Features Specifications Differential Pressure and Flow Dimension Application

Features

When the differential pressure of the system fuctuates, the valve cartridge automatically adjusts the opening of the variableflow channel to achieve constant flow in the controlled area
The precisely calibrated valve core ensures a constant error within 5%
Preset flow in factory, each size has multiple differential pressure ranges selectable
No on-site commissioning required, reduce labor cost
