Cast Stainless Steel Swing Check Valves – ANSI Class 150 / 300
The Cast Stainless Steel Swing Check Valves ANSI Class 150 / 300 are designed to prevent reverse flow in industrial pipeline systems. The valve adopts a swing-type disc mechanism, allowing fluid to flow freely in the forward direction while automatically closing when reverse flow occurs.
Manufactured with a precision investment casting body and cover, the valve provides excellent structural strength, corrosion resistance, and long service life under demanding operating conditions.
The valve features a bolted cover design, allowing convenient maintenance and inspection. The integral seat structure ensures reliable sealing performance and minimizes leakage risk during operation.
The face-to-face dimensions comply with ANSI B16.10, ensuring compatibility with international pipeline standards and easy installation in existing piping systems.
These swing check valves can be installed in horizontal or vertical pipelines, making them suitable for various industrial applications.
Supplied by SHAANXI GOLD-STONE I/E CO., LTD., the valves are widely used in oil and gas pipelines, petrochemical plants, power stations, water treatment facilities, and industrial processing systems.
