|---|---|
Dual Isolation Function: The valve is internally designed with two independent sealing balls, enabling dual isolation to ensure no medium leakage during maintenance or overhaul.
Bleed Function: Equipped with one bleed port, which can safely discharge residual media in the pipeline after isolation, preventing media accumulation and pressure buildup.
Floating Ball Design: The ball can float freely under the pressure of the medium, fitting tightly with the valve seat to form an excellent sealing effect, and also has an automatic pressure relief function.
Fire Safety Design: Complies with API 607 standards. Even in case of fire, the valve can still maintain sealing performance to prevent safety accidents caused by medium leakage.
Anti-Static Device: Built-in anti-static device effectively prevents static accumulation, reducing the risk of fire and explosion.
Flange Connection: Multiple flange connection methods are available, conforming to ASME B16.5 standards, ensuring installation reliability and compatibility.
Compact Design: 3-piece structure reduces installation space and weight, while lowering installation costs.
