Compared to bolted body, the ex-stem fully welded body design can prevent any potential leakage from connection of body and bonnet. And the forged body has the advantages of consistent grain size and even thickness to ensure reliable and safe sealing performance. Equipped with extension stem, it can work underground. The transition pipe can be welded to the ends of valve during production.Feature:Body and bonnet welded integrally designExtension stem Double Block & Bleed DesignOptional under-ground & extended stem designFire-safe Certified API 607Blowout-proof stemAntic-static deviceLow Fugitive Emission PackingCavity pressure self-reliefOptional double piston designISO 5211 Mounting Pad加长杆全焊接三维图Administrator_5.0_asm1.pdf
