Product Questions & Answers

reckon this'll work alright with some hydraulic equipment running around 1800 PSI? Don't wanna blow nothin' up.

Question by: Rex E on Nov 2, 2025, 10:47 AM

This valve can handle pressures up to 2000 PSI, so it should work fine in your setup as long as you stay below that limit. Just be sure your system doesn't have pressure spikes that could exceed the valve's rating.

Running this on a pneumatic setup, does the brass body hold up okay, or should I be looking at one of the steel versions?

Question by: Cheryl G on Nov 26, 2025, 9:33 AM

Brass versions are rated for pneumatic systems and lower pressure hydraulic applications, so if you're staying in that territory you're fine. The 2000 PSI max and 13.50 GPM flow capacity cover a solid range of pneumatic work. Steel builds are really meant for heavier hydraulic duty. Stick with brass for air and you won't have any issues.
