Products Detail

US standard API bellows sealed globe valve with electric actuator is one of the main products of our factory. We are specialized in the design, manufacture and sales of industrial valves. Bellows sealed globe valve produced by us is sold worldwide. We provide perfect one-stop service for customers.

US standard bellows sealed globe valve has the following characteristics:
1. Dual seal design (bellows + packing) prevents stem packing if bellows fail.
2. Reasonable structure, reliable sealing, excellent performance and beautiful appearance.
3. No fluid loss, reduce energy loss and improve plant equipment safety.
4. Surfacing welding of co-based hard alloy on the sealing surface has the advantages of good abrasion resistance, corrosion resistance, friction resistance, long service life, reduced maintenance times and reduced operating costs.
5. Rugged bellows seal design ensures zero stem leakage and provides no-maintenance conditions.
6. Globe valve stem quality control and surface nitriding treatment, good anti-corrosion and anti-friction performance;
7. The valve stem lifting position indication of the bellows sealed globe valve is more intuitive.
