Main advantages of the product:
1.Bellows sealed gate valve, the key component of which is metal bellows, adopts automatic roll welding at its lower end and valve stem assembly, and automatic roll welding at its upper end and connecting plate, forming a metal barrier between fluid medium and atmosphere to ensure zero leakage of valve stem.
2.The valve has double sealing design (both bellows and packing). If bellows fails, valve stem packing will also avoid leakage and conform to international sealing standards.
3.The bonnet is provided with a greasing joint, which can directly lubricate the valve stem, nut and shaft sleeve, unlike the traditional method of only adding oil to threads.
4.Ergonomically designed handwheel has longer service life, easy and convenient operation, and is safer and more reliable.

DIN Sleeved Plug Valve Maker in China: DIN Sleeved Plug Valve, API 599, API 6D, PN16-PN160, DIN 3202 F1, DIN 2543-2549, DIN 3230.

The use of the German standard card sleeve plug valve.
1. Reasonable product structure, reliable sealing, excellent performance and beautiful appearance.
2. Its sealing is achieved by sealing the cover around the cover. Unique 360°metal lip protection fixed card sets.
3. The valve has no cavity to accumulate in the medium.
4. The metal lip provides a self-cleaning function when spinning, which is suitable for viscous and easily fouling conditions.
5. Two-way flow, easy to install.
6. The material and flange dimensions of the parts can be selected according to the actual working conditions or users' requirements, and meet all kinds of engineering needs.
