Applications


Ball Valve Venting Internal and External Venting
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

Steam Valve Applications
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
