The adaptability of the butterfly valve on aggregate is best, but the larger cross-sectional area suitable for reversing swing, low and medium grade concrete pump, suitable for basic construction; S type pendulum valve during pumping pressure loss, concrete flow smoothly, but restricted by the diameter of the pipe, the aggregate demand is higher, suitable for in the distance, and the high-pressure pump, is suitable for the high quality of the concrete high-rise buildings and high lift transportation; performance between the S and the valve gate valve, widely used in medium pressure pump.
