The VERSA C-Series valve is an extremely reliable valve that can hold up in extreme elements. All the C-Series solenoid valves utilize a high-performance solenoid pilot design. This design takes advantage of the available media pressure/force to shift valve assuring positive shifting. A low power solenoid controls the pilot signal which provides the positive force for shifting the valve spool. Solenoid/pilot supply can be either Inpilot or Expilot
