Floating Ball Valve Manufacturer In USA

Floating Ball Valve Manufacturer in USA SVR Global is a floating ball valve manufacturer in USA supplying quarter-turn isolation valves for oil and gas, chemical, petrochemical, water, utility, marine and industrial process applications. In a floating ball valve, the ball is supported by the seats and is not fixed by a lower trunnion. Line pressure moves the ball slightly towards the downstream seat, creating pressure-assisted sealing. Floating ball valves provide compact construction, tight shutoff, rapid operation and simple maintenance. Floating ball valve types SVR Global manufactures one-piece, two-piece, three-piece, side-entry, top-entry, cast, forged, full-bore, reduced-bore, multiport and jacketed floating ball valves. Size range Compact threaded valves: ¼ inch to 2 inches Three-piece valves: ½ inch to 4 inches Flanged floating ball valves: ½ inch to 12 inches Larger sizes: Available where pressure and operating torque permit Pressure classes ASME Class 150, Class 300, Class 600, Class 800, Class 900, Class 1500, Class 2500, PN10, PN16, PN25, PN40, PN63, PN100, PN160, PN250, PN420, 600 WOG, 1000 WOG, 1500 WOG, 2000 WOG and 3000 WOG.

End connections Raised face flanged, ring type joint flanged, butt weld, socket weld, threaded NPT, threaded BSP, sanitary clamp, union and extended weld ends. Full bore and reduced bore Full-bore valves provide lower pressure drop and higher flow capacity. Reduced-bore valves provide lower weight and more compact dimensions but create additional pressure loss. The actual bore diameter should be confirmed from the approved valve drawing. Operation Lever, lockable handle, worm gearbox, electric actuator, pneumatic actuator and hydraulic actuator options are available. Actuator sizing must be based on breakaway torque at maximum differential pressure and the actual seat material. Standards API 608, API 6D, ISO 17292, BS 5351, ASME B16.34, ASME B16.5, ASME B16.10, ASME B16.25, API 598, API 607, API 6FA and ISO 5211 can be specified according to the valve design. Testing Floating ball valves can be tested for hydrostatic shell pressure, high-pressure seat leakage, low-pressure pneumatic seat leakage, fire-safe performance, fugitive emissions, cryogenic operation and material identification. SVR Global manufactures floating ball valves with cast or forged bodies, soft or metal seats, full or reduced bore and manual or automated operation.
