Product Questions & Answers

Got a harvester that's been giving us grief with load drift on the boom circuit. Would the 1SEB90F20S4-SP1600 be a fit for that kind of application?

Question by: Phil H on Feb 1, 2026, 4:09 PM

Load holding on harvester boom circuits is exactly what the 1SEB90 Series was built around. It carries ISO 8643 compliance, which is the standard specifically tied to that type of mobile equipment use. The pilot-assisted relief with integrated check keeps the load stable when the circuit isn't actively moving, so drift from pressure bleed-down is controlled. At 350 bar and flows up to 550 L/min, it has plenty of headroom for demanding boom work.

If I'm usin' this on a refuse hauler, can it handle the constant up and down pressure all day long?

Question by: Chad M on Apr 20, 2025, 12:45 PM

This valve is built to provide excellent load-holding stability, even with demanding duty cycles like those found in refuse haulers. Its pilot-assisted relief and integrated check valve design help maintain precise control.
