What Is Brass Air Valve?

Brass Air Valve

Air valves are hydromechanical devices that automatically release or admit air during the filling, draining or operation of water and wastewater piping systems.

Why Is Brass Used For Air Valves?

Brass Air Valve

Brass is a blend of copper, zinc, and other metals. 

Unlike plastic valves, soft metal valves resist corrosion better than complex metal valves. 

Brass is also more heat resistant than plastic, making brass valves ideal for residential plumbing systems.

What Are The Different Types Of Air Valves?

An air valve is a device that allows for the discharge of air from a system.

These are three types of air valves that are installed in potable water supply systems.

➢ Air and Vacuum valves

Air and vacuum valves remove significant amounts of air from non-pressurized pipes and are used to fill lines. 

Air and vacuum valves allow substantial air to enter when lines are drained or when pressure lowers unexpectedly.

Air and Vacuum valves

➢ Automatic air release valves

Automatic air release valves continuously release small amounts of compressed air. 

Also known as a small orifice air valve and a pressure air valve.

Automatic Air Release Valves

➢ Combination air valves

Combination air valves combine the functions of air, vacuum, and automated valves. 

If the line is pressurized, they continually discharge small quantities of air.

What Are The Benefits Of Brass Air Valves?

Air valves allow air to enter or exit a pipeline without leaking water.

These are the benefits of a pipeline air valve:

• Reduce Hastened corrosion
• Reduces energy use and operating expenses
• Flow metering accuracy
• Reduces mains filling time, therefore increasing pump and pipeline efficiency
• Reduces water hammer
• Sudden air pocket shifts can cause enormous pressure spikes. A smaller pipeline decreases the risk of a surge.

Why Are Brass Air Valves Required In Water Applications?

Brass Air Valve

Air valves help release trapped air, ensuring smooth water flow in pipes and irrigation system operation. 

It occurs when the Air valve opens due to internal pressure in the water pipe.

What Are The Functions Of Brass Air Valves?

Air valves serve three primary purposes: 

• Water flow reversal

Valves can start and stop the water flow if the water system does not require a throttled flow.

• Throttling water flow

Throttling the flow is just lowering the water flow as needed. 

The valve’s principal function is to lower system pressure.

• Maintaining proper water flow

The valves do this crucial job. 

The system’s adequate operation requires adequate water flow. 

Valves open and close according to the flow of water. 

Thus, valves help avoid water backflow.

What Is The Tip For Installing Brass Air Valve?

Brass Air Valve

The optimal place to install them is at the pipeline’s apex. 

Many individuals install pipes underground, necessitating a separate vault for the valves.

It is also necessary to correctly size the connecting pipes. 

Stretched air valve pipes might generate water surges that require examination.

A maintenance shutoff valve in the air is required. 

Our recommendation is to use a riser pipe larger than the air valve creek. 

Once a year should test the ditch valve.

Repair or replace the air release component of a ditch valve that ejects air. 

Otherwise, you should check the air valve while running the pump to ensure it is not leaking air.
