- Close Die Forging Advantages
- Superior Mechanical Properties – Uniform, dense grain structure without porosity, inclusions, or shrinkage defects.
- High Strength – Ideal for extreme pressures up to Class 2500 (42 MPa).
- Excellent Toughness – A105N normalizing improves low‑temperature impact resistance.
- Leak‑Free Integrity – Forged body eliminates weld seams and casting defects.
- Performance Features
- High Pressure / High Temperature Capability – Designed and tested for Class 2500 service, suitable for steam, boiler feedwater, and high‑pressure hydrocarbon lines.
- RTJ Connection – Ring type joint ensures metal‑to‑metal seal, ideal for high‑pressure and high‑temperature applications where spiral wound gaskets may fail.
- OS&Y (Rising Stem) – Stem threads are outside the pressure boundary, protecting them from media corrosion and allowing visual position indication.
- Hardfaced Trim (Stellite) – Gate and seat rings have Stellite overlay for wear resistance and long cycle life in severe service.
- Flexible Graphite Packing – Provides low emission performance, suitable for steam and thermal cycling.
- Close Die Forged Body – No castings, no porosity; fully traceable material.
- Applications
- Power plants (high‑pressure steam, boiler isolation)
- Oil & gas production (wellheads, manifold, high‑pressure pipelines)
- Refineries and petrochemical plants (high‑temperature hydrocarbon service)
- Hydraulic systems (extreme pressure)
- Chemical processing (with appropriate material upgrade to stainless or alloy)
- Testing & Compliance
Test | Standard / Requirement |
Shell Test | 1.5 × Class 2500 (63 MPa / 9135 psi) – no visible leakage |
Seat Test | 1.1 × Class 2500 (46.2 MPa / 6700 psi) – per API 598 |
Backseat Test | 1.1 × Class 2500 |
Low‑Pressure Seat Test | 0.6 MPa (87 psi) – acceptable leakage per API 598 (Table 5 for gate valves) |
Material Traceability | EN 10204 3.1 (standard for forged components) |
NACE Compliance | Optional (MR0175 / MR0103) |
Marking | Per MSS SP‑25 / API 602 |
- Actuation Options (Beyond Standard Handwheel)
Actuator | Description |
Gear Operator | For easier manual operation at high pressure |
Pneumatic Actuator | Double‑acting or spring‑return for remote on‑off |
Electric Actuator | For automated control with position feedback |
- Ordering Information
Please specify:
- Valve size: 2″
- Pressure rating: Class 2500
- End connection: RTJ (ring type joint)
- Body material: A105N / F22 / F316
- Trim: API 602 Trim 8 (13Cr + Stellite) or other
- Operation: Handwheel / Gear / Pneumatic / Electric
- Special requirements: NACE MR0175, low‑emission packing, positive material identification (PMI), etc.
Notes:
- Close die forging ensures the highest integrity for Class 2500 service. A105N provides good toughness at low temperatures.
- RTJ gaskets (e.g., oval or octagonal rings) are required for assembly – not included with valve unless specified.
- Dimensions and weights are typical; final values depend on manufacturer and specific design (e.g., full bore or reduced bore).
- For high‑temperature applications above 425°C, upgrade to F22 (chrome‑moly) or F91 material.
