The ZSH(DR)OG series high-platform ball valve complies with ISO 5211. Its square mounting flange is integrally cast with the valve body and rises above the end-flange outside diameter, allowing the actuator to be mounted directly without a bracket or coupling shaft. This improves rigidity, saves space and provides a clean appearance. The valve has low flow resistance and self-cleaning sealing surfaces, with a compact body and small footprint. It is widely used for tight shutoff in petroleum, chemical, municipal water supply and drainage, food and pharmaceutical, marine and related industries.
