heat exchanger applications.

STM / VG(F) /AVT

STM/VG(F) and STM/AVT/VG(F) are self-acting proportional temperature controllers used for temperature control and temperature monitoring of drinking water, water and water glycol mixtures for heating and district heating systems. VG - valve with external thread VGF - valve with flange Controller closes on rising temperature.

STM / VGS / AVT

STM/VGS and STM/AVT/VGS are self-acting proportional temperature controllers used for temperature control and temperature monitoring primarily in steam or hot water applications for temperatures up to 200 °C. VGS - valve with external thread Controller closes on rising temperature.

STW/VFG(S) 2, STW/AFT/VFG(S) 2

The controllers STFW/VFG(S) 2 and STFW/AFT/VFG 2 are used for temperature control and temperature monitoring of drinking water and heating systems. • Type-tested acc. to EN 14597-2015 • District heating systems acc. to DIN 4747 • Heating systems acc. to DIN 4751 and DIN 4752 • Water heating systems for drinking and industrial waters acc. to DIN 4753
