Original Quality Quadruple Protection Valve 9347050050 For Volvo Trucks
Ensure maximum safety, system integrity, and braking reliability in your Volvo FH, FM, FMX, or FE truck with the genuine OEM quadruple protection valve, engineered as a direct-fit replacement for:
- OEM Part Number: 9347050050
This critical component is part of the dual-circuit pneumatic brake system, designed to isolate individual air circuits in the event of a pressure failure—preventing total brake loss and maintaining control. The quadruple protection valve (QPV) regulates and safeguards four independent air reservoirs (e.g., service brakes, parking brakes, auxiliary systems), making it essential for heavy-duty commercial vehicle safety compliance.
Manufactured to Volvo Group’s exacting OE standards, this valve ensures precise pressure thresholds, leak-free operation, and long-term durability under extreme operating conditions.
