Hydraulic PWM valve controllers

[truview]

Hello,

Has anyone heard of hydraulic PWM proportional valves that operate above 1000Hz? I need to spec a controller for as yet unknown valves (it's a test bench) and could save some $ if I limit the controller to 1000Hz.

[Not sure if this is the right forum. Please re-direct me if not]

Thanks,
-Dave

Maybe useful for supplier sources.
