4-011-04-1920 Valve For Homag Woodworking Machine VUVG-L14-M52-MT-G18-1P3

When a short stroke cylinder on a Homag machine loses force or starts to stick, the result is inconsistent clamping, poor feed control, or a stop that will not hold position. The 4-035-01-0670 addresses that specific failure by replacing the worn cylinder with one that matches the original KHZ D63 HUB50 G1/4 KDU=7 specification.

This is a short stroke cylinder with a 63 mm diameter and a 50 mm stroke length. The air port is threaded G1/4. It fits Homag machines that use the KHZ D63 HUB50 G1/4 KDU=7 cylinder.

Before mounting, check that the G1/4 port matches your air line fitting and that the 50 mm stroke suits the mechanism it drives. The cylinder mounts in place of the original, using the same G1/4 connection. In use, the 63 mm diameter provides the clamping force for the application, and the 50 mm stroke gives the travel needed for the machine function.

Supply comes as the cylinder alone; no additional packing or customisation is stated. For an accurate quote, send the Homag number 4-035-01-0670, the full specification KHZ D63 HUB50 G1/4 KDU=7, and the quantity you need. A photo of the existing cylinder's markings helps confirm you receive the correct replacement.

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

• Direct replacement for worn cylinders — The 4-035-01-0670 replaces the original short stroke cylinder on Homag machines, restoring the 50 mm stroke and 63 mm diameter without modification.
• Bore size for clamping force — A 63 mm diameter gives the cylinder the bore area needed to produce clamping force for the machine's hold-down or feed mechanism.
• Stroke length for travel — The 50 mm stroke length provides the travel required by the mechanism, matching the HUB50 designation on the original cylinder.
• Air port thread — The G1/4 thread connects to standard pneumatic fittings, so you can reuse existing air line connections without adapters.
• Fitment check by Homag number — Confirm the Homag number 4-035-01-0670 on the old cylinder or in the machine manual before ordering to ensure a direct fit.
• KHZ series identification — The KHZ designation identifies the cylinder series, helping you match the replacement to the machine's original specification.
• KDU=7 specification — The KDU=7 marking on the cylinder indicates the original configuration, so you can verify the replacement matches the old unit.
• Mounting without modification — The cylinder mounts in place of the original using the same G1/4 port and 50 mm stroke, so no changes to the machine are needed.

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

• Restores original machine performance. By matching the 63 mm diameter and 50 mm stroke, the 4-035-01-0670 brings the cylinder's force and travel back to the original specification, so the machine runs as intended.
• Avoids guesswork on fitment. The Homag number 4-035-01-0670 and the KHZ D63 HUB50 G1/4 KDU=7 marking give you two clear references to check against the old part, reducing the risk of ordering the wrong cylinder.
• Keeps air line connections simple. The G1/4 thread means you can reuse existing pneumatic fittings and hose, so installation does not require new adapters or changes to the air supply layout.
• Cuts downtime from cylinder failure. A sticking or weak cylinder stops the machine; having the correct replacement 4-035-01-0670 on hand lets you swap it out and get back to production faster.
• Maintains clamping consistency. With the correct 63 mm bore and 50 mm stroke, the cylinder delivers consistent clamping force stroke after stroke, helping hold tolerances on machined parts.
• Matches the original specification. The KHZ D63 HUB50 G1/4 KDU=7 specification matches the original cylinder, so you are not fitting a modified part that could alter machine behaviour.
