SS304 Mini Air Release & Vacuum Relief Valve (Male Thread)

Prevent air-locks and pipeline implosions in compact systems with the Aomite Mini Air Release & Vacuum Relief Valve.

Engineered for small-scale sanitary pipelines, pump housings, and mini tanks, this highly compact, dual-function mechanical valve provides essential two-way protection. First, it acts as an air release valve (exhausting internal pressure when it exceeds the standard 1 Bar setpoint). Second, it automatically functions as a vacuum breaker (instantly opening to let ambient air in when the system drops to a vacuum of -0.9 Bar). Precision-machined from SS304 or SS316L stainless steel with resilient EPDM/FPM seals, it features standard male threads (such as 1/8" NPT/BSP) for quick, secure installation via its hexagonal wrench-friendly body. Max working temperature: 120°C.

How does a dual-function Air Release & Vacuum Valve work?

1. Air Release (Overpressure Protection)
When the pipeline is filling with liquid, or when gas accumulates at high points, the internal pressure rises. Once it exceeds the factory setpoint (e.g., 1 Bar), the internal mechanism lifts, exhausting the trapped air to prevent air-locks and pump cavitation.
2. Vacuum Release (Implosion Protection)
When a pipe is draining rapidly or a pump shuts down, it can create a dangerous vacuum that might collapse thin-walled pipes. When the pressure drops to -0.9 Bar, the valve automatically sucks ambient air into the system, neutralizing the vacuum.

Is this valve used for measuring water like a Water Meter?

No Measuring Function: This device is strictly a mechanical protection valve. It does not measure flow rate, volume, or act as a water meter in any capacity.
Application: It is designed to be installed at the highest points of fluid pipelines or on top of centrifugal pump housings to manage trapped air and vacuum conditions safely.
