Fixed capacity valves
Products shown: 6
RA-FN
The RA-FN valve bodies are used in two-pipe heating systems. The valves are manufactured from brass with nickel plating. The pressure pin of the gland seal is of chromium steel and works in a lifetime lubricated O-ring seal. The complete gland assembly can be replaced without draining down the system. The valves are supplied with a grey protective cap, which can be used for manual regulation during the construction phase. The protective cap must not be used as a manual shut off device. A special manual shut off device (code no. 013G3300) should be used. Compression fittings for 15 mm, 10 mm or 8 mm copper tube are available for RA-FN with 3/8” and 1/2” connections.
RA-G
The high capacity valves, type RA-G, are primarily used in one-pipe systems. All RA-G valves can be combined with all thermostatic sensors in the RA-series. The RA-G valves are fitted with a grey protective cap. This protective cap must not be used as a manual shut off device. A special manual shut off device is available (code no. 013G3300). The pressure pin in the gland seal is of chromium steel and works in a lifetime lubricated O-ring. The complete gland seal assembly can be replaced without draining the system
RA2000
RA2000 thermostats are gas filled with a reaction time of only 10 min - the fastest in the world for mechanical thermostats. The snap-lock makes installation easy and requires no use of tools. RA 2000 thermostats regulate the flow of hot water or low-pressure steam through free-standing radiators, baseboards, or convectors in hot water and two-pipe steam systems.
