DN25-PN100 2-Piece Metal Seated Ball Valve

TECHNICAL DATA SHEET

Product: 2-Piece Metal Seated Ball Valve
Size: DN25 (1 inch)
Pressure Rating: PN100 (Class 600)
Body Construction: 2-Piece, Floating Ball
Seat Type: Metal‑to‑Metal
End Connections: Flanged (EN 1092‑1 / ASME B16.5)

1. Basic Specifications

2. Main Features

• Metal‑to‑Metal Seating: Ball coated with tungsten carbide (WC) or Stellite; seat hardfaced with Stellite alloy. Provides exceptional wear, erosion, and high‑temperature resistance.
• 2-Piece Body: Compact construction, easy maintenance. The body joint is secured with high‑strength bolting.
• Floating Ball Design: Under line pressure, the ball shifts slightly against the downstream seat, ensuring tight shut‑off under high differential pressure.
• Blowout‑Proof Stem: Stem is designed to prevent ejection under pressure.
• Fire Safe: Metal seated construction inherently meets fire‑safe requirements without additional coatings.
• Spring‑Loaded Seats (Optional): Pre‑loaded seats maintain continuous contact with the ball, ensuring reliable sealing even at low pressure or under thermal cycling.

3. Material List (Recommended High‑Temperature / High‑Pressure Configuration)

Note: NACE MR0175 compliant materials available for sour service.

4. Dimensions & Structural Data (Flanged Ends)

Note: Final dimensions to be confirmed by manufacturing drawings.

5. Design & Testing Standards

6. Metal Seated vs. Soft Seated Comparison

7. Operating Torque & Actuator Sizing

• Higher Torque Requirement: Metal seated valves typically require higher torque than soft seated valves due to metal‑to‑metal contact and spring preload.
• Floating Ball Effect: In floating ball designs, torque increases with differential pressure as the ball is pressed against the downstream seat.
• High‑Temperature Impact: Thermal expansion increases torque at elevated temperatures.
• Safety Factor: Actuator output torque should be at least 1.3 – 1.5 times the maximum measured valve torque.

8. Typical Applications

• Refineries: Fluid catalytic cracking (FCC) units, coker units, high‑temperature hydrocarbon service.
• Power Plants: Boiler feedwater, main steam systems.
• Thermal Oil Systems: High‑temperature heat transfer fluid circuits.
• Chemical Processing: Corrosive fluids at elevated temperatures, slurry handling.
• Coal Chemical: Black water, ash water, catalyst lines.
