Product Features

Top-guide sleeve control valve diagram

The HCN Top-Guide Type Porous Cage Control Valve is designed for high pressure drop applications, where erosion and noise are critical concerns. By optimising the internal flow path and adopting advanced throttling design, the valve effectively reduces flow velocity, minimises internal wear, and lowers noise levels. For liquid service, a high-inlet, low-outlet configuration helps dissipate energy within the trim, while for gas service, a low-inlet, high-outlet design allows downstream expansion to reduce pressure and stabilise flow, ensuring reliable performance and extended service life in demanding conditions.
