Product Overview
This pressure-seal cast steel gate valve uses an integrally cast body for industrial pipeline isolation. The original product information highlights castability, structural rigidity and cost advantages for production.
During operation, the parallel gate moves between the seats to open or isolate the passage. Spring-preloaded sealing supports the stated sealing performance, while Class 900 and higher ratings use the listed self-sealing structure.
The broad visible size and pressure ranges, material options and actuation choices support engineering review for petroleum, chemical, power and high-temperature or high-pressure projects.
- Integral Cast Body: Provides the listed rigidity and production advantages.
- Spring-Preloaded Sealing: Supports reliable sealing performance.
- High-Pressure Configuration: Self-sealing construction is stated for Class 900 and above.
