Choose the right MMA radiator valves for your heating system

MMA radiator valves have long been the first choice in Swedish homes and properties when it comes to reliable control of water-based heating. By regulating the water flow through the radiator, the valve ensures that each room maintains a comfortable and balanced temperature without unnecessary energy waste. Whether you are building a new building, renovating an older radiator system or need to replace a leaking stuffing box, MMA offers flexible and durable solutions adapted to Nordic conditions.

Advantages of MMA radiator valves and accessories

  • High operational reliability: Manufactured with precision in durable materials that can withstand continuous load and pressure variations in the heating system.
  • Smart modernization: With MMA's smart replacement inserts, you can upgrade older valves without having to replace the entire valve housing or drain the entire heating system when using the intended service tools.
  • Precise flow adjustment: The possibility of precise pre-setting with MMA's adjustment tool provides a perfectly balanced heating system where all elements receive the correct flow.
  • Wide range of spare parts: Access to standardized packing boxes, connection couplings and couplings makes future maintenance simple and cost-effective.

Common areas of application

MMA radiator valves are primarily used in water-borne heating systems in villas, apartment buildings and industrial properties. They are mounted directly at the radiator inlet and usually interact with a manual knob or a thermostat that senses the ambient temperature of the room. In major renovation projects in the Million Program properties or older single-family homes, MMA's replacement inserts and radiator couplings are particularly common to optimize energy performance with minimal intervention in the pipework.

Important to consider before purchasing

  • Thread dimension and pipe connection: Ensure the correct dimension (for example DN10, DN15 or G15/G20) and whether the connection is straight, angled or reverse angle.
  • Valve housing model: When purchasing a replacement insert or packing box, it is crucial to match the existing valve housing's designation and year of manufacture for full compatibility.
  • 1-pipe or 2-pipe system: Check the system's structure before choosing a radiator coupler or distributor, as these are adapted for different flow principles.
  • The right tool for adjustment: To achieve the manufacturer's calculated flow and avoid hissing pipes, the associated pre-setting key is recommended during assembly and commissioning.
