The SCAR Stainless Steel Composite Exhaust Valve is a specialized exhaust device designed for sewage pipeline projects. Its core design, achieved through a stainless steel float ball and plug, enables automatic exhaust functionality. It is suitable for pipeline high points or dead-air zones, effectively removing gases from within the pipeline to ensure normal pipeline operation.

Working Principle

As the pipeline starts filling with water, the valve disc remains open to vent a large amount of air; once the air is exhausted, the float rises and closes the valve disc. During normal operation, a small amount of air accumulates inside the valve. As the water level drops, the float descends, and the air is expelled through a small hole. When a vacuum occurs in the pipeline, the plug head automatically opens to intake air, preventing the pipeline from bursting.

Structural Features

Balling Design: Stainless steel ball at the bottom of the valve body to prevent debris from clogging the exhaust port, ensuring sealing performance.

‌Material: The valve body is made of stainless steel, offering excellent corrosion resistance and a long service life.‌

‌Applicable Temperature Range: -29℃ to +80℃ operating temperature.‌

Performance Parameters

Nominal Pressure: 1.6 MPa (some models up to 1.0 MPa).

‌Connection Type: Flanged.‌

‌Applicable Media: Water supply and drainage, fresh water, etc.‌

Installation and Maintenance

Ensure the pipeline pressure is not less than 0.02 MPa; otherwise, leakage may occur.
