Design an industrial valve to handle mineral oil service under the following operating conditions:
Operating Parameters:
Fluid: Mineral oil (ISO VG 32–68 typical industrial oil)
Operating Pressure: 100 PSI (6.9 bar)
Flow Rate: 5 liters per second
Temperature Range: 10°C to 80°C
Continuous duty operation
Design Requirements:
1. Select suitable valve type (ball / gate / globe / check / butterfly) and justify selection.
2. Determine nominal pipe size based on flow rate and acceptable velocity (1–3 m/s for
oil).
3. Provide Cv calculation and valve sizing methodology.
4. Recommend body material suitable for oil service.
5. Recommend seat and seal materials compatible with hydrocarbons.
6. Specify pressure class (ANSI / ASME).
7. Define end connections (flanged / threaded / welded).
8. Provide wall thickness estimation as per ASME B16.34 or relevant code.
9. Suggest actuation method (manual / pneumatic / electric).
10. Include safety factors and design margin.
11. Provide a brief GA (General Arrangement) description with key dimensions.
12. Mention applicable standards (ASME, API, ISO).
Deliverables Required:
Technical specification sheet
Valve sizing calculations
Material selection table
Cross-sectional design description
Compliance standards list
