Our bellows sealed globe valve has a reasonable structure and reliable sealing, with a dual sturdy and durable bellows sealing design (bellows+packing) to ensure zero leakage of the valve stem. No fluid loss, improving factory equipment safety. And comply with international sealing standards. The sealing surface is welded with Co based hard alloy, which is wear-resistant, corrosion-resistant, has good friction resistance, and has a long service life. The valve stem undergoes quenching and surface nitriding treatment, exhibiting excellent corrosion resistance and friction resistance; Valve stem lifting position indication, more intuitive.
● Dual-sealing design (bellows + packing). If the bellows is in good condition, the packing on the valve stem will also prevent leakage and comply with international sealing standards.
● No fluid loss, reduced energy consumption, and enhanced safety of factory equipment;
● Long service life, reducing the frequency of maintenance and lowering operating costs;
● The robust and durable corrugated pipe sealing design ensures zero leakage of the valve stem and provides a maintenance-free condition.
● The valve seat for the gas medium is made of PTFE soft sealing material, which enhances the sealing performance of the valve.
● Resistant to high temperatures. When the temperature is ≤ 425°, the valve seat adopts a conical hard seal, achieving zero leakage in terms of gas tightness.
