A full-welded ball valve with handle is a fluid control device featuring a full-welded structure, operated through a handle for on/off control. It boasts high sealing, corrosion resistance, and pressure resistance, and is widely used in industrial sectors such as petrochemicals, urban heating, and fire water supply.

Structural Features

The fully welded structure connects the valve body and flange directly through precise welding techniques, eliminating the risk of leakage caused by traditional threaded or flanged connections, ensuring long-term stability. The valve body is made of carbon steel, with critical internal components (such as the ball, seat, and stem) optimized for enhanced sealing performance and corrosion resistance.

Performance Advantages

‌Bidirectional Sealing: The double-sealed design can withstand fluid pressure from both directions, maintaining a stable seal even under high temperature and high-pressure conditions.‌

‌Maintenance Convenience: Sealing components can be replaced without removing the flange, significantly reducing maintenance costs and time.‌

Material Durable: Made of high-strength alloy steel and corrosion-resistant materials (such as 304/316 stainless steel), suitable for various medium environments.

Fluid Control: Optimized channel design minimizes pressure loss, suitable for high-precision adjustment scenarios.

Applicable Scenarios

Ideal for pipeline systems requiring high reliability and long-term stability in urban gas, petrochemical, fire-fighting water supply, heating systems, etc., with a service life of up to 20 years.
