290 Series Control Valves

SAMSON control valves Series 290 Control Valves

Series 290 Control Valves are primarily used in the petrochemical industry and process engineering due to their maintenance-friendly properties. The seat is clamped into the valves to facilitate maintenance.

Series 290 Valves are only available in ANSI versions in valve sizes NPS ½ to 8 and pressure ratings of Class 150 to 900. A bellows seal or insulating section allows the valves to be used in temperature ranges between –196 and +450 °C (–325 and +842 °F) depending on the material used.

Additional equipment includes flow dividers, heating jackets and balanced plugs. Furthermore, Series 290 Valves can be designed to meet NACE requirements for sour gas.
