A One-piece, Forged Steel, Metal Seat Valve for Critical Applications

One-piece, forged steel,
metal seated ball valve

For applications that require high pressure, high temperature and high safety, consider a one-piece, forged steel, metal seated ball valve. Until recently, limitations in the forging process restricted the manufacturing of larger valve bodies, but now 1/2" to 4" valves in ASME Classes 900 to 4500 are available.

These valves offer the following advantages: a one-piece forged design; a streamlined flow path eliminating cavitation and pressure drop; seats with no exposure to the flow stream; a body cavity isolated from solids build up and flow and erosion resistance.

Forged valves offer greater strength and increased toughness for maximum reliability and safety. They have become the first choice of fossil and nuclear power stations, the nuclear navy and for all severe and critical applications in the chemical and hydrocarbon processing industries.

One particular brand is the Velan Power Ball,  highly advanced, patented, forged, one-piece metal-seated valve designed for high-pressure and high-temperature applications in the power generation and process industries. More information on the Velan Power Ball can be found here.

Because these valves are used in the most critical applications, consultation with application engineers and utilizing factory authorized installers is recommended.
