Brand Name: Hengsen
Model Number: DF/F-08DP
Place of Origin: China
Product introduction
SF-08DP series of valve is a combination of balancing valve and control valve. It is widely used to control temperature in heating system (such as Make-up Air Unit and Air Handling Unit). It control flow value and temperature in every circle. It is intellective management. Then save energy and reduce wastage.
Advantages
●Stability: Flow value is not influenced by pressure undulation. Flow value is not influenced by each other.
●Save energy: It can save more 6%-20% energy than traditional system.
●High efficiency: Less testing time and effective system running.
●Comfort: It is more comfortable with small temperature adjustment tolerance.
Features
●Valve flow characteristic: Liner or equal percentage.
●Flow value tolerance:≤5%
●Ambient temperature: 0-150℃
Material and lifetime
●Valve body: Cast iron
●Inner parts: Brass, stainless steel
●Spring: Stainless steel
●Diaphragm: EPDM
●Lifetime: More than 10 years
Installation and maintenance
●When maintenance, make sure there is no pressure in the water system
