FAQ
▔▔
What is the difference between a 4/2 and a 4/3 hydraulic valve?
A 4/2 valve has two spool positions, while a 4/3 valve has three positions, allowing an additional neutral or float function.
How do I choose the correct spool type?
Spool selection depends on system design. Closed center is suitable for accumulator systems, open center for fixed displacement pumps, and tandem center for energy efficiency in multi-valve systems.
Can I replace different brands with the same mounting size?
Only if the mounting standard, port layout, pressure rating, and electrical specifications match exactly. Cross-brand replacement should always be verified.
Why should I use original branded hydraulic valves?
Original valves ensure accurate tolerances, reliable sealing, and predictable performance. Non-original parts often lead to leakage, unstable motion, and shorter service life.
