Technical Specifications & Features: Detailed standalone specifications for 9904-516 are not publicly itemized. As a member of the 9904 hydraulic valve line, it shares design principles with the series’ large hydraulic 3-way valves and liquid shut-off valves.

Working Principle: Consistent with 9904-series hydraulic valves, it operates via hydraulic pressure acting against a failsafe spring on a double-piston arrangement, enabling fail-safe diversion of fluid upon loss of hydraulic pressure.

Installation & Notes: Must be installed per Woodward’s hydraulic valve documentation. Ensure proper SAE flange connections and verify hydraulic supply pressure is within rated limits.
