Spool hydraulic directional control valve 79-100

pilotelectro-hydraulic

Product description
The Moog Series 79 flow-control servo valves are throttle valves for 3- and preferably 4-way applications. These 3-stage servo valves are designed for applications that require high flow rates and high power. The valves are suitable for electrohydraulic position, velocity, pressure or force control systems with high dynamic requirements.

Features

• 3-stage servo valves for applications requiring high flow rates and high power
• High coil drive forces and robust construction for long service life
• Electrical feedback on the main spool for low hysteresis and excellent linearity
• Optional external pilot supply and return ports
