KS High Temperature

Ramén KS- High Temperature

– Metal seated control valve, DN 25 – DN 300

This model, a special execution of Ramén KS, is a tailored control valve for high temperature applications, especially for steam control. This is a modified version of KS-1B, designed to withstand temperature as high as +250°C while maintaining the control precision and reliability. This is thanks to carefully selected materials such as stainless steel body, Stellited metal seat, hard chromed ball sector, high grade EPDM-90 O-ring and MP bearing.

This control valve assemby include high temperature pneumatic actuator to withstand the heat through radiation. This combination enables our valves to resist tough operability, maximizing the equipment uptime and minimizing the process unit downtime.
