The model 95 Series, SPRIT, is a mini 2-way motorized ball valve designed as an economical alternative to solenoid valves for use in high-fouling environments.  It is considered "mini" because it only measures approximately 3 inches wide by 3 inches tall.  The Sprite is motor driven open by in line voltage and motor-driven closed by way of a built in capacitor.  This has the benefit of ensuring that the valve will close even on a complete loss of power and it only requires two wires to power it. The long service life valve and actuator (approximately) 70,000 to 100,000 cycles) includes a manual override and a visual indicator of valve position.
