Australian Valve is the foremost Dual Plate check Valve Supplier Australia. A dual plate check valve, also known as a double-disc check valve or twin plate check valve, is a type of check valve designed to allow the unidirectional flow of fluids (liquids or gases) while preventing backflow. It is called dual plate because it consists of two spring-loaded plates or discs that are hinged in the center and positioned within the valve body. The presence of two plates or discs that open and close together in response to fluid flow. : Each plate is typically spring-loaded, which means that when there is no fluid flow or when the flow is in the reverse direction, the springs keep the plates closed, effectively sealing the valve. They have minimal pressure drop when in the open position, allowing for efficient flow through the valve. These valves can close quickly when the flow direction reverses, preventing backflow and water hammer effects. These have a compact and lightweight design, making them suitable for various applications where space is limited. These have minimal pressure drop when in the open position, allowing for efficient flow through the valve. These results in quiet and non-slam operation, making them suitable for applications where noise is a concern.
