Zirconium Valve Manufacturer in India

Zirconium valves may be selected for highly corrosive chemical duties where the passive oxide film remains stable under the defined process conditions. Performance can change significantly with temperature, concentration, impurities and oxidizing species, so the material should not be presented as universally corrosion-proof. Speciality Valve manufactures Zirconium valves for compatible chemical applications requiring these material characteristics. Material and valve selection should consider the complete process chemistry, temperature, pressure and the compatibility of all wetted components.

Corrosion Resistance:

Zirconium performance depends strongly on concentration, temperature, impurities and oxidizing species. Zr 702 is generally selected where corrosion resistance is the primary requirement, while niobium-alloyed Zr 705 provides higher mechanical strength. Neither grade should be treated as universally resistant across all acid, alkaline or chloride environments.

Zirconium Valve Types:

• Zirconium Floating Ball Valve: Quarter-turn isolation using a floating ball design.

• Zirconium Gate Valve: Straight-through isolation with low flow restriction when fully open.

• Zirconium Globe Valve: Used for throttling and controlled flow regulation.

Zirconium Valve Specifications:

Zirconium Valve Applications:

• Corrosive Chemical Transfer: Isolation or flow-control duties where Zirconium is verified against the complete chemical composition.

• Acid Process Systems: Selected mineral-acid service where Zr 702 or Zr 705 is compatible with concentration, temperature and contaminants.

• Chemical Reactor and Process Piping: Valve duties exposed to highly corrosive process media requiring Zirconium wetted construction.

• Specialty Chemical Processing: Selected duties involving aggressive media where conventional stainless steels do not provide adequate resistance.

• Corrosive Utility or Recovery Systems: Only where Zirconium compatibility is established for the actual fluid chemistry.

Zr 702 vs Zr 705:

• Zr 702 / UNS R60702: Commercially pure zirconium commonly selected for corrosion resistance in compatible chemical environments.

• Zr 705 / UNS R60705: Zirconium-niobium alloy offering higher mechanical strength than Zr 702 while retaining useful corrosion resistance in compatible environments.

Zirconium Valve Materials:

Material selection should consider fluid chemistry, temperature, pressure, corrosion and sealing requirements:

• Body: Zr 702 or Zr 705 according to corrosion and mechanical requirements.

• Trim: Zirconium or another specified corrosion-resistant material compatible with the complete process chemistry.

• Seat: Metal-seated or design-specific soft-seat configuration within the applicable chemical and temperature limits.

• Packing: Graphite, PTFE or specified sealing material according to temperature and chemical compatibility.

• Fasteners: Stainless steel or specified alloy according to pressure, temperature and external service conditions.

Final material combinations should be selected according to the process medium and operating conditions.

Zirconium Valve Testing:

• Positive material identification where specified.

• Material certification and traceability review.

• Material grade / chemistry verification through certification, PMI or specified inspection requirements.

• Dimensional inspection.

• Surface inspection.

• Hydrostatic body testing.

• Seat leakage testing.

• Functional operation checks.

• Weld inspection where applicable.

• Non-destructive examination where specified.

Pressure and leakage testing may follow API 598 or the applicable valve/project standard. API 6D should only be referenced for relevant pipeline-valve designs.
