what's the pressure range on this relief valve, and is that adjustment locked down with something or just a bare screw?
Answer by: Customer Support on Jul 24, 2025, 6:40 AM
The adjustment range runs from 60 to 4500 PSI, and yes, it locks down with a screw and locknut setup. That locknut keeps the setting from drifting once you've got it dialed in, which matters a lot on equipment that sees vibration or repeated pressure spikes.
