The Manley 11317-1 11317 BBM 940 Exhaust Valve is a high-performance automotive component designed for use in racing and high-performance applications. This valve is part of Manley's BBM (Beryllium and Bronze Metal) series, which is known for its exceptional durability and heat resistance.
The 11317-1 11317 BBM 940 Exhaust Valve is a single valve design made from a unique alloy of beryllium and bronze. Beryllium is known for its low weight and high melting point, making it ideal for use in high-heat applications, while the bronze component provides the necessary strength and conductivity. This alloy allows the valve to maintain its structural integrity and functionality even under extreme conditions, ensuring reliable performance.
The 940 designation refers to the valve's stem diameter, which is 9/16inch, making it a common size for high-performance applications. The valve is designed for use with a 1.600inch (40.64mm) intake valve and a 1.575inch (39.98mm) exhaust port. The valve's seat diameter is 1.560inch (39.62mm).
The Manley 11317-1 11317 BBM 940 Exhaust Valve is engineered with a hollow stem design, which reduces the amount of heat transferred to the engine head, allowing for more efficient engine operation. The valve contains a stainless steel spring and retainer for durability and consistent valve action. The valve also features a titanium valve keep and a hardened valve seat to ensure a long lifespan and resistance to wear.
The 11317-1 11317 BBM 940 Exhaust Valve is designed to offer superior performance and reliability for high-performance applications. It is ideal for racing engines and engines that require high-strength exhaust valves that can withstand extreme heat and constant cycling. The valve's unique alloy design and hollow stem construction provide unmatched durability and efficiency, ensuring that it serves as a reliable component for even the most demanding applications.
