About Cast Steel Swing Check Valve
Cast Steel Swing Check Valve (Bolted Cover)
FlowBiz Brand Swing Check Valves are Automatic Valves that open with the forward flow and close with reverse flow.FlowBiz makes Swing Check Valve mounted with a disc that swings on a hinge. The disc swings off the seat to provide forward flow, and when the flow is stopped, the disc swings back onto the seat to block reverse flow.

Superior One-Way Flow ProtectionThis swing check valve is specifically designed to prevent backflow in industrial piping systems. Its flow-responsive, automatic swing disc allows fluid to pass in one direction while instantly closing if reverse flow occurs, thus safeguarding pumps and system integrity. The preferred installation orientation is horizontal, enhancing performance and reliability.
High Durability with Minimal MaintenanceManufactured from high-strength cast steel with options including WCB, WCC, LCB, LCC, CF8, or CF8M, this valve boasts rugged construction and a bolted cover for ease of inspection. With an anti-corrosive epoxy coating and premium gasket and fastener materials, it resists wear and demands very little ongoing maintenance, providing years of dependable service.
Versatile Applications and Wide CompatibilityAvailable in sizes from DN50 to DN600 and suitable for Class 150, 300, and 600, this swing check valve meets diverse industrial needs. Whether handling water, oil, gas, or steam, it offers flexible connection types-flanged or butt weld ends-and operates in temperatures from -29C to 425C, depending on material selection.
FAQ's of Cast Steel Swing Check Valve:
Q: How does the Cast Steel Swing Check Valve prevent backflow in a pipeline?
A: The valve operates automatically, using a swing disc that opens with forward flow and closes securely when flow reverses. This mechanism allows for one-way flow, ensuring no reverse movement of media and thus preventing potential system damage.
Q: What types of media can this swing check valve handle?
A: This valve is suitable for a variety of industrial media, including water, oil, gas, and steam. The material and sealing options allow it to perform reliably across different fluids and pressures.
Q: Where should this swing check valve be installed for optimal performance?
A: Horizontal installation is recommended, as it ensures optimal closing efficiency and reduces disc wear. The valve can be installed at pump discharge lines or wherever non-return flow protection is critical.
Q: What is the maintenance requirement for this cast steel check valve?
A: Thanks to its rugged construction, anti-corrosive epoxy coating, and high-quality components such as spiral wound SS gaskets and alloy steel bolts, maintenance needs are minimal, with long service intervals between inspections.
Q: When should seat and body tests be conducted, and at what pressures?
A: Seat and body pressure tests are usually performed prior to installation and during scheduled maintenance. The body test is conducted at 1.5 times the rated pressure, while the seat test is performed at 1.1 times the rated pressure, following industry practice.
Q: What connection types are available for this valve?
A: Depending on your system's requirements, the valve is available with flanged ends conforming to ASME B16.5 or butt weld ends, facilitating compatibility with a wide range of piping systems.
Q: What are the benefits of using a swing check valve in industrial systems?
A: Swing check valves offer protection against reverse flow, prolonging pump and pipeline life. Their automatic, flow-responsive mechanism requires no external power or actuator, and their robust design ensures high durability with minimal operational wear.
