General Purpose Mini Solenoid Valves
  Dyna-Coil valves are used when you need to convert an electrical signal into a flow of air. 2-way models allow air to flow through the valve when energized. 3-way models allow air to flow through the valve when energized and exhaust when de-energized.

Normally Closed/Normally Open Option
• Normally closed means inlet air is blocked until the valve is energized.
• Normally open means inlet air flows through the valve and is blocked when energized.
