Vollverschweißte gelagerte Kugel Ventil

Fully welded trunnion mounted ball valve This series of valve are widely used in industrial area such as long-distance pipeline, petroleum, natural gas, etc. Forged material is used in valve body to ensure the homogeneity under pressure resistance. Joint of valve body adopts welded connection to ensure that there is no potential leak risk in any working environment. It also extends the life of the valve. The design and manufacture of all-welded ball valve are coincided with the standards of ASME, API6D and EN13924 Design Feature: Fully welded body, forged body and ball Full bore or reduced bore Flanged end or welding end Double block and bleed Seat function: single piston effect; double piston effect Automatic internal relief of body pressure Emergency sealant injection system Fire safe design Anti-static device Anti-blow out stem design Body vent device Stem extension(according to requirements) Sour service: materials for pressure-containing and pressure-controccing parts and bolting shall meet the requirements of NACE Mr0175 Product Range: Size:NPS 248, DN 501200 Pressure rating: class 150-2500, PN6-420 Basic design: API6D, EN13942 Face to face dimension: ASME B16.10 Face to face dimensions: EN558-1(flanged ends), EN12982(welding ends) Connecting dimensions: ASME B16.5(<24 flanged ends), ASME B16.47(>26 flanged ends), ASME B16.25(welding ends) Connecting dimensions: EN 1092-1(flanged ends), EN 12627(welding ends) Body materials: carbon steel, stainless steel, duplex stainless steel Operation: lever, worm gearing, electric actuator, pneumatic actuator, hydraulic actuator, gas over oil actuator.
