Miniature valves keep air clean

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.
