The valves undergo intense   cleaning, including ultrasonic   cleansing, to remove   hydrocarbons and particulates.   Assembly, inspection,   and testing take place in an   enclosed and controlled clean   room with positive-pressure,   high-efficiency particulate air   (HEPA) filtration. 
 The Oxygen Clean OE Series electronic values also have an unconventional actuation system. Most solenoid valves use a plunger that moves inside a coil, making the actuator heavy and slow due to relatively high inertia. The OE design, instead, uses a spider spring and armature that reduce mass and speed response. And the spider-spring/armature combination reportedly gives exceedingly long life.
 OE Series valves are designed for use with oxygen and low-pressure pneumatic applications. Three models are rated to 105 psi and 0.6 scfm. They are available in two or three-way, normally close of fully ported versions with 6, 12, and 24 Vdc.
 Response time is 5 to 1 msec and power consumption is only 0.67 W.
 OE Series valves use a spider spring and armature to reduce mass, giving faster response and longer life than that of typical solenoid valves.
