Samson Valve 3241 Pneumatic Control Valve ANSI

Samson Valve 3241 Pneumatic Control Valve ANSI is designed for general service applications up to the limits of the ANSI 300 pressure class rating. These general service applications include process events such as erosion, abrasion, corrosion, cavitation, and flashing found in most process control industries.

Samson Valve 3241 Pneumatic Control Valve ANSI 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. 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.), or the pressure swing adsorption (PSA) design.

Samson Valve 3241 Pneumatic Control Valve ANSI 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.

Samson Valve 3241 Pneumatic Control Valve ANSI, modular design with fewer parts required as well as commonality of parts for different sizes. Up to 11 Cv coefficients available in steps of 1.6 for each valve size. Only four parts required to rebuild the valve: the seat, plug, body gasket, and packing. TA-Luft / EPA Low Emissions self-adjusting PTFE V-ring packing as standard. Bonnet, yoke, and body made of the same material for process compatibility.

Samson Valve 3241 Pneumatic Control Valve ANSI can be combined with the following actions:

3271 Pneumatic actuator

special function: Single-acting linear actuator with rolling diaphragm and internal spring、Diaphragm area from 120 to 2×2800 square centimeters, Low overall height, Strong thrust at high stroke speed, Low friction, Various worktable ranges by changing the number of springs or their compression, No special tools are needed to change the range of the worktable or reverse the direction of action.

3277 Pneumatic actuator

special function: Single-acting linear actuator with rolling diaphragm and internal spring、The diaphragm area is from 120 to 750 square centimeters, Install the accessory directly on the additional bracket through the hidden travel sensor, Low overall height, Strong thrust at high stroke speed, Low friction, Various worktable ranges by changing the number of springs or their compression, No special tools are needed to change the range of the worktable or reverse the direction of action.

3273 Handwheel

special function: Spindle actuator with non-rising handwheel, handwheel diameter 180 or 250 mm, Low overall height, Simple connection of valve, The locking mechanism can ensure that the position of the valve stem will not be adjusted accidentally.
