Shape Memory Alloy Boiler Flow Switch
Our shape memory alloy based switches are specially designed to automatically adjust the water flow according to incoming water temperature. They maintain a stable water flow even as water pressure changes. Based on specific water flow rate, these switches automatically output the corresponding signals to the controller for flow control.
