Does the Vent plug without filter AKO1 require periodic inspection of the O-ring and check valve to ensure proper sealing and opening pressure?

Yes. The Vent plug without filter AKO1 should be inspected periodically. Although it is designed with an O-ring and a check valve to provide sealing and open at a defined pressure (0.15â0.3 bar) to vent oil turbulence while preventing contamination, routine checks help ensure continued reliable performance. Inspect the O-ring for signs of aging, hardening, cracking, swelling or deformation that could compromise the seal. Verify the check valve moves freely and reseats properly and that its opening pressure remains within the specified 0.15â0.3 bar range (or that it opens consistently under normal operating pressure changes). Also check the housing and cover for corrosion, contamination, or damage, and ensure the fiber washer (guarnital) is intact. Perform inspections more frequently in harsh environments, high-cycling systems, or where contamination risk is elevated. Replace components showing wear or damage to maintain proper sealing and opening pressure.

How does the Vent plug without filter AKO1 behave if the tank pressure exceeds 0.3 bar?

Vent plug without filter AKO1 will open as tank pressure rises due to oil turbulence, but only once the internal check valve sees pressure between 0.15 and 0.3 bar. If tank pressure exceeds 0.3 bar, the check valve will be fully open, allowing excess gas/air to vent freely through the plug to the atmosphere. The O-ring and washer maintain sealing at lower pressures and prevent contamination during suction; above 0.3 bar the venting function dominates until pressure falls back below the closing threshold. Materials: aluminum body, steel cover, fiber washer; operating range â20Â°C to +100Â°C.

Can the Vent plug without filter AKO1 be installed upside down or only at the top of the tank?

The Vent plug without filter AKO1 is described as an air vent plug with a check valve and O-ring mounted at the top of the tank, which opens during pressure increases (oil turbulence) and prevents contamination entering the system during hydraulic oil suction. Given this design and function, it should be installed at the top of the tank. Reasons: - The check valve and O-ring are positioned to operate with the vent oriented upward so that pressure-driven opening and proper sealing occur as intended. - Installed upside down the check valve and O-ring would not seat or vent correctly, risking improper operation, leakage, or ingress of contaminants. - The productâs operating range and materials (aluminum body, steel cover, fiber washer) do not change the orientation requirement. Conclusion: Install the Vent plug without filter AKO1 at the top of the tank, not upside down.
