Protect Your Side Channel Blower: How the 2BX Series Safety Valve Works

Why the 2BX Relief Valve Matters

Side channel blowers are used in all kinds of industries—wastewater aeration, pneumatic conveying, food machines, packaging, and more. While they are reliable, they’re also sensitive to pressure overload. That’s where the 2BX Series Safety Valve comes in. It acts like a simple but powerful “bodyguard” for your blower, protecting it from sudden surges or dangerous pressure levels.

Preventing Damage Before It Starts

Without a relief valve, a single pressure spike can lead to overheating, noise, deformation of components, or even total blower failure. The 2BX valve releases overload pressure before any of that can happen.

A Strong, All-Metal Design

The structure of the 2BX series is built for stability and long service life.

What It’s Made Of

The spindle, adjustment nut, and spring are made of durable steel.

The valve housing is made from lightweight aluminum alloy.

This combination gives the valve both strength and corrosion resistance while keeping it light and easy to install.

Reliable Performance You Can Trust

One of the biggest advantages is its 5% repeat-accuracy rating. This means the valve reacts consistently every time pressure reaches the set limit. No random opening, no delayed response—just stable protection.

How the 2BX Relief Valve Works

The valve is installed on the inlet or outlet of the side channel blower. It continuously watches the internal pressure and responds automatically.

1. It Opens Fast When Pressure Gets Too High

If working pressure rises above the blower’s rated limit, the valve opens in under 0.2 minutes.
This quick action releases the extra pressure and stops the blower from entering unsafe conditions.

2. It Closes Slowly to Avoid New Pressure Surges

Once the system pressure returns to a safe level, the valve closes gently and slowly.
This prevents a second pressure shock and keeps airflow stable.

3. Works in Both Pressure & Vacuum Conditions

The same valve can protect systems running with positive pressure or vacuum, making it a versatile choice for many industries.

Where You’ll See It in Action

The 2BX Series Safety Valve is widely used anywhere side channel blowers operate in variable or unstable pressure environments.

Common Applications

Wastewater treatment: prevents pressure spikes in aeration lines

Pneumatic conveying: protects against sudden blockages

Food and packaging equipment: keeps airflow smooth under fast-changing loads

General industrial air systems: improves reliability and reduces downtime

In all of these situations, the valve helps maintain stable pressure, protects expensive equipment, and avoids unexpected shutdowns.

Simple Device, Big Impact

What makes the 2BX relief valve valuable is not complexity but consistency.
It reacts fast, closes smoothly, handles pressure cycles reliably, and works in both positive and negative pressure systems. For anyone using a side channel blower, adding a 2BX safety valve is one of the easiest ways to extend blower life and prevent pressure-related failures.
