Spool hydraulic directional control valve D94x

hydraulically-operatedpilot-operatedproportional

Description
The Moog D94x series are hydraulically piloted proportional valves with integrated control electronics, an internal pressure transducer and an optional fieldbus interface. They provide pressure and flow control (p/Q) and can be configured for axis functions (position, velocity, force). Available in two- and three-stage designs and in ISO 4401 mounting sizes 05, 07, 08, 08+ and 10, they suit industrial production lines, test benches and measurement systems.

Overview

• Optimized valve body design for high nominal flow
• Integrated digital electronics with internal pressure sensor for flexible control
• Durable ServoJet pilot valves
• Excellent dynamic response through improved pilot stages
• Multiple fail-safe options for application-specific configuration
