Flow/Mounting Details Sequence 1 Sequence 2 Return From Coil To Coil Supply Return To Source To Coil Supply Return To Source Return From Coil 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 efficiency of the system because cross-flow 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.

The control valve can be mounted either vertically or horizontally. Do not install the valve with the stem pointing downwards. A single expansion tank is recommended to ensure same pressure on the heating and cooling loops, this helps to maintain energy efficiency by eliminating migration of water from the cooling to the heating loop. Maintenance: 6-Way characterized control valves and rotary actuators are maintenance-free. Before any kind of service work is carried out, it is essential to isolate the actuator from the power supply (by disconnecting the power).

Actuators may be connected in parallel. Power consumption and input impedance must be observed. Actuators may also be powered by 24 VDC. Only connect common to negative (-) leg of control circuits. A 500 Ω resistor (ZG-R01) converts the 4 to 20 mA control signal to 2 to 10 VDC. Actuators with plenum cable do not have numbers; use color codes instead. Meets cULus requirements without the need of an electrical ground connection. ! WARNING! LIVE ELECTRICAL COMPONENTS! During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
