CNC Machining: All components undergo digital CNC for critical tolerances, smooth surfaces, and leak-proof seat interfaces.
Polishing & Surface Finish: Automated & manual polishing to RA≤0.8μm reduces corrosion risk and flow resistance.
Seat & Seal Installation: PTFE, PEEK, or graphite seats installed based on temp/chemical compatibility.
Assembly & Tightening: Three-piece design is assembled with precision torque spec to ensure concentricity and end-load strength.
Testing & Certification: 100% hydrostatic (shell & seat), pneumatic, and fire-safe testing as per API 598/ISO 5208.
Marking & Packaging: Permanent laser etching of code, traceability, and anti-corrosive export packaging.

This rigorous process ensures stainless steel ball valve service life & compliance even in aggressive environments like petrochemical plants and offshore installations.

Application Scenarios and Advantages of Stainless Ball Valves

Stainless ball valves are indispensable in critical fluid handling due to their anti-seizing operation, compactness, fire-safe design, and zero-leakage seat. The 3PC Dn-50-600mm Stainless Steel Ball Valve delivers unmatched operational reliability in:

Petrochemical & Refining: Handles sour, acidic, and high-P&T media per ISO15156 — 316/316L construction resists hydrogen cracking.
Power Generation: High temperature stainless steel ball valves safely isolate superheated steam and boiler chemicals.
Water/Wastewater: Non-corrosive, hygienic construction fits potable, desal, and effluent streams.
Food & Pharma: FDA-compliant seat options, electropolish finish (-0.8μm) minimize contamination risk.
Mining & Minerals: Abrasion-resisting balls and PTFE seats optimize duty cycles in slurry lines.

FAQ: Technical Terms about Stainless Ball Valves

Q1: What is the difference between CF8, CF8M, SS304, and SS316 in ball valves?: CF8/SS304 are basic austenitic stainless grades, suitable for water and neutral fluids. CF8M/SS316 contains molybdenum, offering superior resistance to chlorides, acids, and marine environments—preferable for harsh/chemical applications.
Q2: What does the term "fire-safe design" in stainless ball valves mean?
