Forged Steel Extended Stem High Temperature Full Bore Fully Welded Ball Valve

Specifications:

Simple structure with good tightness and small torque;

With a fully-welded valve body, full bore and the minimum flow resistance (zero actually);

Emergency sealant injection;

Cavity pressure self relief;

Low emission packing;

Fire safe, anti-static and anti-blowout stem design;

Valve seat function DBB, DIB-1, DIB-2;

Optional extended bonnet;

Optional overlay stainless steel on body to seat surface and/or gasket container surface;

Be able to be used for underground installation without corrosion of interior parts, therefore, itis the best application for petroleum and natural gas line systems;

Service life up to 30 years.

Advantages:

The fully welded ball valve adopts forged material, welded body, instead of bolts and nuts, to avoid any potential leakage from body.

The forged body with regular structure and even thickness can avoid shrinkage cavities, pin holes,cracks, sand holes and other defects occurring to casting body valves.

Fully welded ball valves can be spherical and cylindrical type. Usually the spherical type has only one welding seam on the body, the cylindrical type has two welding seam on the body.

Application:

1. City gas: gas output pipeline, the main line and each branch piping and other equipment maintenance.

2. Central heating: large heating equipment output line, main line, branch piping.

3. Heat exchanger : Pipe and each loop opening and closing.

4. Steel plant: a variety of liquid pipelines, optional release gas pipelines, gas and heat piping equipment maintenance, fuel equipment maintenance.
