4-011-04-0678 PRESSURE CONTROL VALVE G1/4 0.2-6 bar AVENTICS Pressure Regulator

When a pressure regulator on a Homag, Brandt or Ligmatech machine fails, the first sign is often inconsistent clamping pressure or erratic cycling. The 4-011-04-0678 AVENTICS regulator addresses this by maintaining stable air pressure between 0.2 and 6 bar. Without a working regulator, pneumatic actuators may not hold position, affecting hole quality and cycle times.

The AVENTICS pressure regulator with NL 2 configuration and G1/4 ports is a direct replacement for the Homag part number 4-011-04-0678 4011040678. It is used on Homag, Brandt and Ligmatech woodworking machinery. To confirm fit, locate the existing regulator and check for the NL 2 and G1/4 markings, and verify the pressure range matches 0.2-6 bar.

Mounting is straightforward: the regulator has G1/4 threaded ports for air line connection. Check that the mounting orientation allows access to the adjustment knob and that the air flow direction matches the arrow on the body. Correct installation ensures the regulator responds accurately to pressure changes, keeping downstream actuators within the 0.2-6 bar range.

Supply is as a single spare part; no special packaging or customisation is specified. When enquiring, provide the machine model, the part number 4-011-04-0678 4011040678, and the NL 2 G1/4 configuration to confirm compatibility. Also state the required pressure range 0.2-6 bar if your application differs.

What the specification fixes, and what it leaves to the machine:

• Pressure regulation range — Regulates air pressure from 0.2 to 6 bar, covering common pneumatic requirements on Homag, Brandt and Ligmatech machines.
• Port size and type — G1/4 threaded ports connect directly to standard pneumatic fittings, simplifying replacement on existing air lines.
• Mounting configuration — NL 2 configuration matches the original Homag part, ensuring drop-in fit without adapter modifications.
• Machine compatibility — Designed for Homag, Brandt and Ligmatech woodworking machinery, including CNC drilling and boring centres.
• Adjustment access — The pressure setting is adjustable within the 0.2-6 bar range, allowing tuning to specific actuator requirements.
• Wear points — The diaphragm and valve seat are typical wear points; replace the regulator when pressure cannot be held within 0.2-6 bar.
• Installation direction — Observe the flow arrow on the regulator body; incorrect orientation can cause erratic pressure regulation.
• Part number identification — Homag part number 4-011-04-0678 4011040678 is marked for positive identification during ordering and installation.
• Air line connection — G1/4 ports accept standard push-in or threaded fittings, reducing downtime during replacement.
• Pressure gauge port — Some configurations include a gauge port; check the existing unit for a pressure gauge connection point.
• Use — built for workshop gluing, on a bench beside the press or assembly table.

What changes on the shop floor once the unit is in place:

• Maintains consistent clamping pressure. Stable pressure between 0.2 and 6 bar keeps pneumatic clamps and actuators holding firmly, reducing variation in hole position and surface finish.
• Direct replacement for Homag part. The NL 2 G1/4 configuration matches the original, so no adapters or modifications are needed, cutting installation time and avoiding leaks.
• Compatible with multiple machine brands. Fits Homag, Brandt and Ligmatech equipment, allowing one spare part to serve several machines in a mixed-brand shop.
• Adjustable pressure range. The 0.2-6 bar range covers many pneumatic circuits, so the same regulator can be used across different stations with simple adjustment.
• Reduces troubleshooting time. When pressure issues arise, replacing the regulator with a known-good unit quickly isolates the fault and restores production.
• Simple installation with standard ports. G1/4 ports accept common fittings, so replacement can be done with basic tools during a scheduled maintenance window.
• Clear part number for reordering. The 4-011-04-0678 4011040678 number on the part simplifies reordering and ensures you receive the correct component.
• It replaces a manual step. A brush, a pot and a bench are all the unit needs; the glue is metered by the roller instead of by hand.
