Servo-hydraulic fatigue test machines25kN - 50kN - 100kN
Dynamically rated for 210 bar supply allowing a Dp = 70 bar across the servo valve (static = dynamic x 1.5).
Built-in excluder seals and dribble lines.
Standard servo valve for testing frequencies up to 70 Hz.
High response servo valve for testing frequencies up to 100 Hz
(providing an adequate oil supply is ensured).
