Control Valve Selection : Flow Chart


Control valves are used throughout the process to control pressure, level, temperature, or flow. All control valves have variable opening or orifice. For a given pressure drop across the valve, the larger the orifice the greater the flow through the valve.

Type Selection : Globe valve, Double P-port shall normally be considered as the first choice. Control valves type and sizing selection process is shown on “Flow Chart For Valve Selection” below
