D971J-10The valve body is lined with rubber and the valve plate is covered with rubber. It can be used to control the flow of water, steam, oil, gas, mud, corrosive media, liquid metal and radioactive fluid. Butterfly valve is a butterfly plate with the valve stem rotating together as the opening and closing parts to realize the opening, closing and adjustment of the valve. In recent years, the sealing performance of butterfly valve has been regarded as the main evaluation index in pipeline, which is favored by the market. In addition, butterfly valve has the advantages of small size, light weight and simple structure. Compared with the gate valve with the same parameters, the average weight is reduced by 30 ~ 50%. The opening and closing process can be realized by rotating the butterfly plate by 90 degrees. Moreover, due to the similar medium force on both sides of the rotating shaft, the torque is opposite, and the opening and closing torque is small.

D971J-10Temperature resistance and suitable medium of main sealing ring of double clip electric full lined rubber butterfly valve
Material code of sealing ring	Applicable temperature	Applicable media
NR	≤85℃	Water, air, acid and alkali
CR	≤85℃	Water, gas, acid and alkali
NBR	≤100℃	Water, oil
EPDM	≤120℃	Water, steam, general acid and alkali
FKM	≤150℃	Water, steam, strong acid and alkali

1. The design is novel, reasonable, unique in structure, light in weight and quick in opening and closing.
2. Small operating torque, convenient operation, labor saving and dexterous.
3. It can be installed in any position and easy to maintain.
4. The sealing element can be replaced, the sealing performance is reliable, and the two-way sealing is zero leakage.
5. The sealing material has the characteristics of aging resistance, weak corrosion resistance and long service life.
Note: for the corrosion resistance of rubber lined valve, refer to the corrosion resistance table of various chemical media of rubber lined valve.
