This 100 Series is a 120V (8.5W) direct solenoid operated 3-way poppet valve.  It features a short stroke solenoid, a balanced poppet and powerful return spring.  These features translate into high shifting forces, fast consistent response times, and long life.  The unique balanced design means versatility in piping – the valve can be configured as a 3-way or 2-way – normally closed or normally open or can be used for vacuum, diverter or selector applications.
