Moog D680 Series Proportional Valves

Moog has launched an updated version of the D680 Series Proportional Valves — throttle valves for 2-, 3-, 4- and 5-way applications — suitable for electrohydraulic position, velocity, flow and force control in hydraulic systems. The D680 product range has integrated electronics and is suitable for applications with high dynamic response requirements.

The newly launched version in this series is a two-stage valve with a closed loop controlled D633 direct drive servo valve as the pilot stage. This latest version provides increased dynamics and repeatability, and is more robust than the existing version, making it suitable for use in more demanding environments.

The D633 direct drive servo valve pilot stage with open loop control has been available for many years. Moog developed the new version in conjunction with machine builders in the plastics metal forming, presses and steel production sectors, better to meet the needs of these applications.

The Moog D680 Series Proportional Valve series is a design that provides repeatable control for machinery in industries such as injection and blow moulding, die-casting, steel production, metal forming and presses and timber processing. The range can be easily integrated in new designs and configured to meet the exact application and performance requirements of industrial machinery and equipment.
