products & developments Features of metal-seated ball valves and special alloy ball valves

The metal-seated ball valves and special alloy ball valves are suitable for applications in the chemical, petrochemical, marine/offshore, oil/gas, refining, and pulp/paper industries. The ball valves are available in sizes from ½" to 24". Valwell Development, established in 1998, specialises in the design and manufacture of ball valves and blind flange valves, with full product ranges including conventional, metal-seated, multiple-way, high-pressure ball valves. The company will be exhibiting at Valve World Expo in Düsseldorf, Germany, on stand 3H02.

Special alloys provide a number of characteristics, including maintaining high performance of mechanical strength under high operating temperatures, and corrosion resistance in difficult working environments.

As well as soft-seated ball valves, Valwell Development Enterprise Co provides customers with further options, with metal-seated ball valves and special alloy ball valves. The metal-seated ball valves provide excellent sealing between ball and seats by metal-to-metal design. Coating materials include hard chrome and tungsten carbide, with precisemachining to achieve a zero-leakage promise. The valves offer advantages such as tight shut-off, low torque design, fire safe, abrasion and corrosion resistance, and a wide range of operating temperatures up to 500°C. Valwell Development can manufacture the ball valves with special alloys by austenitic, super austenitic, nickel- based alloys, and duplex and super duplex alloy, which can be supplied on request.
