Description
SAMSON Type 3256 Pneumatic Angle Control Valve is an angle-body pneumatic control valve for demanding process service and high differential-pressure configurations. SANTAN supports model confirmation and quotation for new projects, maintenance replacements and engineered packages.
Values below are transcribed from the linked current SAMSON data sheet. Broad family ranges must not be treated as the limits of every order code; final selection depends on the complete configuration and process conditions.
Verified technical specifications
| Nominal size (ANSI sheet) | NPS 1/2 to 12 |
|---|---|
| Pressure rating (ANSI sheet) | Class 150 to 2500 |
| Published temperature envelope | -196 to +550 deg C; configuration-dependent |
| Standard PTFE packing range | -10 to +220 deg C |
| Characteristic | Equal percentage, linear or on/off |
| Rangeability | 50:1 |
Engineering selection checklist
| Process duty | State the fluid or gas, normal and upset conditions, and whether the duty is throttling, mixing, diverting or isolation. |
|---|---|
| Sizing basis | Provide normal, minimum and maximum flow plus upstream and downstream pressure; valve sizing must be checked for the actual service. |
| Mechanical configuration | Confirm nominal size, pressure class, body and trim materials, end connections, packing or bellows requirements. |
| Actuation and fail action | Confirm actuator type, available air supply, required fail-open or fail-close action, and accessory mounting. |
| Documentation | Request the exact SAMSON data sheet, dimensional drawing and configuration-specific approvals for the ordered code. |
Industry application guidance
The Type 3256 is relevant to process engineering applications with high industrial requirements. Before ordering, engineers should review pressure-temperature limits, noise, cavitation or flashing risk, materials compatibility, actuator sizing and applicable project documentation.
