Design Basis
In A105N PTFE Seated Floating Ball Valve Class 800, the Floating Ball 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 A105N PTFE Seated Floating Ball Valve Class 800, the pressure boundary is A105N. Normalized forged carbon steel used in compact forged pressure boundaries. Because this valve is Class 800 with Flanged / SW / NPT, verify the material condition, trim compatibility, bolting and any PMI/NDE or corrosion-control requirement as one package.
Pressure Class and Piping Interface
For A105N PTFE Seated Floating Ball Valve Class 800, the specified rating is Class 800 and the piping interface is Flanged / SW / NPT. Compact forged-valve pressure class typically associated with socket-weld or threaded piping systems. Flanged, socket-weld and threaded variants suit different piping layouts and installation practices. 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 A105N PTFE Seated Floating Ball Valve Class 800, the listed sealing basis is PTFE. Ptfe-based seating provides low-friction soft sealing where pressure, temperature and chemistry remain within the selected polymer limits. Confirm leakage acceptance, pressure/temperature limits and cycling together with the Class 800 loading and the selected Lever / Gear / Actuator operating method.
Operation and Actuation
For A105N PTFE Seated Floating Ball Valve Class 800, operation is Lever / Gear / Actuator. Gear or powered actuation should be selected from the valve torque curve, maximum differential pressure, operating frequency and required closing time. The final operator or actuator basis should use the actual size, maximum differential pressure, PTFE friction/seating behavior and required operating or emergency time.
Service Conditions
No service qualifier is fixed by the product name, so A105N PTFE Seated Floating Ball Valve Class 800 should be released only after the actual fluid, temperature range, pressure cases, cycling and special service requirements are known.
Inspection and Testing
For A105N PTFE Seated Floating Ball Valve Class 800, tie MTC/heat traceability, dimensional inspection, PMI/NDE where specified, shell/seat testing, coating checks, witness points and final records to the approved API 608 datasheet and ITP.
Documents Before Release
The manufacturing release for A105N PTFE Seated Floating Ball Valve Class 800 should reference the approved GA, material/trim schedule, seat/seal definition, operator or actuator data, test scope and required final documentation.
