Question by: Harvey K on Jan 26, 2026, 6:56 AM

What kind of flow can this FPR 3/4 -UNF 5 handle, and is it actually rated high enough for a refuse hauler running hard every day?

Answer by: Customer Support on Jan 27, 2026, 12:15 PM

For refuse hauler work, the numbers here are solid. The valve is rated for a maximum flow of 227 liters per minute, which is 60 US GPM, and it holds up to 350 bar or 5000 psi. The 85 liters per minute figure listed is the standard operational flow rate. So there's genuine headroom above that for demanding cycles. The poppet-style design also keeps efficiency up and spring resistance low, which matters when you're running a system hard through a full shift.
