Pilot-Operated Servovalves for Analog Signals D661 Series
This displacement combined with the special shape of the nozzle directs a focused fluid jet more into one receiver opening mkog the other. Open the catalog to page 9. The other pin is connected to signal common at cabinet side. Open the catalog to page 8.
When making electrical connections to the valve shield, protective groundingappropriate measures Catalog excerpts Moogg Data Performance Specs. Open the catalog to page 7. The spool motion of the main stage is produced by a single-stage pilot valve. During this time more thanvalves have been delivered.
Two-stage proportional valves are mainly used when low threshold and good dynamic response with small signals are required.
Note O-ring counterbore dia.

Open the catalog to page 4. By combining a fast first stage, a suitable spool drive area and integrated electronics, an optimum proportional valve can be offered. Either pin D or E is used according to the required operating direction.
Open the catalog to page 6. A Series Proportional Control Valves are a twostage design.
If no enable signal is available, the spool The input pins D and E are inverting. Meets the requirements of EN This pressure difference results in a pilot flow which in turn causes a spool displacement. Technical Data Performance Specs. Open the catalog to page 3.
The jet now produces a pressure difference in the control ports. The pilot stage drain is through the annular area around the nozzle to tank. A current through the coil displaces the jet pipe from neutral.

The Online Industrial Exhibition. Dd661 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. A Series valves offer the highest flow per For maximum flow, the manifold ports P, T, A and B should have 0. At 0 mA command the spool is in its center position.
