Danfoss Radiator Valves

Plumbing Radiators & Heaters Radiator Valves & Couplings Danfoss Radiator Valves

Discover our wide range of Danfoss radiator valves and accessories that ensure energy-efficient, stable and precise temperature control in water-borne heating systems. Danfoss is a well-known standard in Swedish HVAC and a safe choice for both renovation of existing elements and new installations in villas, apartment buildings and commercial properties.

In this category you will find Danfoss valve housings in straight and angled designs, complete radiator couplings for 1-pipe and 2-pipe systems and necessary connection parts such as compression fittings, nipples and gland boxes. By installing modern radiator valves from Danfoss, you improve the flow balance to the elements, which reduces unwanted temperature fluctuations and helps lower your home's heating costs. Choose the right valve for your radiators at VVSmax and create a comfortable indoor climate all year round.

Buying guide for Danfoss radiator valves

A well-functioning radiator valve is the heart of every water-based heating system. It controls how much hot water is let into the element and determines how effectively a thermostat can regulate the room temperature. Danfoss radiator valves are known for high operational reliability, robust brass construction and long service life in Swedish radiator systems.

Advantages of Danfoss valves

  • Precise flow control: Many Danfoss valves, such as the RA-N and RA-U series, have integrated pre-setting that makes it easy to throttle and balance the water flow across each individual radiator.
  • High operational reliability: Sturdy components and replaceable packing boxes minimize the risk of leakage and make ongoing maintenance easy without the need to replace the entire valve.
  • Standardized connections: Fits common Swedish pipe dimensions and radiator connections, which facilitates both the replacement of old valves and new construction.

Important to consider before purchasing

To ensure that you order the right components, there are a few key factors to check:

  • 1-pipe or 2-pipe radiator system: It is crucial to choose radiator couplings and lower parts that match the property's distribution system. A 1-pipe system requires a coupling with a bypass to avoid interrupting the flow to the next radiators, while a 2-pipe system is connected in parallel.
  • Dimension and pipe routing: Check the dimension of the supply pipe (usually DN10, DN15 or DN20) and whether the pipe connects from the floor or wall. Choose between straight or angled design depending on how the pipes meet the element.
  • Thermostat compatibility: Check the type of thermostat or actuator to be mounted on the valve, as different Danfoss series use specific mounts (e.g. RA mount with snap-in connection or M30 threaded mount).
  • Supplementary fittings: Make sure you have the correct compression fittings, nipples and bushings adapted to the pipe type, regardless of whether the installation is to copper, PEX or steel pipe.
