Danfoss radiator valves with pre-setting are used in two-pipe water based heating systems to ensure optimum distribution of the water in a heating system.
Pre-setting valves are available for normal and low flows and for reversed flow.
The pre-setting facility allows precisely setting of calculated flow. Pre-setting requires no tools. |

Danfoss provides a comprehensive range of radiator valves with fixed capacity.
RA-FN normal flow valves are used in two-pipe heating systems.
Versions: straight and angled with sizes from DN 10 to DN 25 and horizontal angled with sizes from DN 10 to DN 20.
RA-FNE normal flow valves are used in one-pipe heating systems.
Versions: straight, right mounted angle and left mounted angle with the size DN 15.
RA-G (RTD-G) high capacity valves are used in gravity systems or in pumped one-pipe systems.
Versions: straight and angled with sizes from DN 15 to DN 25. |

| Modern radiators are often manufactured with integrated valves (also called built-in valves), which are built into the radiator at the time of manufacture; the radiator thermostat being fitted on site by the installer. |

RA 15/6T and 15/6 TB (normal flow) are special lance valves with flow and return in one radiator connection. Lance valves are suitable for towel dryers, enabling another radiator connection to be used for an electric heater.
RA 15/6T valves are used in one-pipe systems, RA 15/6TB valves are used in two-pipe systems.

| Manifold assemblies (normal flow, with or without pre-setting) are universal pipe connectors and regulating valves for radiators. An assembly comprises: A radiator valve, a manifold valve, connection pipe and compression fittings, which may be ordered as seperate parts or as a set. |

| H - piece with integrated valve at the inlet side and shut-off / drain device at the outlet. The thermostatic valve has an integrated pre-setting facility for quick and accurate system balancing. The VHS is the ideal control valve for radiators with 50 mm distance between inlet and outlet. The 50 mm connection is available at all valve-radiators and is increasingly used at design radiators as well as towel rails. At the 6-port universal radiator there are several connection possibilities, among them a 50 mm connection. |

The valve features a pre-setting facility and is based on the accurate and reliable Danfoss quality.
The main applications for theese series of valves are towel rails of the "ladder" type also on design radiators provided with 50 mm connections. This new series of valves can be used creating an visual appealing installation. |

| The FJVR valve (normal flow) is used exclusively in conjunction with the FJVR return temperature limiter sensor. The FJVR valve is mounted in the outlet of a radiator or floor heating circuit. The valve - and sensor can be fitted in any position as long as the flow direction is observed. |
