Stainless steel air valve ideal for raw water mixed with foreign substances, agricultural water, and sewage. High-capacity intake and exhaust type.
The air layer created inside the valve prevents foreign substances from adhering to the shut-off section. You can choose from stainless steel (SCS14A) or nylon resin. Features: - This air valve is designed for use in piping where fluids containing foreign substances flow. - The air layer created by the low-position float and conical valve box blocks debris and foreign substances, preventing shut-off failures and operational issues. - The unique rolling seal structure prevents the valve seat from sticking. - It accommodates both exhaust and intake, preventing the piping from becoming vacuumed. - The water hammer prevention option protects the air valve and piping by reducing exhaust volume while maintaining intake performance.
