ATO PVC diaphragm valve uses a flexible PTFE diaphragm that separates the valve's body from the flow path. This diaphragm is made of CPVC or UPVC which can withstand corrosive or acidic substances.
Tips: How does a diaphragm valve stop flow?
A diaphragm valve stops flow by using a flexible diaphragm, a membrane-like barrier, as the primary sealing element. When the valve is in the open position, the diaphragm is lifted, allowing fluid to pass through the valve. To stop the flow, the operator or actuator lowers the diaphragm, pressing it against the valve seat, creating a tight seal. This action effectively obstructs the flow path and prevents the passage of fluids or gases.
The diaphragm's flexibility and ability to conform to the seat surface make it an effective and reliable shut-off mechanism. Diaphragm valves are commonly used in applications where precise flow control and cleanliness are crucial, such as in the pharmaceutical, food and beverage, and water treatment industries. Their straightforward design and ease of maintenance make them a popular choice for various applications requiring flow isolation.
