Description

Leader Cast Steel Swing Check Valves are designed to automatically prevent reverse flow in pipelines, protecting pumps, compressors, and other equipment from damage caused by backflow. The swing-type disc opens with forward flow and closes automatically when the flow reverses, ensuring reliable non-return operation. These valves are widely used in oil & gas, refineries, power plants, petrochemical industries, and process pipelines. Design & Construction: Body Material: ASTM A216 Gr. WCB (Carbon Steel) Disc Material: WCB with 13% Cr Stainless Steel Trim / SS304 / SS316 Seat: Renewable Hard-Faced Seat Ring Cover Type: Bolted Cover (Pressure Seal Cover available for higher pressure classes) Hinge Pin: Stainless Steel End Connections: Flanged (ASME B16.5) / Butt Weld (ASME B16.25) Design: Swing Disc, Self-Actuating Standards & Specifications: Design Standard: API 6D / BS 1868 / ASME B16.34 Face-to-Face: ASME B16.10 Flange Standard: ASME B16.5 Testing & Inspection: API 598 Pressure Rating: Class 150 / 300 / 600 / 900 / 1500 / 2500 Available Sizes: 40 mm (1½“) to 900 mm (36“) depending on pressure class and model. Features: Automatic non-return operation Low pressure drop with full flow passage Tight metal-to-metal sealing Heavy-duty cast steel construction Renewable seat for extended service life Suitable for high-pressure and high-temperature applications Low maintenance and long operational life Applications: Oil & Gas Pipelines Petrochemical & Refinery Plants Power Generation Plants Steam & Condensate Systems Water & Process Pipelines Chemical & Fertilizer Industries Industrial Utility Services Advantages: Protects pumps and compressors from reverse flow Rugged construction for severe industrial service Excellent sealing performance Reliable automatic operation without external actuation Available in manual inspection and IBR-compliant versions (where applicable).
