Description
The DV-5005 screw valve is designed to dispense medium to highly viscous materials. The valve uses a removable screw conveyor to dispense two-component materials as well as materials that are abrasive, such as solder pastes, filled materials, and SMD adhesives. Three screws with different pitches are supplied with the valve. The VC1140 controller is used to control the valve control unit. The plastic screw can be replaced quickly, which greatly simplifies valve cleaning.

 

Functionality
The screw valve dispenses the material by means of a rotary screw conveyor from pre-filled syringes or cartridges which are under air pressure to transfer the material to the valve. The rotary screw pushes the material into the dosing needle. The amount of feed material depends on the pitch of the screw and its speed of rotation. The worm is powered by a 24 V DC motor with a power consumption of 22 mA at idle and 110 mA at start. The VC1140 can be programmed to not only dispense material, but also reverse the rotation of the screw, causing the material to return to the valve.

 

Features
* Replaceable material path - no cleaning required
* The feed screw can be replaced in a few seconds
* Choice of 3 feed screw pitches 6, 8, 16 turns / "
* Ideal for filler and abrasive materials
* Also suitable for UV sensitive materials
* The dose size is not affected by the change in viscosity e.g. from temperature
* Feedback control of the motor using an encoder (surcharge)
