Servo valve for position, velocity control
-- Control Engineering, 5/1/2003
New Duplomatic DXJ3 Series servo-proportional valve is intended for position, velocity, and pressure control applications. The valve reportedly provides high dynamic performance with a linear force motor, direct-driving a zero overlap spool. DXJ3 operates at pressures up to 5,000 psi, with flows up to 10 gpm in an NFPA standard D03 footprint. Either ±10 V or 4-20 mA control signals work with the valve’s onboard electronics. DXJ3 offers 12 ms maximum response time with <0.2% hysteresis using closed-loop LVDT feedback.
