ZLF (ZL47) -16 Self Operated Flow Control Valve

DN50-600
ZLF (ZL47) -16 Self Operated Flow Control Valve (Dynamic Flow Balance Valve) DN200Product IntroductionSelf operated flow control valve (also known as dynamic flow balance valve) relies on the pressure difference of the medium itself to achieve automatic constant flow, without the need for external power supply or instrument drive. When the pressure difference in the pipeline network fluctuates, the valve automatically adjusts the flow area to ensure that the branch flow is stable at the set value, solving the problems of hydraulic imbalance and uneven heating and cooling in the heating and central air conditioning circulation pipeline network. Suitable for central heating, building air conditioning, and industrial circulating water systems, achieving constant flow in each loop, ensuring stable hydraulic conditions in the pipeline network, and energy conservation and consumption reduction.Core Parameters• Model: ZLF-16/ZL47-16• Nominal diameter: DN200• Nominal pressure: PN16 (1.6MPa)Valve body material: QT450 ductile iron• Connection method: flange connectionApplicable media: hot water, cold water circulating water• Medium temperature: 0-120 ℃Minimum starting pressure difference: 0.02MPa• Coating: Internal and external epoxy resin electrostatic spraying• Adjustment method: pre-set flow rate, self operated automatic constantProduct advantages1. Self operated automatic constant current, no need for electricity or gas source, and the flow rate remains unchanged within the range of pressure fluctuations;2. After setting the flow rate, it automatically adjusts without the need for manual repeated debugging, ensuring long-term stability;3. The ductile iron valve body has high strength and resistance to water hammer. It is coated with epoxy for corrosion and rust prevention, meeting the requirements of water supply, drainage, and heating conditions;4. Reliable structure, built-in pressure sensing adjustment components, sensitive response, smooth adjustment without impact;5. The bidirectional flange standard is universal, easy to install, and mainly for horizontal pipeline installation;6. Effectively solve the problem of excessive near end flow and insufficient far end flow, reduce water pump energy consumption, and achieve significant energy-saving effects;7. It can lock the set flow rate to avoid arbitrary changes, suitable for centralized management of heat and property.
