Air valves made of nylon resin, ideal for raw water, agricultural water, and sewage systems mixed with foreign substances.
It prevents the adhesion of foreign substances to the shut-off section by creating an air layer within the valve. You can choose from stainless steel (SCS14A) or nylon resin. Features: - A rapid air valve designed for use in medium to large diameter 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 body 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.
