Radiator valves & fittings for water-based heating

Radiator valves and associated fittings form the heart of a well-functioning water-based heating system. The valve regulates the amount of hot water flowing through the element, while the fittings ensure a secure and drip-free connection between the pipe system and the radiator. Replacing worn or sticking valves not only improves indoor comfort, but also reduces the property's energy consumption through more precise control.

Common valve types and their applications

The choice of valve depends primarily on how the pipes connect to the radiator and how much space is available:

  • Straight radiator valves: Used when the connecting pipes come straight from below or straight from the side in line with the radiator's connection port.
  • Angled radiator valves: Best suited when the pipes come out of the wall and are angled towards the radiator connection.
  • Reverse angled valves: An excellent choice in tight spaces where a standard angled valve would place the thermostatic head too close to the wall or window sill.
  • Radiator couplings and sub-parts: Complete pipe sets and distributors used for both 1-pipe and 2-pipe systems, where the supply and return are combined in a single connection.

Important factors to check before purchasing

To ensure that the installation fits and holds tightly, it is important to check some basic technical requirements before ordering:

  • Dimension and thread: The most common dimensions for radiator valves are DN10 (3/8"), DN15 (1/2") and DN20 (3/4"). Always check existing pipes and threads carefully.
  • 1-pipe or 2-pipe radiator system: Distributors and radiator couplings differ depending on the system's structure. In a 1-pipe system, the water passes several elements in series, which requires a distributor with a bypass function.
  • Connection type: Make sure you choose the right type of transition, regardless of whether the system is connected via threaded pipes, copper pipes with compression fittings or PEX hose.
  • Maintenance and packing boxes: If an older valve drips at the spindle, it is often enough to replace the packing box instead of the entire valve body, which saves both time and money.
