The Effect of Pressure Drops in Valve Selection and System Efficiency

Proper valve selection minimizes pressure losses, ensuring efficient operation in pipeline systems.

• Flow Coefficient (Cv): Determines the flow capacity of a valve. Engineers select valves with appropriate Cv values to prevent excessive energy losses.
• Turbulence and Pressure Recovery: Globe valves tend to have higher pressure drops due to flow path changes, while ball valves maintain better pressure recovery.
• Reducing Pressure Losses: Using full-bore designs and streamlined trim configurations helps optimize flow dynamics.
