Self operated balancing valve

Self operated balancing valve is the most common and representative form of dynamic balancing valve, and its name directly reveals its core feature: relying on the pressure changes of the system's own medium as a power source to achieve automatic and constant flow. It is a fully automatic mechanical flow control device that does not require external power or pneumatic drive. Valves usually integrate differential pressure sensing diaphragms (or pistons), springs, and regulating valve cores. During system operation, when the pressure difference between the front and rear of the valve changes, the force sensed by the diaphragm will be compared with the set force of the spring, thereby driving the valve core to automatically adjust the opening: it will be closed when the pressure difference increases, and opened when the pressure difference decreases. This process continues dynamically and ultimately stabilizes the actual flow through the valve around the preset value. Kaiweixi Valve Group mainly produces self operated differential pressure balance valves, self operated flow balance valves, self operated temperature balance valves, and self operated balance valves with locks. Self operated balance valves are mainly used in variable flow systems for heating or air conditioning, and are installed at the inlet of end devices such as fan coil units and heat exchangers. Its core advantage lies in eliminating complex debugging, effectively solving the problem of system dynamic imbalance, ensuring efficient operation of each end at the designed flow rate, avoiding overheating or underheating, and being a key automation component for achieving system hydraulic balance, reducing energy consumption, and improving comfort.
