520 = DG/5FV Five Function
Valve with De-Gas
With the DG/5FV you don’t have to give up the accuracy
and control of a solenoid metering pump in order to
pump gaseous solutions. Available in a variety of materi-
als and popular sizes, the DG/5FV is ready to tackle
most applications. Not only does the DG/5FV provide
degassing, it is packed with features that increase safety,
enhance performance and generally improves the con-
venience of operation.
FEATURES
 De-Gas – Bypass gasses and fluid during normal
pump operation. Allows for the constant removal of
gases that would otherwise “air bind” the pump.
 Back Pressure – Maintains output reproducibility and
allows metering into atmospheric discharge.
 Anti-Siphon – Prevents siphoning through the pump
when point of injection is lower than the pump or into
the suction line of another pump. Rated at total vacuum.
 Air Bleed – Used during priming to manually remove air from the pump head.
 Discharge Drain – Depressurize pump discharge line without loosening tubing or fittings. Protects the operator
from chemical exposure.
SPECIFICATIONS

Note: Degas/bypass volume is adjustable, typically 1-10% of pump output.
Connections: ¼” (0.635 cm) Male NPT
½” (1.27 cm) OD tubing
3/8” (0.95 cm) OD tubing
All ports (input, output & bypass) on the selected valve will be the same.
OPERATION
The functions are selected by setting two dual position selector knobs. The label on the back panel of the DG/5FV
identifies each function with selector knob positions.
The DG/5FV is compatible with most PULSAtron pumps. Connected to the existing discharge valve the GG/5FV is ca-
pable of handling a large output flow as well as viscous liquids. A return port located on the side body provides flow of
chemical back to the solution tank when in the degas, air bleed or drain discharge mode.
