Is it possible to use a VEA series power amplifier for electro-pneumatic proportional valves with a PVQ series compact proportional solenoid valve?

VEA series power amplifies cannot be used with PVQ series valves.
The power amplifier has an AC component (dither signal) in the constant current output.
As PVQ series valves are smaller than those from other series (VEP, VEF, VER, DXT334, etc.), the pressure cannot be set following dither.
Although not handled by SMC, order a constant current source for PVQ control separately.
