What Is An Air Tank Check Valve?

Air tank Check Valve

Air tank Check Valve

An air receiver tank is fitted with a check valve that prevents air from escaping into the inlet line when the compressor stops.

Check valves are essential devices that prohibit reversal flows, preventing harm and maintaining efficiency.

The Tank Check Valve: How Does It Work?

Air tank Check Valve

Air tank Check Valve

The compressor motor starts when the pressure switch relay closes, and the compressor parts work correctly. 

Simultaneously, the compressor pressure switch (typically a toggle switch, but not always) closes the unloader valve. 

Air is now being pushed into the air tank by the air compressor.

None of it can pass through the unloader valve and down the line.

As a result, the tank check valve is open, allowing uncompressed air to enter the tank.

The pressure switch opens, the motor stops, the unloader valve opens, and the tank check valve closes, repeating the cycle.

Why Use A Check Valve?

Air tank Check Valve

Air tank Check Valve

Check valves permit the only one-way flow of compressed air through them—one of the numerous reasons why check valves are utilized in air compressors.

Depending on the kind, size, and manufacturer, a single compressor may include up to five check valves. 

Additionally, these check valves can prevent compressed air from being returned to the compressor via the pipe leading to the storage tank.

A check valve’s primary function is to prevent the system from backflowing.

Where Is The Tank Check Valve Located?

A tank check valve is normally located in the fitting where the pump head line enters the tank. 

The port bottom right with the ferrule and nut usually connects the pump head line. 

The little port pointing directly up is typically the line from the tank check valve to the compressor’s unloader valve. 

It can be challenging to locate this air compressor component; if you need assistance, please visit our support page.

Does A Check Valve Increase The Pressure?

The control valve can be used to increase the pressure of air entering the check valve gradually.

When flow is detected via the check valve, the valve’s cracking pressure will equal the pressure gauge measurement.
