1. Self-powered without external energy: The valve operates entirely on the pressure differential of the controlled system's medium, eliminating the need for external power, gas, or complex control circuits. This achieves energy-free automated operation with high system reliability and low initial investment and maintenance costs.
2. Precise preset and automatic pressure stabilization: Set and lock the target control value (flow rate or pressure differential) precisely using the adjustment handwheel on the valve top or a dedicated tool. Once set, the valve automatically maintains this parameter within the preset operating range, ensuring rapid response and high accuracy.
3. Extensive operational scope and excellent adaptability: The valve design features a wide adjustable ratio and suitable pressure differential range, capable of meeting dynamic variation requirements under different seasons and operating conditions, ensuring effective performance under all circumstances.
4. Integrated measurement and shut-off function: Most valve models feature standard measurement connectors on the valve body, enabling seamless connection with smart instruments for non-intrusive parameter monitoring, thereby simplifying debugging and diagnostics. Additionally, the valves provide reliable shut-off sealing performance, making them suitable as isolation valves in their respective circuits.
5. Energy efficiency and simplified commissioning: By automatically limiting and stabilizing flow or pressure differentials in each loop, the system significantly reduces the pump's ineffective head and overall energy consumption. Its "post-set automatic operation" feature also greatly reduces the workload for initial system adjustment and subsequent maintenance.
