This valve structure by GB12221 - length The provisions of the 1989 flange size according to JB/T79 - period The provisions of the 1994. The wafer butterfly valve has simple structure, large and small, light weight, only by a few parts. (5) can be based on user requirements is equipped with pneumatic, electric actuator, satisfied with remote sensing and program requirements. 。 Wafer butterfly butterfly plate installed on the diameter of the pipe direction. The wafer butterfly Industrial Valves structure unique place (1) three to unjust unique special preset no friction between the tightly closed surface drive, extended the valve use fixed number of year of survival. Cylindrical channels in butterfly valve body, disc disc around the axis of rotation, rotation character of 0 & amp; 度; - 90 & 度; Between, can have the effect of flow control, when the butterfly plate rotation to 90 & amp; 度; When the maximum opening Industrial Valves. 6. Change parts material can be suitable for use in a variety of media, the lining and can implement Marine valve and rotting ( Lining F46, GXPP, PO, etc. ) 。 (2) by the torque initiation elastic tightly closed. And only need to rotate for 90 & amp; 度; Can rapid opening and closing, simple operation, at the same time the valve have satisfactory curb the special nature of the fluid. (4) large and small, light weight, light operation, easy to install. (3) clever clever wedge default make valve has closed more and more tightly semi-automatic tightly closed function, tightly closed between surface have to repay, zero leakage. All landowners back-to-back structure diversification, clamp, flange, butt welding.
