Description

TECHNICAL DATA SHEET

Product: 2-Piece Metal Seated Floating Ball Valve
Size: 2 inch (DN50)
Pressure Class: Class 1500
Body Material: A105N (Normalized Carbon Steel)
End Connections: Flanged (ASME B16.5)

1. Basic Specifications

Parameter Value
Nominal Size 2″ (DN50)
Pressure Rating Class 1500 (PN250)
Body Construction 2-Piece
Ball Type Floating
End Connections Flanged – ASME B16.5 (RF or RTJ)
Temperature Range –29°C ~ +500°C (depending on hardfacing)
Suitable Media High-temperature steam, thermal oil, corrosive fluids, high-pressure gas/liquid
Fire Safe Design API 607 / ISO 10497

2. Main Features

  • Metal Seated: Ball coated with tungsten carbide or Stellite; seat hardfaced with Stellite alloy. Excellent wear, erosion, and high-temperature resistance.

  • 2-Piece Body: Compact construction, easy maintenance. Body joint secured with high-strength bolting.

  • Floating Ball: 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 high-pressure conditions.

  • A105N Body: Normalized carbon steel body provides improved toughness and grain structure, ideal for high-pressure and moderate high-temperature services.

High-Pressure Hydrostatic Test 1.5 × rated pressure (body), 1.1 × rated pressure (seat)

6. Operating Torque & Actuator Sizing Considerations

  • Seat Preload: Spring-loaded metal seats add initial breakaway torque.

  • High-Temperature Effects: Thermal expansion increases torque at elevated temperatures.

  • Safety Factor: Actuator output torque should be at least 1.2 to 1.5 times the maximum measured valve torque.

7. Typical Applications

  • Refinery fluid catalytic cracking (FCC) units

  • Power plant boiler feedwater and main steam systems

  • High-temperature thermal oil circuits

  • High-pressure natural gas transmission

  • Coal chemical industry – ash water & black water service
