2. Design & Construction
The valve is a two-piece, end-entry flanged ball valve with a full-bore design. The body is investment-cast in ASTM A351 Grade CF8 stainless steel, offering good corrosion resistance for general chemical and industrial service. The two-piece body construction allows for inline maintenance of the ball, seats, and stem seals. The valve is equipped with a lever-operated quarter-turn mechanism and an ISO 5211 top mounting pad for direct actuator retrofitting.
Key Features
-
Full port design minimizes pressure drop and allows pigging.
-
Blow-out proof stem.
-
Anti-static device (standard on stainless steel ball valves).
-
ISO 5211 direct-mount top flange for electric or pneumatic actuation.
-
Lockable lever handle (padlock provision).
3. Material Specifications
| Component | Material | Standard / Grade |
|---|---|---|
| Body | Stainless Steel | ASTM A351 CF8 (304) |
| Ball | Stainless Steel | ASTM A351 CF8 / A276 304 |
| Stem | Stainless Steel | AISI 304 / 316 |
| Ball Seats | Reinforced PTFE (RTFE) | — |
| Body Seal | PTFE / Graphite | — |
| Stem Packing | PTFE / Graphite | — |
| Handle | Stainless Steel / Carbon Steel | — |
Note: CF8 (304) offers moderate corrosion resistance. For more aggressive media, CF8M (316) is recommended as an alternative.
4. Dimensional & Flange Data
4.1 General Dimensions
| Parameter | Value |
|---|---|
| Nominal Size | 4″ (DN100) |
| Face-to-Face (ASME B16.10, Class 150) | 229 mm |
| Port Bore | Full port, approx. 100 mm (4″) |
| Top Mounting | ISO 5211 (F07/F10 pattern, 17 mm square stem) |
4.2 Flange Connection — Table E (AS2129)
The valve is supplied with flanges drilled to AS2129 Table E for DN100 nominal bore, as specified in the purchase enquiry.
| Flange Parameter | AS2129 Table E, DN100 |
|---|---|
| Flange Outside Diameter (D) | 215 mm |
| Bolt Circle Diameter (P) | 178 mm |
| Number of Bolt Holes (N) | 8 |
| Bolt Hole Diameter (H) | 18 mm |
| Flange Thickness (T) | 13 mm |
| Nominal Pressure Rating (Table E) | 1400 kPa (approx. 14 bar) at 50°C |
Source: AS2129 Table E slip-on flange dimensions for DN100.
Compatibility Note: AS2129 Table E flanges are dimensionally distinct from ASME B16.5 Class 150 flanges (which use a 190.5 mm bolt circle and 8 × 19.1 mm holes for NPS 4). Verify mating pipe flange compatibility before installation. If the adjacent flange is ASME B16.5 Class 150, a transition gasket or adapter flange may be required.
5. Pressure–Temperature Ratings
The valve is rated to Class 150 per ASME B16.34. The actual allowable working pressure depends on the body material and the seat/seal material.
| Parameter | Rating |
|---|---|
| Maximum Cold Working Pressure (CWP) | 275 PSI (≈ 19.0 bar) |
| Shell Test Pressure | Per API 598 (typically 1.5 × CWP) |
| Seat Leakage Test | Per API 598 |
| Temperature Range (RTFE seats) | −20°C to +200°C |
| Temperature Range (PTFE seats, general) | −29°C to +240°C (pressure-derated at elevated temperature) |
Note: PTFE-based seats are limited by the polymer’s temperature ceiling. Do not exceed +200°C with standard RTFE seats. For higher temperatures, consult the factory for metal-seated or PPL-seated alternatives.
6. Standards & Compliance
| Standard | Scope |
|---|---|
| ASME B16.34 | Valve design, pressure–temperature ratings |
| ASME B16.10 | Face-to-face dimensions (Class 150) |
| AS2129 Table E | Flange drilling (as specified) |
| API 598 | Pressure testing and inspection |
| ISO 5211 | Actuator mounting interface |
7. Testing & Quality Assurance
Each valve is hydrostatically and pneumatically tested prior to shipment in accordance with API 598.
| Test | Medium | Acceptance Criterion |
|---|---|---|
| Shell Test | Water | No visible leakage |
| High-Pressure Seat Test | Water | No visible leakage across seat |
| Low-Pressure Seat Test | Air | No bubble leakage |
8. Operating Data
| Parameter | Value |
|---|---|
| Operation | Quarter-turn lever |
| Maximum Fluid Velocity | 10 ft/s (≈ 3 m/s) recommended for prolonged seat life |
