SAMSON, HEAVY DUTY GLOBE CONTROL VALVE, Model: 3251

OVERVIEW:

The Type 3251 threaded seat globe control valve is designed for general service applications up to the limits of the ANSI 2500 pressure class rating. These general service applications including process events such as erosion, abrasion, corrosion, cavitation, and flashing found in most process control industries.

The Type 3251 control valve has several standard options such as temperature extensions, metal bellows seals, heating jacket, high performance metal sealing trim, soft sealing trim, ceramic 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 3251 can be assembled with a pneumatic, electric, hydraulic, or electro-hydraulic actuator also offered by the SAMSON group to complete the control valve construction. These control valves are designed according to the modular assembly principle, can be equipped with SAMSON GROUP actuators and valve accessories such as positioners, limit switches, and solenoid valves.
