Application scenarios

Each scenario summarizes an approved application and a recommended product family. Scenario data informs decisions — it is not a promise for other operating conditions.

valves-oilgas

Valve Packing and Flange Live Loading

阀门填料与法兰活载荷通常需要定制堆叠；先按密封/活载荷目标预选补充规格族。

Load: 按活载荷目标与螺栓预紧余量确定
Travel: 补偿填料松弛与热循环行程

REVERSE SELECTION

Select by operating requirements

Enter the target load, total travel and installation constraints. The system compares published specifications using the A-L formula. Results are candidates for engineering review, not final approval.

ENGINEERING CANDIDATES

Candidate solutions

Awaiting input

Engineering boundary

Candidate ranking uses an elastic A-L comparison with E = 206,000 MPa and ν = 0.3. Preload, friction, guide clearance, tolerances, plasticity, fatigue life and safety factors require detailed calculation, FEM or experimental verification.
