Would you mind help me on defining the op-amp with this range for Servo valve Control circuit application.

On circuit DC voltage is: 27 Vdc
and the servo operating current on 27 Vdc is 1 Amp.

How about the LM675?

Depending on the valve, a PWM circuit might end up being smaller and cheaper, once you factor in thermal design issues.
