Australian Valve is a leading Check Valve Supplier in Australia. A check valve is a particular kind of valve that is intended to only permit one direction of fluid or gas flow while preventing backflow in the opposite direction. It is also referred to as a one-way valve or a non-return valve.In order to allow fluid or gas to flow in one direction while preventing backflow in the other direction, check valves typically consist of a valve body with an inlet and an outlet and a moving mechanism. Depending on how the valve is built, the moving element may be a ball, a disc, or a flapper.The check valve's movable mechanism is pushed open to allow fluid or gas to pass through it when fluid or gas is flowing through it in the proper direction. The moving mechanism is pulled shut by the pressure of the fluid or gas when there is backflow in the opposite direction, preventing backflow from happening.

Australian Valve is a major Check Valve Supplier in Australia, supplying to Queensland, Western Australia and Melbourne.
The main function of a check valve is to ensure that fluid or gas flows in one direction only, which is important in many different types of systems. For example, in a piping system, a check valve can prevent backflow of fluid or gas, which can cause damage to equipment or contamination of the system. In a pump system, a check valve can prevent backflow of fluid, which can cause the pump to lose prime.

Advantages:
1.Prevents backflow: The main advantage of check valves is that they prevent backflow or reverse flow of fluids, which can cause damage to pumps, pipes, and other equipment. By ensuring that fluid flows in one direction only, check valves protect the system from damage and prolong the life of the equipment.
2.Saves energy: Check valves help to save energy by reducing the load on pumps and other equipment. By preventing backflow, they ensure that the system operates more efficiently, which reduces energy consumption and costs.
3.Reduces noise: Check valves help to reduce noise in the system by preventing water hammer or other forms of pressure surges that can cause noise and vibration.
