External Air Supply (E):For solenoid actuation below the stated minimum pilot pressure or for vacuum applications, a 10-32 tapped external air supply allows the solenoid to be operated at different pressures than the power section.
Add "E" to the end of the model number.
Single Valves: State model number and voltage, if applicable.
Stacking Options: If your application calls for the use of several valves, it is often advantageous to stack them. Because all valves within a stack are supplied air from a common source and are vented through common exhaust ports, plumbing time and fitting costs are greatly reduced. Stacking also assures that your control valves are located centrally for more convenient trouble shooting and maintenance. Each stack valve body is attached only to its immediate neighbors so that valve additions, replacements, or deletions are easily achieved.
Add an “M” to the single valve model number and state voltage if applicable - specify number and type of valves in each stack.
Note: Explosion Proof coils may not be stacked next to each other because of their greater size.
Isolator Discs: Specify isolator discs only if you will need to isolate valves within a stack.
