Clippard Instrument Laboratory Inc. has released an introductory CD that highlights the features and specification of the EVP proportional valve line. The EVP Series provides control of air or gas flow. The units also vary the output flow based on the current input to the solenoid. Consistent gain provides a high degree of control for several applications. The valves can be controlled using dc current, open- or closed-loop control, and pulse-width modulation to cover a broad range of applications.
