Installation and Wiring<br />
The valves should be installed in the horizontal line. Allow 6" for the<br />
cover removal and 12" for complete actuator removal. These actuators<br />
should never be mounted underneath the valve as condensation<br />
can build up and result in a failure of the actuator. Full instructions are<br />
supplied with the product. The diagram below shows the wiring schematic.<br />
For AF-MFT-US actuators, connect as shown in the 'Master'<br />
schematic. For 2 x AF-MFT-US actuators, one actuator motor should<br />
be connected as a 'Master' and the other as a 'Slave' unit, as shown<br />
in the schematic.<br />

Note: Due to temperature capability limitations, maximum saturated steam inlet pressure is 100 psig. For reduced capacity valves, use the<br />
differential pressures for the next valve size down.<br />
