Deskripsi
Pilot-Operated Proportional Valve
The D66x proportional valve features a spool directly mounted in the valve body and is hydraulically pilot-operated. This design enables higher flow rates and supports a variety of fail-safe options. The D66x series utilizes the proven Servo Jet pilot mechanism, characterized by low and stable pilot oil demand. This series is available in two-stage and three-stage configurations, covering sizes 05, 07, 08, and 10. Developed for demanding industrial applications, this proportional valve offers high functional flexibility and dynamic performance.
Performance characteristics:
Valve body design optimized for high rated flow rates
Two- or three-stage valves are available, depending on the required dynamic performance.
Optional servo-jet or nozzle-baffle pilot valves
The improved pilot-stage design results in high dynamic response.
Offers multiple fault protection options to achieve high application adaptability.
Optional features and accessories :
Two-stage or three-stage valves are optional.
Optional servo-jet or nozzle-baffle pilot valves
