Technical Specifications

Product Overview

High-Performance Industrial Ball Valve

This high-temperature wear-resistant ball valve is engineered for demanding industrial applications, including chemical, petroleum, petrochemical, power, mining, and metallurgy sectors. It features an integrated downstream seat design that ensures rigidity and prevents media accumulation, while the upstream seat utilizes a corrosion-resistant elastic seal to prevent valve lock-up at high temperatures. The unique arc seat design provides excellent sealing and self-grinding capabilities, significantly extending the service life of the valve under harsh conditions involving erosion, high pressure, and particle-laden media.
