Low-noise selector valve for medical equipment applications is designed using sliding ceramic components. The valve provides leak-tight operation and features seal surfaces that self-lap to maintain long life. The inlet port can be connected to multiple outlet ports either manually or through computer control. The valve also eliminates the need for multiple solenoid valves, reducing cost and saving space.
