DXJ3 SERVO-VALVE, DIRECT CONTROLLED

PLEASE ASK FOR PRICE!

The DXJ3 is a ISO 4401-03 four-port servo-proportional valve where the spool moves inside a sleeve. This valve has a direct drive with a linear force motor resulting in high dynamic performances which are independent of system pressure. The spool position is controlled by a linear transducer (LVDT) with closed loop which ensures high precision and repeatability. It is available in four different flow rate control ranges up to 40 l/min, with spools with zero overlap and a mounting surface in compliance with ISO 4401 standards. The valve is featured by integrated electronic based on SMD technology which ensures standard regulations and simplifies the electric wiring. The unit does not require any adjustment other than the possible electronic regulation of the zero. Suitable for control applications with closed loop of position, velocity and pressure. With a loss of power or with a zero-reference signal, the spool goes automatically at rest-position. In this position the valve has a minimum leakage, depending on the operating pressure. A version with external drain is available.
