Thermostatic actuator RAVV - Danfoss Heating

Data sheetThermostatic actuator RAVV- for 2-way valves RAV-/8 (PN 10), VMT-/8 (PN 10), VMA (PN 16)DescriptionRAVV can be combined with 2-way valves RAV-/8, VMT-/8 or VMA 15. Controller closes on risingtemperature.There is a special version with a section of thecapillary tube coiled up to function as minimumtemperature sensor. This version can be used tocontrol air heating coils.RAVV is self-acting thermostatic actuatorprimarily for use for temperature control insmall hot water cylinders and to control flowtemperatures in central heating systems.Main data:• DN 10 - 25• k v 0.4 - 1.6 m 3 /h• PN 10 with RAV-/8 and VMT-/8 valvesPN 16 with VMA valves• Setting ranges:10 … 38 °C / 27 … 57 °C / 40 … 70 °C• Temperature:- Circ. water / glycolic water up to 30%:2 … 120 °C with RAV-/8 and VMT-/8 valves2 … 130 °C with VMA valves• Connections:- Internal and external thread• Flow mountingOrderingExample:Temperature controller, DN 15,k v 1.6, PN 16, setting range 27 … 57 °C,t max 130 °C, 2-way valve with ext.thread- 1x RAVV thermostatic actuator,27 - 57 °CCode No: 013U1252- 1x VMA DN 15 valveCode No: 065F2034Option:- 1x Imm. pocket, brassCode No: 017-4370- 1x Weld-on tailpiecesCode No: 003H6908RAVV thermostatic actuatorPictureSetting range Capillary tube lenght Max. sensor temperatureCode No.(°C) (m) (°C)1)10 … 38 1 - 5013U125510 … 38 5.0 2) 013U125312027 … 57 1 - 5 013U12521) Incl.
