Product Overview
WUYI's double-sealed cage control valves feature cage-guided, pressure-balanced plugs.With a dual metal-seal design, they are suitable for applications with low leakage requirements and offer a wider operating temperature range.
Key Features
WUYI's valves feature a pressure-balanced plug, requiring low actuating force even under high differential pressure. Suitable for fluid control in medium-to-low temperature and pressure pipelines with high dynamic stability requirements. They offer excellent sealing, large allowable pressure difference, and high stability with a compact, cage-guided structure. Internal parts can be replaced quickly in-line, improving maintenance efficiency.
