shouldself-actuated regulatorIt is a new type of regulating valve. Compared to manual regulating valves, its advantage is the ability to automatically adjust; Compared to electric control valves, its advantage is that it does not require external power. Practical application has proven that in closed water circulation systems such as hot water heating systems and air conditioning chilled water systems, the correct use of this valve can easily achieve flow distribution in the system; Can achieve dynamic balance of the system; It can greatly simplify the debugging work of the system; Can stabilize the working state of the pump, etc.
