  • High thermal resistance up to 120 degrees Celsius
  • Sturdy 10 bar pressure rating
  • Reliable regulation with a KVS value of 0.65
  • Standardized 3/8-inch sizing for easy integration

Cons

  • Requires specific 3/8-inch pipe compatibility

Setup, Compatibility & Care

Installation should be performed by a qualified heating engineer to ensure the integrity of the system and prevent water leaks. Ensure the pipework is properly drained before removing the existing valve. When installing, verify that the flow direction matches the arrow indicated on the valve body for optimal performance. Regular maintenance involves checking the valve body for signs of corrosion or leakage during seasonal heating system checks. If the valve becomes stiff over time, verify the integrity of the thermostatic head connection.
