Pilot-Operated Servovalves for Analog Signals D661 Series

A current through the coil displaces the jet pipe from neutral. The spool motion of the main stage is produced by a single-stage pilot valve.

If no enable signal is available, the spool Open the catalog to page ,oog Either pin D or E is used according to the required operating direction. Two-stage proportional valves are mainly used when low threshold and good dynamic response with small signals are required. The other pin is connected to signal common at cabinet side. 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.


Open 6d61 catalog to page 5. This displacement combined with the special shape of the nozzle directs a focused fluid jet mooog into one receiver opening than the other. When making electrical connections to the valve shield, protective groundingappropriate measures Open the catalog to page 8.

This pressure difference results in a pilot flow which in turn causes a spool displacement. Open the catalog to page 6. A Series Proportional Control Valves are a twostage design. During this time more thanvalves have been delivered. The input pins D and E are inverting. Meets the requirements of EN Technical Data Performance Specs.
