Air valve space for sewage, raw water, agricultural water, and rainwater, D25 type.

An air valve made of nylon resin, ideal for raw water, agricultural water, and sewage systems mixed with foreign substances.

The air layer created inside the valve prevents foreign substances from adhering to the shut-off section. You can choose between stainless steel (SCS14A) and nylon resin. *The stainless steel body part is coated with polyester on both the inside and outside. The flange part is uncoated. 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 water shut-off failure 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.
