Valve Service Department for support. This department can be reached at PVA
headquarters via telephone or e-mail.
Again, thank you for your purchase, and we look forward to assisting you in the
future as you continue to improve your dispensing processes.
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

Valve Options
The SV200 valve is available with a different thread pitch on the stainless steel
auger for high, medium, and low flow applications. Different size syringe mount inserts
are also available to support various diameter syringe barrels. A 30cc syringe adapter
support bracket is standard with the valve and inserts can be added for additional support.

Safety
Due to material contents being under pressure eye protection is required for
operators. Refer to MSDS sheets on material being dispensed for other precautions.
Setup
Each SV200 auger valve requires an SVC100 controller for operation. A two pin
motor cable (23) is used to connect the controller and the valve to transfer the signal used
to rotate the auger. A second air output on the controller is used to supply air pressure to
the syringe of fluid only when the auger is spinning in the forward direction. Fluid is
typically supplied to the valve from a syringe mounted directly to the valve using the
disposable feed tube (20). PVA offers universal syringe air adapters that will connect the
syringe to the 5/32”od tube air output of the controller.
