ApplicationYK series pressure controller functions to control pressure transmission power switch on/off based on the principle of instability jumping when the dish metal diaphragm is under uniform pressure load. It is mainly used for high or low pressure protection and controls on household, commercial and automotive air conditioning refrigerating systems, and can also be used to protect and control high or low pressure on air compressor, hydraulic machines, various equipment and tools.
