Product Questions & Answers (6)

Question by: Harold C on Jul 27, 2025, 7:00 AM

I need a relief valve that can handle up to 3000 PSI. Will this one do the trick?

Answer by: Customer Support on Jul 29, 2025, 6:26 AM

Designed for systems requiring precise pressure control, this 3-port relief valve is rated up to a maximum operating pressure of 3000 PSI, so it should work well for your application.

Question by: Dwight P on Dec 4, 2025, 9:59 AM

Got a system running at about 2200 PSI and need a relief valve that'll handle that without being right at the top of its range. This one go up to 3000?

Answer by: Customer Support on Dec 6, 2025, 6:51 AM

Rated up to 3000 PSI, so 2200 gives you a comfortable margin before you're anywhere near the ceiling. The adjustable range starts at 150 PSI and runs the full way up, so you can dial it in right where your system needs it. Adjustment is made through a screw underneath a removable cap, which keeps it from getting bumped out of setting during normal operation.

got a skid steer attachment that needs a simple in-line relief. is this one adjustable from 150 up to 3000 psi?

Answer by: Customer Support on Dec 15, 2025, 3:36 PM

For setting pressure, it covers an adjustable range of 150 to 3000 PSI, and the adjustment is made with a screw that sits underneath a removable cap.

Question by: Travis T on May 21, 2025, 12:03 PM

Will this handle a constant workload or is it more for occasional use?

Answer by: Customer Support on May 23, 2025, 11:32 AM

This valve is built with precision components to ensure reliable performance and longevity in hydraulic systems needing consistent pressure regulation.

Question by: Tommy S on Feb 3, 2026, 6:11 AM

adjustment screw, is that something you can get to without pulling the whole valve out of the line?

Answer by: Customer Support on Feb 4, 2026, 12:23 PM

The screw sits underneath a removable cap, so you can reach it while the valve stays in place. No need to break the line or pull anything apart just to dial in your pressure setting. That makes field adjustments a whole lot more practical on a working machine.

Question by: Cody M on Apr 8, 2025, 2:25 PM

got a power unit with 1/2 npt lines. are the ports on this relief valve both 1/2 npt, or am i gonna need adapters

Answer by: Customer Support on Apr 10, 2025, 6:57 AM

Port sizing is straightforward on this one. The pressure port is 1/2 NPT and the tank port is also 1/2 NPT, so it matches 1/2 NPT hydraulic connections on both connections.
