Product Questions & Answers

what's the max pressure this valve handles and is 3000 PSI enough for most standard hydraulic setups on farm equipment or skid steers?

Question by: Brett P on Jan 15, 2026, 10:48 AM

Rated at 3000 PSI, this valve covers the operating range of most agricultural and light construction hydraulic systems without issue. Skid steers, log splitters, and similar equipment typically run well under that ceiling, so you'd have plenty of headroom for everyday use. The flow rating is 18 GPM, which also lines up with what most mid-sized hydraulic systems push through a control valve like this.

got a valve bank spot that’s tight. how big is this one and what’s it made out of

Question by: Curt F on May 15, 2025, 9:41 PM

Compact and light is the main idea with this monoblock style valve, so it fits well where space is limited. The body is cast iron, and it uses a precision ground chrome plated steel spool with Buna-N O-rings and a black nylon ball knob.
