AVENTICS Pressure Regulator 4011040678 PRESSURE CONTROL VALVE NL 2 G1/4 0.2-6

Air pressure drifting on a Homag, Brandt or Ligmatech machine? The 4-011-04-0678 Aventics pressure regulator, also written 4011040678, is the pressure control valve that holds the circuit at the value it was set to. Regulated range 0.2 to 6 bar. Configuration NL 2, port thread G1/4, both read straight off the part name. 2 number formats, 1 valve, 3 machine builders covered.

Three things go wrong in a shop that runs Homag, Brandt or Ligmatech machines when a regulator tires. The set pressure creeps, so the same board is clamped differently from one shift to the next. The number on the old valve is written in a format the parts list does not use. And the machine stands while a small air-line part is chased through a supplier.

The 4-011-04-0678 Aventics pressure regulator, also written 4011040678, is the pressure control valve that holds the air of a woodworking machine at the value it was set to. Its configuration is NL 2 G1/4: NL 2 is the configuration code carried in the part name, and G1/4 is the port thread, so the port size is known before the old valve comes off the panel.

It regulates air pressure over 0.2 to 6 bar, the working range quoted for this valve, and that is the number to compare with the machine's gauge: a circuit outside 0.2–6 bar is not this regulator's job. It is listed for Homag, Brandt and Ligmatech machines, so 3 builders sit on 1 part number.

Both formats, 4-011-04-0678 and 4011040678, name the one part, so whichever is legible on the old body is enough to order. Price is quoted against the enquiry, and shipping runs by air, by sea or by express.

What a buyer checks on this valve before the order goes out:

• Two part-number formats — 4-011-04-0678 and 4011040678 are the same regulator, so either format on the old body is enough to order.
• Port thread in the name — G1/4 is written into the configuration, which fixes the port size before the valve is removed.
• Pressure band 0.2–6 bar — The regulated range runs from 0.2 up to 6 bar, the band quoted for this valve.
• NL 2 configuration — NL 2 is the configuration code in the part name and is quoted in full on the order.
• Three machine builders, one SKU — Homag, Brandt and Ligmatech — 3 brands covered by 1 part number.
• Listed as a Homag spare — It is carried as a spare for Homag woodworking machines, replacing the valve on a circuit that already exists.
• Order by the number on the part — No measuring and no matching by eye: read 4011040678 or 4-011-04-0678 and order that number.
• Pressure control valve type — The part is a pressure control valve, the type stated for 4-011-04-0678, so the function on the panel is unambiguous.
• Air, sea or express — 3 shipping routes, chosen per order so one valve can travel express.
• Quoted per enquiry — The price is given against the quantity and destination on the enquiry.

A part this small gets bought one of two ways: guess from the shelf, or lose a shift to it. This valve removes the guessing.

• One shelf slot instead of three. 3 machine builders — Homag, Brandt and Ligmatech — sit on 1 part number, so the store carries 1 valve line.
• Order from the worn part. 4-011-04-0678 and 4011040678 both resolve to this valve, so a half-legible number still brings the right part.
• The port size is settled early. G1/4 sits in the configuration, so the thread is confirmed before anyone climbs into the machine.
• Set the pressure once. Working across 0.2–6 bar, the valve holds the circuit where it was set, so clamp force stays put between shifts.
• Written the way the parts list writes it. It is quoted as a pressure control valve for 4-011-04-0678, the wording the machine's own list uses.
• One email, not a project. Price is quoted against the enquiry, so the answer comes back with a number instead of a catalogue request.
• Express when a line is down. 3 routes — air, sea, express — mean an urgent valve and a store refill need not travel the same way.
• No re-plumbing. It is sold as a spare for an existing machine, so the valve is what gets changed, not the circuit around it.

Order 4-011-04-0678 or 4011040678 — they are the same valve. One is the number written with separators, the other is the same digits run together, and both are listed against this part.

It is the configuration plus the port thread. NL 2 is the configuration code carried in the part name, and G1/4 is the thread on the ports, which is why the size can be read off the number instead of measured.

0.2 to 6 bar. That is the range quoted for this valve, so it suits a circuit working inside that band and is the wrong part for one running outside it.

Yes, if that machine's parts list quotes 4-011-04-0678. The valve is listed for Homag, Brandt and Ligmatech machines together, so the number on the machine, not the badge on the panel, decides it.

Both names describe this part. It is sold as an Aventics pressure regulator with 4-011-04-0678, and the type stated for that number is pressure control valve.

No. It is supplied as a single spare valve for an existing machine, so the part that is changed is the regulator, ordered by its own number.

Send the enquiry. The price is quoted against the quantity and destination, so the number that comes back matches the order being placed.

By air, by sea or by express. The route is picked per order, so 1 valve can go express while a store refill travels by sea.
