1. JKA controller: a multifunctional controller designed specifically for softening and demineralization, easy to operate. 2. Pulse signal flow sensor: high measuring accuracy (up to ±4%), strong anti-interference ability. 3. All-plastic double-chamber diaphragm valve: with high flow rate and low pressure loss, it can be controlled by air and water, and is highly resistant to corrosion, making it suitable for use in demineralization systems. 4. The JKC flow control system can be used to achieve the online connection of multiple devices, enabling continuous water output from the equipment.
