Globe Valve vs Control Valve - When Do You Need a Dedicated Control Valve?
Globe valve vs control valve: when is a manual globe valve sufficient and when do you need an automated control valve? Cv, rangeability, positioner and trim selection explained.
[object Object] vs [object Object]: which should you choose?
Use a manual globe valve for utility services, bypasses, and set-and-leave throttling where process dynamics do not require automatic correction. Use a control valve wherever a PID loop (DCS or standalone controller) must automatically maintain a setpoint - temperature, pressure, flow, or level.
Overview
A manual globe valve provides proportional flow control through handwheel adjustment. Actuated globe valves with electric or pneumatic actuators can automate the control function, though without the precision of a dedicated control valve with positioner.
DN15–DN300, Class 150–2500, various materials
A control valve is a purpose-engineered globe (or rotary) valve with precisely selected trim, characterised flow coefficient (Cv), rangeability, and pneumatic/electric actuator with positioner. It responds to a 4–20 mA or digital signal to precisely maintain setpoint in closed-loop PID control.

Pros & Cons
Globe Valve (Manual / Actuated)
Control Valve
Globe Valve (Manual / Actuated) vs Control Valve - Specification Comparison
| Parameter | Globe Valve (Manual / Actuated) | Control Valve |
|---|---|---|
| Control Type | Manual or open-loop actuated | Closed-loop PID (4–20 mA signal) |
| Rangeability | ~10:1 | 50:1 to 100:1 |
| Cv Selection | Standard Cv - not process-sized | Engineered Cv from process sizing calculation |
| Flow Characteristic | Inherent only - not characterised | Equal percentage, linear, or custom plug trim |
| Positioner | Not standard | Standard - ensures position accuracy |
| Response to Process | Manual intervention required | Automatic - responds to setpoint deviation |
| Fail-Safe | Stays in last position | Fail-open or fail-closed on air/signal loss |
| Cost | Low | 3–10× higher (trim, actuator, positioner) |
| Maintenance | Low | Higher - trim, packing, positioner calibration |
| Standards | BS 1873, API 623 | ISA 75.01, IEC 60534, ANSI/FCI 70-2 |

Decision Guide
Use a manual globe valve for utility services, bypasses, and set-and-leave throttling where process dynamics do not require automatic correction. Use a control valve wherever a PID loop (DCS or standalone controller) must automatically maintain a setpoint - temperature, pressure, flow, or level. If the process cannot tolerate deviation from setpoint during transients, a control valve is mandatory.
