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.

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.

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
