Does Closing the Exhaust Valve Damage the Car?

[Carrie]

Closing the exhaust valve can damage the car. Below are relevant details about the exhaust valve: Resistant to Deformation: The float of the exhaust valve is made of low-density PP material, which does not deform even after prolonged immersion in high-temperature water. This ensures smooth movement of the float. Resistant to Rust: The float lever is constructed from hard plastic, and the connections between the lever, float, and support are designed with movable joints. This prevents rust formation during long-term operation, which could otherwise lead to system failure and water leakage. The sealing end of the lever is supported by a spring, allowing it to expand and contract with the lever's movement, ensuring a tight seal when not exhausting.
