Differential Drive Servo Valve Based on MSMA
Applied Mechanics and Materials, 2012Aimed at the contradiction between high frequency response and large flow of servo valve, the paper puts forward a 2D servo valve with differential drive based on magnetic controlled shape memory alloy(MSMA). To realize large flow control, the valve-spool is set of flow increasing orifice to match the flow increasing window on the valve-sleeve.

Rate sensing servo amplifier for increasing stability of servo controlled leak valves
Review of Scientific Instruments, 1981A servo amplifier is described which increases the stability of the series 213 and series 216 Granville–Phillips servo controlled leak valve. The amplifier provides increased immunity from 60 Hz noise through filtering, negative feedback via a rate sensing circuit, and adjustable gain.

Pneumatic Servo Valve with Negative Overlaps
2019There are three kinds of axial overlap between pneumatic servo valve spool and valve sleeve, namely positive overlap, zero overlap, and negative overlap. Positive overlap, also known as negative opening state, refers to the width of spool shoulder is larger than the width of valve sleeve groove, geometrically forming a positive overlap, negative ...
