Dynamic Balance Electric Control Valve

A valve that integrates pressure difference self balancing and electric regulation functions, automatically offsets pressure fluctuations in the pipeline network through a built-in stabilizing mechanism, ensuring precise flow control (error ≤ 5%). Suitable for variable flow systems such as HVAC and chemical engineering, it has the advantages of energy saving (reducing consumption by 6-20%), anti-interference, and fast response (≤ 10 seconds), simplifying installation and improving system stability.
