D971X

D971X clamping type electric soft seal butterfly valve main advantages, simple structure, small volume light weight, low cost, pneumatic disc valve installed in the air, through two clamping type electric soft seal butterfly valve five solenoid valve control operation, but also adjustable flow medium. Fluid resistance is small, large diameter pneumatic disc valve fully open the effective flow area is larger, easy opening and closing fast, disc pull rotation Angle of 90 to complete opening and closing, due to the rotation axis disc plate hａnd medium force nearly equal, and the torque in the opposite direction, thus opening and closing torque is small, low pressure can achieve good sealing, disc valve sealing material is nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, which is suitable for soft hard cascading metal hard seal butterfly valves with metal sealing and elastic sealing advantages, under the condition of low temperature has good sealing performance.
