Spool hydraulic directional control valve 730

pilotelectro-hydraulic

Product overview
The Moog Series 730 servo valve is a two-stage flow-control valve with mechanical feedback (MFB) designed for electrohydraulic position, velocity, pressure or force control systems that require high dynamic response, stability and precision. The simple nozzle‑flapper pilot stage provides high resolution and low hysteresis, supporting accurate closed‑loop control in industrial applications.

Features

• 2-stage flow control with mechanical feedback (MFB)
• Nozzle‑flapper pilot stage for high dynamics, high resolution and low hysteresis
• High coil forces and rugged main stage construction for extended service life
• High‑pressure version available for continuous operation up to 8,000 psig
• Intrinsically safe version available for certified use in hazardous areas
• Optional X‑Port (external pilot supply) and Y‑Port (return) connections
