VALVE PACKAGES — There are limitations on physical size of pneumatic valves, quantity and type of matching components, and required control interface. See Fig. 43.

Consult factory before ordering any special valve package components that are not covered in this book.

Valve packages are shipped with the units or in unit cartons. Valve packages include belled ends for field soldering to coil connections.

All factory-furnished cooling valve packages are arranged to position as much of the package as possible over an auxiliary
