Versa’s C-Series, C3, C5, C7 & C9, valves are multi-purpose four-way, 5 port 2 position or 5 port 3 position, pilot operated pneumatic valves consisting of two body types, sideported and manifold mounted. Pilot supply can be either Inpilot or Expilot for all valves with the exception of the C3 which is only Inpilot. A low power solenoid controls the pilot signal which provides the positive force for shifting the valve spool.
Double solenoid/pilot 5/2 models feature detented offset positions. Double solenoid/pilot 5/3 models feature a spring return to the unactuated center position with all ports blocked or exhaust ports open in the center position or cylinder ports open to inlet.
A balanced, packed spool is the flow controlling element of each valve. The balanced spool allows the force necessary to shift the valve to remain independent of the pressure of the medium being controlled. The use of elastomer sealing provides bubbletight operation thus enabling positive positioning of 3-position devices, and thrift of operation due to no waste of leaking air.
