Import Cast Steel Swing Check Valve — Buy in Bulk from Supplier in India

The Cast Steel Swing Check Valve from Leader Valves Limited is designed to prevent backflow in high-pressure fluid systems, conforming to API 6D, BS 1868, and ASME B16.34 standards. It features a swing disc mechanism with a bolted cover and pressure-seal design, rated for Class-150 to Class-2500 pressure levels. The valve body is cast from WCB carbon steel, with available material options including LCB, WC6, WC9, CF8M, and CF3M for corrosion resistance in demanding environments. Sizes range from 40mm to 950mm depending on pressure class, with the 50mm model listed as the base unit.

Typical industry standards for cast steel swing check valves include ASTM A216 WCB for body material and ASME B16.34 for pressure-temperature ratings. The valve's fire-safe design meets ISO 10497 criteria, and the pressure-seal bonnet ensures leak-tight performance under high pressure. Dash pot and bypass arrangements are available as optional features for controlled closure or system pressure relief. Standard finishes are bare or epoxy-coated; internal surfaces are machined to minimize turbulence and ensure smooth flow characteristics.

These valves are commonly used in oil and gas pipelines, steam systems, and chemical processing plants where unidirectional flow is critical. Buyers include engineering contractors, EPC firms, and industrial maintenance departments sourcing for onshore and offshore installations. Trade terms typically include FOB Mumbai or CIF ports, with packaging in wooden crates and standard lead times of 4 to 6 weeks. Minimum order quantities are not stated and must be confirmed directly with the supplier.
