This pressure difference results in a pilot flow which in turn causes a spool displacement. A current through the coil displaces the jet pipe from neutral. By combining a fast first stage, a suitable spool drive area and integrated electronics, an optimum proportional valve can be offered. The Online Industrial Exhibition. The jet now produces a pressure difference in the control ports. Open the catalog to page 2. Note O-ring counterbore dia.


The spool motion of the main stage is produced by a single-stage pilot valve.

Pilot-Operated Servovalves for Analog Signals D Series

If no enable signal is available, the spool Either pin D or E is used according to the required operating direction. Average surface finish value, Ra, better than For maximum flow, the manifold ports D61, T, A and B should have 0. Meets the requirements of EN Open the catalog to page 8.

During this time more thanvalves have been delivered. Two-stage proportional valves are mainly used when low threshold d61 good dynamic response with small signals are required.

A Series Proportional Control Valves are a twostage mlog. At 0 mA command the spool is in its center position. Open the catalog to page 6. These proportional control valves have been proven to provide reliable control of injection and blow molding equipment, die casting machines, presses, heavy industry equipment, paper and lumber processing and other applications.
