Zirconium material used for zirconium stop valve has excellent characteristics of oxidation-resistant medium and reducing medium corrosion in civil industry, especially reducing hydrochloric acid and sulfuric acid, phosphoric acid and acetic acid with stability above 100 ℃, and has excellent corrosion resistance unmatched by other materials such as titanium alloy, nickel and nickel alloy. Its corrosion resistance is one to several orders of magnitude higher than that of nickel alloy, Zirconium globe valves produced by Shanghai silver shark are widely used in severe corrosion conditions.

Main features:

1. Zirconium stop valve has compact structure, reasonable design, good valve rigidity, smooth channel and small flow anion coefficient.

2. Flexible graphite and tetrafluoro packing are used, which has reliable sealing and light and flexible operation.

3. The driving mode is divided into pneumatic, electric and gear pneumatic transmission.
