RA-C

RA-C is a high capacity two-port valve used in the regulation of hot or chilled water in hydronic systems. The RA-C’s actuator mounting connection is identical to the RA2000 family, allowing a wide selection of thermostatic & electric actuators to suit hydronic applications such as chilled ceilings, chilled beams, fan coils & induction units for heating/ cooling, & radiators.

RA-HC

The RA-HC is a control valve applied together with Danfoss self-acting or Danfoss electronic controls in fan coil units and similar terminal units in any HVAC system. When installed with Danfoss ASV, balancing and control functions are combined representing the complete dynamic hydraulic solution. Combined with Danfoss thermo actuators (TWA) the RA-HC valves provide On/Off control, control the flow over the terminal unit and maintain optimum temperatures based on room load requirements. RA-HC valves have eight presettings, thus the correct quantity of water flow is ensured for each circuit. RA-HC matches high flow capacities and with its compact design only little installation space is required.
