  1. 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.
  1. Performance Features
  1. High Pressure / High Temperature Capability – Designed and tested for Class 2500 service, suitable for steam, boiler feedwater, and high‑pressure hydrocarbon lines.
  2. RTJ Connection – Ring type joint ensures metal‑to‑metal seal, ideal for high‑pressure and high‑temperature applications where spiral wound gaskets may fail.
  3. OS&Y (Rising Stem) – Stem threads are outside the pressure boundary, protecting them from media corrosion and allowing visual position indication.
  4. Hardfaced Trim (Stellite) – Gate and seat rings have Stellite overlay for wear resistance and long cycle life in severe service.
  5. Flexible Graphite Packing – Provides low emission performance, suitable for steam and thermal cycling.
  6. Close Die Forged Body – No castings, no porosity; fully traceable material.
  1. کاربردها
  • 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)
  1. 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

  1. Actuation Options (Beyond Standard Handwheel)

Actuator

توضیحات

Gear Operator

For easier manual operation at high pressure

Pneumatic Actuator

Double‑acting or spring‑return for remote on‑off

Electric Actuator

  1. 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.
