Self-operated Differential Pressure Control Valve
-
- Commodity name: Self-operated Differential Pressure Control Valve
This product is a self‑acting control valve designed for open and closed water‑circulation systems, such as hot‑water heating systems and chilled‑water air‑conditioning systems. Its function is to maintain a constant differential pressure in the controlled loop, even when subjected to external disturbances (such as pressure fluctuations in the network) or internal disturbances (such as changes in internal resistance). It is particularly suited for differential‑pressure control in two‑pipe heating systems, helping to ensure system stability, reduce noise, balance hydraulic resistance, and mitigate thermal‑network and hydraulic imbalances. Whether the network pressure fluctuates or the internal resistance of the controlled loop varies, the ZYC‑type self‑acting differential‑pressure control valve can consistently maintain a stable differential pressure across the controlled loop.
