Single-stage, direct-acting proportional solenoid valves feature flow rates linearly proportional to input current. Flows reach 0.20 Cv over range of 25 to 70 psi with normal air flow rates of 4.2 scfm at 25 psig inlet. Typical power consumption is 5 W. Suspended armature mated with hard seats eliminates friction for high repeatability and low hysteresis. They are available in 5, 12, or 24 Vdc versions for manifold mounting.
