2″-2500LB Inconel 625 Lift Check Valve

TECHNICAL DATA SHEET

Product: Lift Check Valve
Tamaño: 2 inch (DN50)
Clase de presión: Class 2500
Material del cuerpo: Inconel 625 (UNS N06625)
End Connections: Flanged – ASME B16.5 Class 2500
Design: Lift Check (Piston Type)

1. Basic Specifications

2. Main Features

• Lift Check Design: Disc lifts vertically off the seat under forward flow and drops back when flow reverses, providing reliable backflow prevention.
• Inconel 625 Construction: Full Inconel 625 body and trim offer exceptional resistance to pitting, crevice corrosion, stress corrosion cracking, and high‑temperature oxidation. Ideal for sour service (NACE MR0175), seawater, and aggressive chemical environments.
• High‑Pressure Capability: Class 2500 rating with flanged ends suitable for ultra‑high‑pressure systems.
• Pressure Seal Bonnet: Ensures leak‑tight performance under fluctuating high temperatures and pressures.
• Renewable Seat & Disc: Seat and disc hardfaced with Stellite 21 for extended service life and ease of maintenance.
• Compact Design: Lift check valves offer a shorter face‑to‑face length compared to swing check valves.

3. Material List (Specified Configuration)

Note: Full Inconel 625 construction avoids galvanic corrosion issues common with dissimilar materials.

4. Dimensions & Structural Data (Flanged Ends)

Note: Final dimensions to be confirmed by manufacturing drawings.

5. Design & Testing Standards

6. Inconel 625 Material Advantages

7. Operating Guidelines

• Orientation: Lift check valves are typically installed in horizontal pipelines with the bonnet vertical, or in vertical lines with flow upward.
• Cracking Pressure: Standard cracking pressure is typically 0.5 – 1.0 psi (0.03 – 0.07 bar). Spring‑assisted designs are available for vertical installation or low‑pressure applications.
• Flow Characteristics: Minimal pressure drop when fully open, as the disc lifts completely out of the flow path.

8. Typical Applications

• Subsea & Offshore: High‑pressure subsea manifolds, Christmas trees, and topside piping in seawater service.
• Sour Service: Oil & gas production with high H₂S and CO₂ content (NACE MR0175 compliance).
• Nuclear Power: High‑temperature steam and feedwater systems.
• Chemical Processing: Corrosive chemical plants handling acids, chlorides, and high‑temperature fluids.
• Hydrogen Service: High‑pressure hydrogen systems requiring nickel alloy construction to prevent hydrogen embrittlement.
