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 materials and popular sizes, the DG/5FV is
ready to tackle most applications. Not only does the DG/5FV pro-
vide degassing, it is packed with features that increase safety, en-
hance performance and generally improves the convenience of op-
eration.
FEATURES
De-Gas – Bypass gasses and fluid during normal pump opera-
tion. Allows for the constant removal of gases that would other-
wise “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 an-
other 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.

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 posi-
tions.
The DG/5FV is compatible with most PULSAtron pumps.
Connected to the existing discharge valve the GG/5FV is
capable 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.
ITS = Integrated Tank System
The ITS System is a completely integrated tank system constructed of high
density UV resistant polyethylene (PE) with a 15 gallon capacity. This tank
system is translucent with 5 gallon increments and the tank's low level indica-
tor allows visual monitoring of chemicals without opening the tank. The tight
fitting child-proof lid keeps the chemical free of contaminants and protects the
surrounding area from chemical fumes.
The ITS System also allows for easy access to the liquid end and control
panel of the mounted pump.
A system consists of a chemical tank with lid and bulkhead fittings; a liquid
level indicator float assembly; and feeder mounting hardware.
ITS Tank not available on LM, LP, LT, and LE: H4, H5, H6,
H7, J7, H8, K7 models) If you require a different type or size
tank, please refer to our accessory price book.
