Danfoss 013G-8562 Wall Mount Sensor & Dial 6-ft Cap Ra2000

Description:

Danfoss RA 2000 Thermostatic Radiator Valves RA 2000 Thermostatic Radiator Valves 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. Operators and valves are packaged separately to allow an installer to select a suitable combination for each application. RA 2000 valves are fitted with a packing gland assembly that is replaceable while the system is in operation. The packing gland is fitted with a grease cup to ensure the o-ring packing is lubricated for life.  Sturdy EPDM rubber valve disc provides a positive seal against the valve seat at differential pressures of up to 15 PSI in hot water heating systems, while 15psig for low pressure steam systems. Plastic cap supplied to protect the valve pushpin can provide manual control of the valve during installation. If manual operation is required, a separate hand knob is available as an accessory. Valves remain normally open with no operator mounted.  Conforms to ASHRAE / ANSI Standard 102-1983. Brass products such as Danfoss thermostatic radiator valves should not be installed in hydronic or steam heating systems that are being treated with medias that contain, or that during the process of treatment could develop, agents aggressive to brass. In concentrations larger than shown, agents such as Ammonia (0.2mg/l), Mercury (0.01mg/l), Oxygen (0.01mg/l), Carbon Dioxide (0.05mg/l), or Chloride (20mg/l) must be avoided. Further the pH-value of the medium in contact with the brass products should not exceed 9.5. Neglecting the above restrictions may in some circumstances cause damage to the brass in the valve allowing the heating fluid to escape, possibly scalding any bystanders. Note: To avoid internal damage and void the warranty, mineral oils must not come in contact with EPDM valve components.
