Order now the Kuhnke 68.023.60.41 — Atlantechdrives provides you with this high-flow pneumatic directional control solenoid valve from the Kuhnke 68 series, engineered for demanding industrial automation applications requiring robust, repeatable directional air control at high flow rates.
What Is the Kuhnke 68.023.60.41?
The 68.023.60.41 is a solenoid valve manufactured by Kuhnke (Kendrion), belonging to the 68 series — the higher-flow tier of the Kuhnke pneumatic directional valve portfolio. Decoding the part number: 68 identifies the valve body series, characterised by a larger body envelope and significantly higher Kv flow coefficients compared to the compact 41 and 46 series; 023 specifies the spool function or internal configuration code within the 68 series matrix — defining the number of ports, switching positions, and mid-position function (e.g. 5/2-way monostable, 5/3-way closed centre, or equivalent); 60 denotes a further configuration parameter such as port size, manifold interface variant, or pressure class; and 41 specifies the coil voltage — in Kuhnke nomenclature, 41 commonly corresponds to 24VDC, the dominant control voltage in industrial PLC architectures. Together these identifiers define a fully specified, high-flow directional valve configuration for direct integration into 24VDC-controlled pneumatic systems. The Kuhnke 68 series is a well-established platform in European industrial machinery, widely used in press, clamping, and large-actuator applications where sub-compact valve flow capacity is insufficient.

Compatibility and Applications
The Kuhnke 68.023.60.41 is the correct direct replacement for any Kuhnke 68 series installation specifying the .023.60.41 configuration. Its elevated flow capacity makes it the preferred choice for: Large-bore pneumatic cylinders with bore diameters above 63mm, where compact series valves create flow restrictions that limit cylinder speed and increase cycle time. Pneumatic presses and power clamps in automotive body assembly and metal forming, where fast fill and exhaust of large actuator volumes is critical. Centralised manifold distribution acting as a master flow control valve feeding multiple downstream circuits. Blow moulding and stretch-blow machines requiring high-flow air distribution for rapid mould pressurisation. Heavy industrial and off-highway equipment where large actuator displacements demand high-flow directional control.
Installation Advice
Before installing the Kuhnke 68.023.60.41, verify that the sub-base or manifold is specifically designed for the Kuhnke 68 series port pattern — the 68 series body is not interchangeable with 41 or 46 series manifolds. Confirm port orientation and flow direction markings on the valve body before connecting air lines; incorrect port assignment on a 5-port valve is a common commissioning error. Torque all sub-base fixing screws evenly to the Kuhnke-specified value to ensure uniform sealing of the valve-to-manifold interface O-rings — uneven torque is a leading cause of slow pneumatic leaks at the manifold face. For the 24VDC coil, wire the DIN connector with correct polarity and fit a flyback suppression diode across the coil drive output on the PLC or control card; without suppression, inductive spikes from coil switching will degrade solid-state outputs over time. After installation, perform a full functional test at minimum and maximum operating pressure before returning to production, verifying all ports and exhaust functions operate correctly per the .023 spool function specification.
Frequently Asked Questions
Q: How do I confirm whether the .023 configuration is a 5/2-way or 5/3-way function before ordering?
A: The .023 internal code maps to a specific spool function in the Kuhnke 68 series configuration matrix. Contact Atlantechdrives with the part number and we will confirm the exact spool function from Kuhnke documentation. Alternatively, on an installed valve, the number of solenoid coils visible on the valve body is a reliable indicator: one coil = 5/2-way monostable; two coils = 5/2-way bistable or 5/3-way. Never assume function from coil count alone — always verify against the datasheet for safety-critical circuits.
Q: Can the 68.023.60.41 be retrofitted to an existing installation using a different Kuhnke 68 variant with the same port size?
A: Physical fitment on a compatible 68 series sub-base is possible if the port size (.60 designation) matches. However, spool function must also match exactly — substituting a different function code (e.g. replacing a 5/3 closed-centre with a 5/3 pressure-centre) will change the fail-safe behaviour of the actuator circuit and may create unsafe conditions. Always confirm both port size and spool function before substitution.
Q: What is the minimum recommended upstream filtration for the Kuhnke 68.023.60.41?
A: Kuhnke recommends filtered compressed air with a maximum particle size of 40 microns and a pressure dew point at least 10°C below the minimum ambient temperature of the installation. For the 68 series in high-cycle service, a 5-micron coalescing filter-regulator upstream of the valve manifold is strongly recommended to protect spool seals and extend service life.
