Maria Valve
1 / 5
The valve shape is compact and lightweight, providing high performance and large capacity. It is an ideal general regulating valve for common fluid mediums in industrial control systems. For operations up to 250°C, the normal structure is sufficient; however, for temperatures exceeding 250°C, a Heat Radiator and specialized heat treatment for the trim are required.
Available Types: Standard Type, Regulating Cutting Type, Bellow Seal Type, and Jacket Type.
