Servo or Servo- Proportional Valves

[rgedney]

I am interested in a servo or servo-proportional 4-way valve.

Specifications:

Operating Pressure: 1,000 - 2,000 psi, Hydraulic Fluid
Flow: 1 - 2 gpm
Electronic Interface: Does not Matter (ie. +/- 10V input or ma coil)
Frequency Response: > 20 HZ

Application: Closed loop position control.

Who manufactures an inexpensive valve for this application?
