For maximum flow, the manifold ports P, T, A and B should have 0. Open the catalog to page 9. At 0 mA command the spool is in its center position.
Open the catalog to page 5. By combining a fast first stage, a suitable spool drive area and integrated electronics, an optimum proportional valve can be offered.

Open the catalog to page 4. This pressure difference results in a pilot flow which in turn causes a spool displacement. The jet now produces a pressure difference in the control ports.
The input pins D and E are inverting. Two-stage proportional valves are mainly used when low threshold and good dynamic response with small signals are required. A current through the coil displaces the jet pipe from neutral.
Pilot-Operated Servovalves for Analog Signals D661 Series
When making electrical connections to the valve shield, protective groundingappropriate measures Catalog excerpts Technical Data Performance Specs. Average surface finish value, Ra, better than Mkog 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 moot.
Open the catalog to page 7. If no enable signal is available, the spool Open the catalog to page The Online Industrial Exhibition. The spool motion of the main stage is produced by a single-stage pilot valve.
Note O-ring counterbore dia. A Series Proportional Control Valves are a twostage design. During this time more thanvalves have been delivered.
Meets the requirements of EN A Series valves offer the highest flow per The pilot stage drain is through the annular area around the nozzle to tank. Technical Data Performance Specs. Open the catalog to page 2.

Either pin D or E is used according to the required operating direction. Open the catalog to page 3.
mooy Open the catalog to page 8. This displacement combined with the special shape of the nozzle directs a focused fluid jet more into one receiver opening than the other. Open the catalog to page 6.
The other pin is connected to signal common at cabinet side.
