Cast Steel Bellow Seal Globe Valve adopts a sealed structure. In common valves, the packing seal of the valve stem ages quickly and is prone to leakage, but this design completely eliminates these disadvantages. In addition to enhancing the efficiency of materials and the safety of production equipment, it not only reduces maintenance costs and frequent product maintenance, but also provides a clean and safe working environment. The double-seal design (bellows and packing) of Cast Steel Bellow Seal Globe Valve will prevent external leakage if the bellows fails. There is no liquid loss, but energy loss is reduced and equipment safety is enhanced. Longer service life, less maintenance and lower operating costs. The robust and durable bellows seal design ensures zero leakage of the valve stem, providing more reliable performance and requiring no maintenance. Quenched rods and surface nitriding have excellent corrosion resistance and wear resistance. It features excellent performance, elegant appearance and clearer indication of the valve stem position.

Performance

• This product has logical structure, reliable seal, excellent performance and nice design.

• The seal surface is build-up welding with Co hard alloy, which is attrition-resistant, corrosion-resistant, has good friction resistant and long life.

• The stem is quenched and tempered, and its surface is treated by nitriding treatment, thus it has good corrosion resistant and friction resistant.

• It has double seal capability, thus is more reliable.

• The stem may show the position of lift, thus it is clearer.

• The part material, flange and butt weld end dimension may be selected according to current operating condition. and users' requirement, so that meet the requirements of various engineering.
