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!

product advantages

true volumetric conveying endless piston principle @ technology

wide applicable viscosity range applicable to various viscosity media

easy to clean modular design, easy to use and clean

precise volume control the output flow is directly proportional to the speed and is not affected by the changes of medium viscosity, pressure and temperature

high precision conveying accurate metering, flow error less than 1%

high repetition accuracy conveying repetition accuracy above 99%

it can transport medium containing particles the maximum medium particles can reach 1 mm

high speed up to 3 times / s

versatility easy integration with automation system and simple control

no pulsation stable and stable output flow

stable output self sealing structure design

it can be sucked back no drip, no wire drawing
