7Y-0411 Drain Valve
Cat® Drain Valve Used in Air Filters
Description
The discharge valve is used to expel contaminants and particles from the intake air before they enter the engine. The valve is strategically placed at the air filter outlet to regulate airflow direction and prevent contaminants from flowing back into the intake. When the engine intake cycle begins, the valve opens in response to the negative pressure created during the intake stroke.
Attributes
- Protects the engine from potential damage and reduces the risk of clogging
- Helps maintain optimal air quality
Applications
The discharge valve acts as a one-way flapper valve in the air filter unit; when the engine intake cycle begins, the valve opens in response to the negative pressure created during the intake stroke.
