Carbon Steel vs Stainless Floating Valve | WCB vs CF8M, Media Suitability, Cost
Carbon steel (WCB) floating ball valve high strength, suitable for ≤425℃, non-strong corrosive media (such as water, steam, oil), cost about 20–40% lower than stainless steel. Stainless steel (CF8M, ≈316) contains 2–3% molybdenum, resistant to Cl⁻ corrosion, suitable for seawater, acid and alkali, temperature generally ≤200℃. When selecting: look at media corrosivity (pH, Cl⁻ppm), temperature […]
Fire Safe Floating Ball Valve | API 607, Anti-static, Petrochemical Pipelines
Fire-safe floating ball valve complies with API 607 standard, possesses fire-safe structure design, and after the sealing material is burned out, it can still maintain a leakage rate of ≤0.1% through the metal seal. The valve body is equipped with an anti-static device (resistance ≤10Ω) to avoid static electricity accumulation triggering an explosion. Suitable for […]
Floating vs Trunnion Ball Valve | API 6D, Pressure Limits, Selection Guide
Floating ball valves are suitable for medium and low pressure, relying on medium pressure to press tightly for sealing, structure is simple, cost is low; but torque is large at large diameters. Trunnion ball valves are supported by upper and lower bearings, suitable for high pressure and large diameters, operating torque is reduced by 30%~50%. […]
How Floating Ball Valves Work | Sealing Mechanism, Flow Control, Applications
Floating ball valve through sphere between valve seats micro-floating realizes sealing, medium pressure (such as 0.6–4.0 MPa) pushes sphere pressing tightly downstream valve seat, forming self-sealing structure. When opening rotate valve stem 90°, through-hole aligning realizes full bore (flow resistance coefficient Cv high); when closing cuts off flow path. Commonly used PTFE valve seat withstands […]

Why More Global Buyers Are Working with a China Ball Valve Manufacturer Directly | lower cost, faster response, better customization
More and more global buyers directly dock with Chinese ball valve manufacturers, mainly because cost can be reduced by 20%–40%, saving middle trade links; Response time shortens from 3–5 days to within 24 hours; support customization according to drawings or working conditions, proofing cycle is only 7–15 days. Suggest through factory official website or Alibaba […]
Ordering Custom Forged Ball Valves? Confirm These Details Before Production Starts ? | drawing approval, marking request, inspection scope
Drawing size tolerance (±0.05mm), material standard (such as ASTM A105), pressure class (Class 150–2500), marking content and position (marking depth 0.3mm), inspection scope (100% water pressure + 10% spot check RT), and sign drawing and inspection plan after then can put into production. drawing approval Size & Flange Connection ASME B16.10 specification divides long and […]
Soft Seated or Metal Seated Forged Ball Valve: Which Option Fits Your Application | sealing method, media condition, temperature range
Soft seated ball valves are suitable for clean media, temperature ≤200°C, leakage class can reach ANSI Class VI; metal seated are suitable for particle-containing or high-temperature conditions (≤550°C), erosion resistant but leakage class is generally Class IV. Selection should be based on media particle content, temperature range, and opening/closing frequency, and combined with sealing surface […]
