Flow Patterns

ApplicationThe 6-way characterized control valve is ideal for chilled beams and radiant ceil-ings offering reduced wiring by using a single actuator instead of two. It elimi-nates the need for a change over valve and enables the use of a single coil forheating and cooling.

Dimensions (Inches [mm])

Application NotesThe control valve can be mounted either vertically or horizontally. Do not installthe ball valve with the stem pointing downwards.

When assembled with a 6-Way Valve the MFT actuator must be programmed forproportional control only.

Maintenance6-Way characterized control valves and rotary actuators are maintenance free.Before any kind of service work is carried out, it is essential to isolate theactuator from the power supply (by disconnecting the power).

Wiring Diagrams

2 CAUTION Equipment damage!Actuators may be connected in parallel.Power consumption and input impedance must be observed.

3 Actuators may also be powered by 24 VDC.

4Position feedback cannot be used with Triac sink controller.The actuator internal common reference is not compatible.

6Control signal may be pulsed from either the Hot (source)or the Common (sink) 24 VAC line.

8Contact closures A & B also can be triacs.A& B should both be closed for triac source and open for triac sink.

9For triac sink the common connection from the actuatormust be connected to the hot connection.

The ZG-R01 500 Ω resistor converts the 4 to 20 mA control signal to2 to 10 VDC, up to 2 actuators may be connected in parallel.

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 qualifi ed licensed electricianor 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.
