FAQ

What is the function of a logic element like the SV 30 in a hydraulic circuit?

Logic elements, or cartridge valves, are versatile components used for directional, pressure, or flow control functions. This SV 30 is a check valve, allowing free flow in one direction (B to A) and blocking flow in the reverse direction, preventing backflow and maintaining pressure.

Can this SV 30 PA 3-42 valve be used with different hydraulic fluids?

This valve is typically designed for use with mineral oil-based hydraulic fluids (HL, HLP) according to DIN 51524. For use with other fluids like synthetic esters or water glycols, it is crucial to verify the compatibility of the seals. Standard seals are NBR, but FKM (Viton) seals may be required for other media.

The label shows FD: 08W48. What does this indicate about the valve’s service life?

The FD code ’08W48′ indicates the manufacturing date was the 48th week of 2008. While hydraulic valves like this have a long potential service life, the condition of the internal seals can degrade over time, especially if stored improperly. It’s recommended to inspect and potentially replace seals before installation in a critical application.
