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 °C 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.
Main data:
– DN 10-25
– kv 0.25-4.0 m3/h
– PN 10 with RAV-/8, VMT-/8 and KOVM valves
– PN 16 with VMA and VMV valves
– Setting ranges:
– 10 … 30 °C with RAV-/8, VMT-/8, VMA, KOVM valves
– 25 … 45 °C with VMV DN 15 - 20 valves
– 25 … 65 °C with RAV-/8, VMT-/8, VMA, KOVM valves
– 35 … 75 °C with RAV-/8, VMT-/8, VMA, KOVM valves
– Temperature:
– Circ. water / glycolic water up to 30 %:
2 … 90 °C with KOVM valves
2 … 120 °C with RAV-/8, VMT-/8 and VMV valves
2 … 130 °C with VMA valves
– Flow and return mounting
Features and benefits
- Self‑acting temperature control for small hot water cylinders and heat exchangers – no external power needed
- Adjustable setting range 25–65 °C (other ranges available), closes on rising temperature
