The Type 3291 seat retained globe control valve is designed for general service applications up to the limits of the ANSI 900 pressure class rating. These general service applications include process events such as erosion, abrasion, corrosion, cavitation, and flashing found in most process control industries.
The Type 3291 control valve has several standard options such as temperature extensions, metal bellows seals, heating jacket, high performance metal sealing trim, soft sealing trim, noise attenuation and cavitation prevention trim sets, etc. In addition to these options the valves can be specialized to meet the exact process needs such as NACE version for sour gas service, cleaned for specific service (e.g. Oxygen, Chlorine, High Purity, etc.).
The Type 3291 can be assembled with a pneumatic, electric, hydraulic, or electro-hydraulic actuator also offered by SAMSON to complete the control valve construction. These control valves are designed according to the modular assembly principle, can be equipped with SAMSON actuators and valve accessories such as positioners, limit switches, and solenoid valves.
