EVP Proportional Valves

Clippard EVP Series Proportional Flow Control Valves combine the features of the well-known and trusted original EV Series valves with the additional capability of proportional control. The EVP Series provides air or gas flow control, and varies the output flow based on the current input to the solenoid. The consistent gain of this valve provides a high degree of control for many applications.

Controllability and overall value are the main features of the EVP Proportional Valve Series. The valve may be controlled using DV current, open- or closed-loop control, and even PWM (Pulse Width Modulation) to cover a broad range of applications.
