The Submerged Welded Ball Valve is a pipeline control device featuring a full-welded structure, primarily used for fluid control in underground pipeline systems. It boasts features such as corrosion resistance, reliable sealing, and easy installation.

Structural Features

‌Full welding process: The valve body and pipe are connected by welding, without threaded or flanged structures, eliminating the risk of external leakage.‌

Material Selection: Common materials include carbon steel (such as WCB, 304/316 stainless steel), suitable for mediums like oil, gas, and water.

Sealed Design: Comprises a combination of PTFE sealing ring and spring, with double-sealed valve rod design. Operating temperature range: -29°C to 200°C.

Technical Specifications

Pipe Size Range: DN15 to DN600 (varies by manufacturer's model)

Pressure Rating: Up to PN 6.4 MPa (pressure range varies slightly by model)

‌Drive Mode: Supports manual, pneumatic, and electric drives, etc.‌

Application Scenario

Widely used in urban gas and heating networks, petrochemicals, power, and other fields, particularly suitable for long-distance pipeline projects that require direct burial underground.
