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...
Interested in contact information of pump manuafcturers who offer piston or gear pumps with pressures to 10,000 psi (700 bar) and flows less than 0.75 gpm.
