Frequently Asked Questions
This Swing Check Valve is designed according to the BS1868 standard. It has a pressure rating of 600LB and features a flange end connection complying with ASME B16.5 standards.
The body of the valve is constructed from WCB (Cast Carbon Steel), and it features a metal-to-metal seat sealing. This combination offers high durability and superior resistance to wear, tear, and extreme temperatures.
The non-slam design is engineered to minimize water hammer. By preventing sudden closure shocks, it protects the pipeline structure, joints, and associated upstream/downstream equipment from pressure surge damage.
The Face-to-Face (FTF) dimensions of this 6-inch Swing Check Valve conform to the ASME B16.10 standard, ensuring standard compatibility and easy interchangeability in existing systems.
This valve is rated for W.O.G (Water, Oil, and Gas) applications. It is widely used in water treatment plants, oil and gas pipelines, chemical processing, power generation, and other demanding industrial sectors.
Each valve undergoes rigorous testing, including dimension tests and hydro testing, in compliance with the API598 test standard to ensure leak-free performance and pressure containment reliability.
