Differential Pressure Control Valve

A differential pressure control valve (DPCV) is an automatic, self-operating regulating valve engineered to maintain a constant, pre-set differential pressure across a specific loop or sub-system regardless of flow rate fluctuations elsewhere in the network. Utilizing an internal diaphragm mechanism connected to impulse tubes on both the supply and return lines, the valve dynamically opens or closes to absorb excess pressure spikes and prevent hydraulic imbalance. Conforming to standards like EN 1349 and ASME B16.34, these self-actuating control valves are critical specifications in commercial HVAC hydronic distribution networks, district cooling loops, and industrial heat exchanger systems, allowing building utility engineers to optimize energy consumption and balance hydraulic pressure by importing certified differential pressure control valves directly from leading manufacturers in China via our advanced B2B commercial platform.
