Features and structure of forged steel welded globe valve:

Compared with the gate valve, the globe valve has a simpler structure, and is more convenient to manufacture and maintain; the sealing surface is not easy to wear, scratch, and has better sealing performance and longer life; when opening and closing, the disc stroke is smaller, and the opening and closing time is shorter .

Application scope:

1、The design and manufacture of globe valve products conform to the requirements of advanced foreign standards such as American standard ASME B16.34 and British BS1873.

2、The shape of the valve body is barrel-shaped or streamlined and beautiful. The circulation shape is straight-through. The fluid resistance is small.

3、The sealing surface of the closing piece (brake) and the valve seat adopts conical sealing, with small closing force, erosion resistance and reliable sealing.

4、The valve seat can be a replaceable valve seat, which can be arbitrarily combined with the material of the closing sealing surface to meet the requirements of working conditions and prolong the service life.

5、Large-caliber, high-pressure stop valve adopts lifting rod according to the requirement of closing force.It is also equipped with rolling bearing type and impact type handwheel to reduce closing force.

6、The materials of the main body, internal parts, fillers, and fasteners can be reasonably combined according to user requirements or actual working conditions.

Straight-through globe valve：

The wellhead channel of the medium is in the same direction and is 180°. This form of shut-off valve makes the flow state less damaged than conventional shut-off valves, so the pressure loss through the valve is correspondingly reduced.

Working principle:

The closing principle of the globe valve is to rely on the pressure of the valve stem to make the sealing surface of the disc and the sealing surface of the valve seat closely fit to prevent the medium from flowing.
