FAQ
▔▔
What is the advantage of a 2 spool valve compared to a single spool valve?
A 2 spool valve allows control of two independent hydraulic functions within one valve assembly, reducing piping complexity, space requirements, and installation cost.
How do I choose the correct center condition?
Open center is suitable for fixed displacement pump systems, while closed center is preferred for variable displacement pumps. Tandem center helps reduce heat generation during neutral position.
Can I replace a 2 spool valve from one brand with another?
Yes, but only if mounting standards, port sizes, pressure ratings, and spool functions are fully compatible. Always verify dimensions and functional symbols.
What causes internal leakage in directional control valves?
Common causes include spool wear, contaminated hydraulic oil, improper filtration, or operating beyond pressure limits.
