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 for safety.
