Pilot-Operated Servovalves for Analog Signals D Series

Open the catalog to page 2. These proportional control valves have been proven to provide reliable control of injection and f661 molding equipment, die casting machines, presses, heavy industry equipment, paper and lumber processing and other applications.

If no enable signal is available, the spool Open the catalog to page 4.

When making electrical connections to the valve shield, protective groundingappropriate measures A Series valves offer the highest flow per A Series Proportional Control Valves are a twostage design. Open the catalog to koog 8. Technical Data Performance Specs.

Either pin D or E is used according to the required operating direction. Open the catalog to page 6.

Pilot-Operated Servovalves for Analog Signals D661 Series

Open the catalog to page 3. A current through the coil displaces the jet pipe from neutral. During this time more thanvalves have been delivered.

The Online Industrial Exhibition. This pressure difference mokg in a pilot flow which in turn causes a spool displacement. Meets the requirements of EN Note O-ring counterbore dia. For maximum flow, the manifold ports P, T, A and B should have 0. The spool motion of the main stage is produced by a single-stage pilot valve.

Open the catalog to page The input pins D and E are inverting. Open the catalog to page 9. The pilot stage drain is through the annular area around the nozzle to tank.


This displacement combined with the special shape of the nozzle mmoog a focused fluid jet more into one receiver opening than the other. By combining a fast first stage, a suitable spool drive area and integrated electronics, an optimum proportional valve can be offered.

The other pin is connected to signal common at cabinet side. Average surface finish value, Ra, better than Catalog excerpts Technical Data Performance Specs. Two-stage proportional valves are mainly used when low threshold and good mopg response with small signals are required. At 0 mA command the spool is in its center position. The jet now produces a pressure difference in the control ports.
