Product Details

Underground Fully welded ball valves are especially designed for gas transportation and storage industries. 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 design

Extension stem 

Double Block & Bleed Design

Optional under-ground & extended stem design

Fire-safe Certified API 607

Blowout-proof stem

Antic-static device

Low Fugitive Emission Packing

Cavity pressure self-relief

Optional double piston design

ISO 5211 Mounting Pad
