Narrative:

Descending via the eagul arrival runway 26 in VFR smooth conditions encountered moderate wake turbulence from preceding 737 estimated at 7 miles ahead. Seatbelt sign was off but turned on at first indication of wake. Coordinated with ATC for a 1 nm offset. Prior to the offset encountered wake a second time. No injuries. I did not make the flight attendant turbulence commands over the PA because it happened so fast and my attention was on aircraft control and I didn't have time. The bank rolled left and right but we did not exceed any limitations. The first encounter only kicked off the LNAV and the second kicked off the autopilot because it could not control the bank. Made reassuring PA after verifying flight attendant was safe and no injuries.

Title: B737NG Captain reported encountering wake turbulence on arrival into PHX in trail of a B737.

Narrative: Descending via the EAGUL arrival runway 26 in VFR smooth conditions encountered moderate wake turbulence from preceding 737 estimated at 7 miles ahead. Seatbelt sign was off but turned on at first indication of wake. Coordinated with ATC for a 1 nm offset. Prior to the offset encountered wake a second time. No injuries. I did not make the FA turbulence commands over the PA because it happened so fast and my attention was on aircraft control and I didn't have time. The bank rolled left and right but we did not exceed any limitations. The first encounter only kicked off the LNAV and the second kicked off the autopilot because it could not control the bank.
