Vacuum Breaker & Air Vent Valves – Protect Your System from Vacuum Collapse

At Solenoid Valve World, we supply high-quality vacuum breaker valves and automatic air vent valves designed to protect piping systems, tanks, and process equipment from vacuum formation and trapped air. These valves are essential for maintaining stable pressure, preventing flow interruptions, and avoiding structural damage in water, steam, and process systems.

What Is a Vacuum Breaker or Air Vent Valve?

A vacuum breaker valve automatically allows air to enter a system when internal pressure drops below atmospheric pressure, preventing vacuum conditions that could collapse tanks or deform piping.

An air vent valve, on the other hand, allows unwanted air to escape from the system—typically during filling or normal operation—ensuring smooth and efficient fluid flow.

Both are critical for:

Closed loop systems

Hot water systems

Steam lines

Irrigation networks

Chemical and process plants
