Once a control valve chokes, lowering downstream pressure stops adding flow — and the same conditions that cause choking can drive cavitation, flashing, noise, vibration, and erosion. This guide covers the sizing inputs, trim and actuator decisions, acceptance documents, and RFQ data buyers should confirm before ordering.
