Single / two component screw valve

Single / two component screw valve

The special product structure design makes the product medium conveying stable and without pulsation. At the same time, the product has the function of suction back, which completely avoids the phenomena of drip and wire drawing of medium conveying.

The product has the advantages of constant conveying flow, no pulsation and low shear, especially for conveying high viscosity, sensitive and granular media.

Therefore, preeflow is: a solution for a variety of complex applications!
