Dual Bypass Valve Repair & Overhaul
FAA & EASA certified dual bypass valve repair and overhaul.
About the Dual Bypass Valve
A dual bypass valve is a pneumatic control valve in the air-management system that regulates two parallel flow paths or selectively diverts air around a component such as a heat exchanger or pack section to manage temperature and flow. Typically incorporating dual butterfly or poppet elements with a shared actuator and control reference, it modulates how much air bypasses versus passes through, balancing conditioning performance against thermal and pressure constraints. Its primary function is coordinated flow distribution and temperature trimming. In service it experiences butterfly-shaft and bushing wear, actuator and linkage backlash, seal and seat degradation, spring fatigue, and contamination or coking from hot bleed air, leading to leakage, sluggish or inaccurate modulation, and position error. Overhaul restores shafts, bushings, seals, and actuation, then verifies calibrated travel, leakage, and response.
