Features of D71X handle dual butterfly valve:

 1.  The disc plate adopts spherical machining method, plate flatness error is small, the valve opening and closing low torque, torque value good consistency, can be controlled within the scope of the standard torque value plus or minus 5, very suitable for mass assembly electric pneumatic device.

2. The valve seat sealing surface seal size is according to GB, ISO, AMST, JIS standard determination of the spot welding flange diameter maximum size, which is the valve and pipeline connection does not have special requirements, all can use flat welding flange, versatility, so as to thoroughly solve the center line of soft sealing butterfly valve flange connection type and diameter is demanding.

3. The plate and valve shaft are connected by a small, semi-axial and small modular spline structure, and the upper valve shaft is stronger than the non-pin valve shaft.The upper valve shaft seal is made of rubber sealing ring and nylon support sleeve structure. The lower shaft seal adopts the structure of two O - type rubber ring and solid seal grease. The medium will not leak from the valve shaft.

4. The valve flange holes covers standard, and high precision positioning hole, the other seat and body sulfide, control requirements for the seat compression deformation is not high, thus not demanding for installation personnel quality, quick operation, convenient installation of high efficiency.

The D71X handle is installed in the diameter of the pipe. Cylindrical channels in butterfly valve body, disc disc around the axis of rotation, rotation Angle for 0 ° and 90 °, and between the rotation to 90 °, the valve is fully open.
