This 3 ball valve stainless steel adopts precision casting and machining. Its thickened valve body withstands pipeline pressure shocks and mechanical vibration. The finely polished ball core reduces fluid friction and fouling for unimpeded medium flow. High wear-resistant, anti-aging seals deliver reliable zero-leakage performance at rated pressure. Standard bore and threaded connections enable fast assembly and disassembly. The full stainless steel construction offers superior rust and corrosion resistance, sustaining stable performance indoors, outdoors and in mildly corrosive industrial settings for prolonged service life.
Product Material
Valve Body
304 / 316 stainless steel, integral forging, dense texture, free of sand holes and porosity. It delivers excellent rust resistance, oxidation resistance and tolerance to mild corrosive media.
Ball & Stem
Solid stainless steel with mirror polishing. Smooth surface reduces operating torque, resists wear and prevents jamming under frequent switching.
Seat Seal
Standard PTFE. Optional EPDM or NBR for different temperature and medium requirements. PTFE features low friction, high temperature resistance and reliable zero-leakage performance.
Gaskets & Fasteners
Stainless steel gaskets, bolts and retaining pins. Avoid rust and loosening in humid environments, maintaining stable assembly pressure.
Customization Capability
We provide flexible customization services for 3-piece stainless steel ball valves. Adjustable options include thread specifications, sealing materials, handle types, surface treatment, laser marking and packaging. We can adjust products to meet special pressure, temperature and medium requirements, and support OEM & ODM orders to match your brand and project demands.
FAQ
Q: What are the advantages of integral forging compared with cast valve body?
A: Forged stainless steel bodies feature denser internal structure, fewer internal pores and stronger pressure resistance. Cast bodies are more prone to tiny sand holes. For high-pressure and critical industrial pipelines, forged versions are more reliable
Q: What kind of medium easily damages PTFE valve seats?
A: Strong oxidizing agents, molten alkali, some strong solvents and high-temperature saturated steam will accelerate aging or erosion of standard PTFE seats. Please inform us of special media for customized sealing solutions.
Q: Can this 3 ball valve stainless steel be used for intermittent frequent switching work?
A: Yes. The polished ball and PTFE seat combination is suitable for intermittent frequent on-off. If switching frequency is extremely high, we can optimize surface treatment and sealing materials.
Q: What maintenance work needs to be done for the three-piece stainless steel ball valve in long-term service?
A: Regularly check external leakage at stem packing and bolt connections. Clean sediment inside the valve if the medium contains impurities. Inspect the valve seats for abrasion. Lubricate moving components when operation becomes stiff.
Q: What differences exist between forged and cast 3 ball valve stainless steel in structure performance?
A: Forged valve body has denser internal structure, fewer pores and stronger pressure resistance. Cast body is more cost-effective but may have tiny casting defects. For high-pressure critical pipelines, forged structure is preferred.
