Design Basis
In Bellows Seal WCB Globe Valve Class 150, the Bellows Seal Globe Valve construction determines the closure support, body arrangement and maintenance approach. Confirm bore or flow path, body joint, stem/shaft retention, seat support, anti-blowout features where applicable and access requirements against the approved GA.
Pressure-Boundary Material
For Bellows Seal WCB Globe Valve Class 150, the pressure boundary is WCB. Cast carbon steel for general hydrocarbon and process pressure boundaries. Because this valve is Class 150 with Flanged, verify the material condition, trim compatibility, bolting and any PMI/NDE or corrosion-control requirement as one package.
Pressure Class and Piping Interface
For Bellows Seal WCB Globe Valve Class 150, the specified rating is Class 150 and the piping interface is Flanged. Lower-pressure industrial piping where material-specific pressure-temperature limits still govern. The flange standard, facing, drilling, gasket and face-to-face dimensions must align with the mating piping. Final dimensions and pressure-temperature suitability must therefore be checked against the selected material and design temperature, not inferred from class alone.
Seat and Seal Arrangement
For Bellows Seal WCB Globe Valve Class 150, the listed sealing basis is Metal Seat. Metal seating shifts the design toward hardfacing/coating, lapping, higher torque and wear control rather than polymer-seat compliance. Confirm leakage acceptance, pressure/temperature limits and cycling together with the Class 150 loading and the selected Handwheel operating method.
Operation and Actuation
For Bellows Seal WCB Globe Valve Class 150, operation is Handwheel. Manual handwheel/gear selection should keep rim pull and operating effort practical at the maximum specified differential pressure. The final operator or actuator basis should use the actual size, maximum differential pressure, Metal Seat friction/seating behavior and required operating or emergency time.
Service Conditions
No service qualifier is fixed by the product name, so Bellows Seal WCB Globe Valve Class 150 should be released only after the actual fluid, temperature range, pressure cases, cycling and special service requirements are known.
Inspection and Testing
For Bellows Seal WCB Globe Valve Class 150, tie MTC/heat traceability, dimensional inspection, PMI/NDE where specified, shell/seat testing, coating checks, witness points and final records to the approved API 623 / ASME B16.34 datasheet and ITP.
Documents Before Release
The manufacturing release for Bellows Seal WCB Globe Valve Class 150 should reference the approved GA, material/trim schedule, seat/seal definition, operator or actuator data, test scope and required final documentation.
