Pressure Discharge Valve for Nordson® ProBlue Pumps

Pressure Discharge Valve for Nordson® ProBlue Pumps
The ProBlue Nordson® Melter manifolds are equipped with a pressure discharge valve.
When the pump is switched off at the control panel, air is removed from the top of the valve forcing it to open. When the valve opens, pressurized material within the pump and manifold bypasses through the pressure discharge valve and is returned to the tank.
Symptom for replacement:
If adhesive is returning to tank through the return port located behind the tank screen
