FAQs of Stainless steel 2piece ball valve
1. What is the two-piece ball valve core material?
Valve bodies and valve covers are made of 304/316/316L stainless steel.
304 grade: Chromium content 18.0%–20.0%, nickel content 8.0%–12.0%, carbon content ≤0.08%.
316 grade: Based on 304, it adds 2.0%–3.0% molybdenum.
316L grade: Carbon content ≤0.03%. It has much stronger intergranular corrosion resistance.
The ball core is made of 316 stainless steel. Its hardness is HRC28–32. The valve seat uses standard PTFE (polytetrafluoroethylene). Every batch comes with a material spectrum analysis report (MTC). We support third-party component testing from SGS or BV. Any products with excessive deviation can be returned unconditionally.

9. Can third-party inspections be arranged for the stainless steel 2-piece ball valve?
We support cooperation with multiple types of third-party testing institutions.
Just tell us your needs — whether you’re a distributor or a buyer. We can connect you with international authoritative testing bodies. SGS, BV, and TÜV are all options. We can also work with domestic third-party labs designated by you.
Test items fully cover all core performance indicators of stainless steel two-piece ball valves. Here are the key ones:
Material composition testing. We use spectrum analysis to check the purity of 304/316L stainless steel in valve bodies and balls. This ensures the material meets drinking water sanitary standards or industrial corrosion resistance requirements.
Dimensional accuracy testing: We verify key parameters. Things like caliber, wall thickness, thread tolerance, and handle installation size. It guarantees the valve fits standard pipelines.
Sealing and pressure testing. We run pressure tests at 1.5 times the working pressure. We check the air-tightness and water-tightness of the valve body and seat. No leakage is allowed.
Service life and operation testing. We test the valve’s opening and closing life — it’s at least 100,000 times. We also check the handle operation torque. This verifies long-term stable performance.
For special scenarios, such as coastal areas or chemical industries, we conduct salt spray tests. The results meet the corrosion resistance time standard you require.
10. Are stainless steel 2-piece ball valves individually tested or batch tested?
We employ a dual inspection model, utilizing 100% full inspection for key performance indicators and batch sampling for basic parameters. Here are the details:
Core Performance Indicators: 100% Full Inspection, No Defective Units
Each valve undergoes a pressure test at 1.5 times the working pressure. The pressure holds for 30 minutes. We check the valve body and seat for air and water tightness. No leakage is allowed.
We test the handle opening and closing torque manually. It must run smoothly with no stuck points. The opening and closing angles must be accurate and in place.
After passing the test, every qualified valve gets a unique pass label and traceability code. We record the tester, test time, and test data. This achieves full traceability for each unit.
Basic Parameter Indicators: Batch Sampling, Control Overall Consistency
For basic indexes such as material composition, size accuracy, and surface technology, we conduct batch sampling inspections. The sampling rate strictly follows ISO 2859 standards.
Size testing: Every 1000 units counts as one batch. We randomly select 5% of the samples. We test parameters like caliber, wall thickness, and thread tolerance. All must comply with international standards such as BSPP/NPT.
Surface inspection: We sample and check the valve surface polishing and passivation effect. No scratches, burrs, or rust spots are allowed. The salt spray test time must meet the required standard.
