Application

The 6-way characterized control valve is ideal for chilled beams, radiant ceilings, and Fan Coil Units offering reduced wiring by using a single actuator instead of two. It eliminates the need for a change over valve and enables the use of a single coil for heating and cooling.

Operation

A loop pressure relief is designed into port number two (2). This allows the increased pressure to dissipate to the supply loop on port number one (1). This is intended to release any pressure build up in the loop (coil) when the valve is in the closed position and is isolated from the system expansion vessel. The change in pressure occurs due to a change in the media temperature in the coil while isolated from the pressure vessel. The pressure relief does not affect the effi ciency of the system because cross-fl ow cannot occur between the heating and cooling loops. The system loops (heating/cooling) should share a common expansion vessel to keep the system pressure and volume balanced.
