Theory of Operation
The SV200 uses a servo driven motor to rotate an auger inside the luer adapter of
the valve to provide a form of positive displacement control over fluid flow. Typical
applications include applying consistent bead patterns and dots of fluid where a high
degree of accuracy is required. With the quick release function of this valve, the motor
and auger assembly can be quickly removed from the luer adapter to clean the wetted
section. This valve is typically supplied with an SVC100 controller which is used to
program auger speed, dispense time, reverse time, and air pressure.
The SV200 has a divorced design comprising of two major sections. These include:
1) Servo Motor Drive (upper section)
2) Fluid Section (Red anodized aluminum and stainless steel)
The upper section is a servo drive motor used to accurately control the speed of
the auger screw and time that it rotates in the forward and reverse direction. The SCV100
controller has a digital display to select and program all parameters that will determine
fluid flow rate, shot size, and suck back.
The fluid section uses an aluminum retainer to house a stainless steel luer adapter
which acts as the fluid chamber. A screw type auger fits tightly inside to feed fluid
through to the dispense tip. The auger is connected directly to the servo motor and the rate
at which it is turned inside the luer adapter will determine fluid flow rate and dispense
volume. With little wear between the luer adapter and auger, this valve was originally
designed to dispense filled and abrasive pastes and fluids.
Wetted parts on the SV200 include:
- 304 stainless steel
- Aluminum, Red Anodized
- Viton, standard
