Product Questions & Answers (2)

Question by: Denise Y on Nov 29, 2025, 2:58 PM
got a tight spot on my hydraulic line. is this the kind where you can tweak the flow while the system’s still pressurized, then lock it in?
Answer by: Customer Support on Nov 30, 2025, 7:12 PM
Adjustment can be made under pressure on this valve, and once you have the flow where you want it you can lock the setting with the set screw. The easy read color bands and numeric readout are there to help you come back to the same setting later.
Question by: Carl F on Dec 10, 2025, 9:53 PM
What kind of fluid can I run through this valve? I'm working with a hydraulic setup.
Answer by: Customer Support on Dec 12, 2025, 1:20 PM
Since the body is made of steel, it's best suited for hydraulic systems. Brass valves are better for pneumatic or lower-pressure hydraulic setups.
