Bellows valve

Product Overview

The bellows valve is made of new non-metallic materials, which can withstand long-term high temperature and high pressure without losing elasticity. Moreover, the contact area between the plunger and the sealing ring is large, and the sealing ring is made of mixed material with good performance, reliable sealing and durability. It is mainly used in metallurgy, electric power, chemical industry, oil refining, chemical fertilizer, light industry, food and other industries.

Structural characteristics

1. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
2. The sealing surface is overlaid with Co based cemented carbide, which has good wear resistance, corrosion resistance, scratch resistance and long service life.
3. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance and scratch resistance.
4. The valve is equipped with reverse sealing structure, which is reliable.
5. Parts material and flange size can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
