Bellows valve ansi standand bellow seal gate valve

Reliable sealing and outstanding performance are achieved through:  

1. Bellows-sealed gate valves, where the key component is the bellows. The lower end is automatically roll-welded to the valve stem and components,  

while the upper end is automatically roll-welded to the connecting plate, creating a metal barrier between the flowing medium and the atmosphere, ensuring zero leakage of the valve stem.

2. A dual-seal design combining a bellows and packing provides dual insurance, ensuring safer and more reliable sealing at the valve stem and meeting international sealing standards.

3. All bellows are 100% tested for leakage according to ISO 15848 Class A standards at the factory; all bellows assemblies and valves are 100% tested to meet Class A standards, ensuring zero leakage.

4. The valve cover is equipped with a grease fitting, allowing direct lubrication of the valve stem, nut, and sleeve, unlike traditional designs that only lubricate the threads.  

5. Ergonomic design with a wheel, customizable for impact-type models 4 inches and above, offering a longer service life and more convenient operation.  

Why Reliable sealing and excellent function:

1.Bellows-sealed gate valve, its key components are bellows, the lower end and the stem and components are automatically welded and welded, and the upper end is automatically welded and welded to the connecting plate, forming a metal barrier between the flowing medium and the atmosphere to ensure the valve The rod has zero leakage.

2.Bellows and packing double seal design, with double insurance, making the seal at the valve stem safer and more reliable, and in linewith intemational sealing standards 3.All bellows have passed the fugitiveness test according to ISO15848 Class A standard 100% when they leave the factory; all bellows components and valves have passed the standard Class A test 100% to ensure zero leakage.

4.The valve cover has its own grease joint, which can directly lubricate the valve stem, nut and shaft sleeve, instead of just adding lubricating oil to the thread in the traditional way.

5.Ergonomic design wheel, 4 inches and above can be customized percussion type, longer service life, easier and more convenient operation.
