Model 501A is a multi-purpose valve offering high flow rates (to 275 scfm at 125 psig). With all ports on the same vertical plane, the 501A offers straight-line plumbing. It is constructed of lightweight aluminum which has been hardcoated for greater resistance to wear. With the pilot pressure connected to pilot port, four functions are possible.
- Normally Closed: supply to NC port. NO port becomes exhaust port. CYL port to work.
- Normally Open: supply to NO port. NC port becomes exhaust port. CYL to work.
- Directional: supply to CYL port. Pilot air shifts NC open and NO closed.
- Di-Media: supply #1 to NO; supply #2 to NC. CYL port is common.
