Cast Steel Check Valve – Reliable Backflow Prevention

Cast Steel Check Valve
The cast steel check valve is a dependable and durable valve designed to prevent reverse flow in piping systems. Built from high-quality cast steel, it offers exceptional strength and resistance to harsh operating conditions. Among its types, swing check valves are widely used for their simple design and reliable performance, allowing fluid to flow in one direction while automatically closing to stop backflow. Cast steel check valves are suitable for a variety of industrial applications, providing long service life and consistent functionality in systems handling different pressures and temperatures.

The Mecco cast steel check valves are designed and manufactured according to API 6D, API 594, BS 1868, GB/T 12235, and GB/T 12236 standards. Pressure ratings include CL150, CL300, CL600, CL900, CL1500, and CL2500 (or PN16–PN420). If additional pressure levels are required, the design can be based on ASME B16.34 or GB/T 12224. The temperature range is -29°C to 538°C.
Size:
NPS 2~~NPS 60 (DN50~~DN1500); sizes beyond this range can be custom manufactured upon request.
Material:
Body materials are selected according to customer orders. Common cast materials include WCB, LCB, WC6, WC9, WC5, C12, C12A, CF8, CF8M, CF3, CF3M, CF10, CF10M, CF8C, CK20, CK3MCuN, A4, 5A, 6A, CN7M, CN3MN, M30C, CU5MCuC, CW6MC, CW12MW, CY40. Other uncommon materials can be customized upon request.
Trim/Pin:
Trim and pin materials are configured according to API 6D, API 594, BS 1868, GB/T 12235, GB/T 12236 standards or customer requirements.
Construction:
Swing type (including tilting disc), lift type, axial flow type, double-plate type; with bolted bonnet or pressure-seal bonnet, or customized designs according to customer requirements.

Forged Large-Diameter GGC Valves

Forged Large-Diameter GGC Valves

In some special service conditions where high quality is essential and customers cannot accept the potential risks associated with casting—such as in high-pressure hydrogenation, oxygen service, or toxic media—customers may choose forged materials even for large-diameter, moderate-pressure applications where casting is typically used. These products follow the same applicable standards and scope as the cast gate valves, globe valves, and check valves mentioned previously.
