Technical Specifications & Features: Standalone specifications for 9908-354 are not publicly itemized. It shares the design lineage of Woodward’s liquid fuel shut-off valves, featuring fail-safe spring return and rapid bypass upon signal loss.

Working Principle: Operates via hydraulic pressure acting on a double-piston arrangement with a failsafe spring. Upon loss of hydraulic trip pressure, the return spring forces the piston to the full bypass position.

Materials & Construction: Consistent with the 9904/9907 liquid valve family: hardened stainless steel internal metering components, dual seal design with vent port, static elastomeric external seals.

Installation & Notes: Installation must comply with Woodward’s liquid fuel valve manuals. Proper fuel filtration and SAE flange standards (SAE J518 Code 61) apply.
