YDF-2F, 20F Type Differential Pressure & Flow Control Valve
This valve performs the two control functions of restricting flow and maintaining a differential
pressure of supply and return lines. It can be installed in a supply line or return line according
to its purpose of use.
Features
• High-performing differential pressure flow control valve that is installed in a supply or return line of a load
device to control the differential pressure and flow comprehensively.
• In addition to differential pressure control, it offers a wide flow control range, from small to large flows,
thanks to an embedded equal % cone for flow control.
• The diaphragm is separated from the body and thus is not affected by temperature. Since it is a perfect
balance type, the set differential pressure does not change due to pressure fluctuations.
• Has a solid structure, and thus offers an outstanding level of durability.
• A diaphragm method enables to be installed horizontally or vertically.
• The opening percentage of the valve can be easily checked, thanks to the attached indicator.
• Leakage from packings can be visually checked, enabling easy identification of the appropriate time for repair.
