Brass Metal Seal Design
Better high-temperature resistance compared with rubber seals
Stable sealing performance during long-term use
Low Flow Resistance
Full bore design
Reduced pressure loss, suitable for high-flow pipelines
Long Service Life
Brass material resists scaling and oxidation
Low maintenance frequency
Wide Application Range
Water systems
Steam pipelines
Oil and general industrial media
(For corrosive media, special material treatment is recommended)
Working Principle
The valve operates by rotating the handwheel to drive the stem and gate plate up or down:
When fully opened, the flow passage is straight and unobstructed
When closed, the copper alloy sealing surfaces fit tightly to prevent leakage
Simple structure ensures stable operation and easy maintenance
This design makes the valve suitable for frequent opening and closing in industrial and building systems.
