A complete pressure control assembly for ProBlue melters, not just a single component swap.

The 1028307 is the pneumatic panel/pressure control assembly used in Nordson ProBlue series adhesive melters. It regulates and controls the air supply that drives the melter’s pump and includes the 24VDC solenoid valve responsible for pneumatic actuation within that panel. When a ProBlue melter starts showing erratic pump pressure or inconsistent adhesive output, the pressure control panel, not just the valve inside it, is often the root of the problem.

Key Specifications

• Voltage: 24VDC
• Operating pressure range: 0 100 PSI (0 7 bar, 0 700 kPa)
• Function: Regulates air supply and pneumatic actuation for the melter pump
• Compatible equipment: Nordson ProBlue series adhesive melters

Why Choose This Assembly

• Complete panel replacement addresses the pressure control system as a whole, not just an isolated valve
• Direct-fit for Nordson* ProBlue melters installs in place of the OEM assembly without modification
• Restores consistent pump pressure corrects the root cause of erratic adhesive flow tied to air supply regulation
• Simplifies servicing one assembly to install instead of diagnosing and replacing individual pneumatic components separately

Common Applications

• Preventive maintenance on Nordson* ProBlue melters
• Repair when pump pressure becomes inconsistent or adhesive flow becomes erratic
• Full pneumatic panel replacement during scheduled melter servicing

Who It’s For

Maintenance teams running Nordson* ProBlue melters who are troubleshooting inconsistent pump pressure or adhesive flow and need to replace the pressure control assembly at the source, rather than chasing a single valve.
