Variable Orifice Nozzle

Updated: 2026-08-05

Overview

A reducing air nozzle is a critical component in pneumatic systems, designed to modify airflow by altering the diameter of the air passage. It is widely used in industries such as manufacturing, automotive, and aerospace to ensure precise air pressure and flow control. The nozzle's adjustable design allows for versatility in applications, making it suitable for systems requiring variable airflow rates. Its robust construction ensures longevity even in high-pressure environments.

Structure and Working Principle

The reducing air nozzle typically consists of a tapered or stepped interior that narrows the airflow path, thereby increasing air velocity and controlling pressure. The design may include threaded ends for secure attachment to pneumatic lines. When air passes through the nozzle, the reduced diameter accelerates the airflow while maintaining or adjusting the pressure as needed. This principle is essential for applications requiring consistent and controlled air delivery.
