Applications

Ball Valve Venting – Internal and External Venting
The vent port evacuates trapped pressure from the system directly to atmosphere when the valve is closed. The ball contains a vent passage isolated from the ball orifice to prevent continuous leakage from the body vent port when the valve is open.

Ball Valves for Steam Service

DM4600 Series

  • Saturated Steam – when heated water reaches its boiling point
  • Wet Saturated Steam – a mixture of saturated steam with condensed water particles present
  • Dry Saturated Steam – saturated steam is free of water particles
  • Super Heated Steam – saturated steam passed through superheater, increasing temperature without increasing pressure
