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
① Products ones consistencies: Requires asks batchs times matchs grids rates ≥ 98%, builds sets comes materials and completes products doubles checks (AQL1.0); ② Communications
① Product consistency: requires batch qualified rate ≥98%, establishes incoming material and finished product double inspection (AQL1.0); ② Communication efficiency: within 48 hours technical reply,
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
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
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
API forged ball valve selection needs to satisfy API 6D standard (covering 150–2500 pressure levels), and provide MTC, pressure test reports and other complete documents;
Reliable forged steel ball valve export factory look at three points: ① export experience ≥ 5 years, annual shipment ≥ 5000 units; ② Quality control:
Materials: A105 stainless steel approximately ¥120-200 per unit, 316 stainless steel ¥300-600; Quantity: Price decreases by 5%-10% for 100 units, and by 15%-25% for 1000
Forged ball valve because of overall forging structure dense, strength increases about 20%-30%, pressure resistance can reach Class 1500 above, leakage rate is lower than
