Selecting ball valve manufacturers needs to audit API 6D certification, ISO 9001 system, focus on checking valve body material (such as ASTM A105), pressure rating
As ISO 9001 certified factory, we focus manufacturing floating ball valves. Specifications DN15-DN300, pressure 150-600LB. Every unit through “2 times strength + 3 times sealing”
As a reliable industrial valve supplier, we provide API 6D and CE certified valve products, ensuring compliance with international standards. All valves before shipment undergo
Our wholesale 6D ball valves include cast steel and forged steel materials, widely used in petroleum, chemical, energy and other industries. All ball valves comply
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
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
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;
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
