Definition: The national standard floating ball valve is a valve that complies with the national standard (GB). Its core structure is a floating ball (without a fixed support shaft), which relies on the pressure of the medium to push the ball to press the outlet valve seat and achieve sealing.

Core features:

Structural design:

The sphere can float freely and be connected to the handle/drive device through the valve stem to achieve 90 ° rotation opening and closing;

Adopting a double line sealed valve seat, combined with spring preload and medium pressure to enhance sealing performance;

Configure anti-static, fireproof, and valve stem anti flying structures to enhance safety.

Performance parameters:

Pressure range: covering 0.6~42.0MPa;

Temperature range: -196 ℃~550 ℃, suitable for ordinary or corrosive media (such as water, oil, natural gas, acid and alkali, etc.);

Low flow resistance full diameter: With low fluid resistance, it is suitable for high flow scenarios such as petroleum and chemical industries.

Materials and standards:

The valve body material includes cast steel, stainless steel, etc., and the valve seat can be selected from polytetrafluoroethylene (PTFE) or metal hard seal;

Compliant with national standard GB and international standards (such as DIN, API), compatible with flange, thread and other connection methods.

Typical applications: Medium and low voltage pipelines in petrochemical, natural gas transportation, power systems, etc., especially suitable for scenarios containing hydrogen sulfide and highly corrosive media.
