B757 pilot reported left hydraulic system failure during descent. Flight crew landed and after clearing runway was towed to ramp.

Narrative

While at 9000 feet; just before descent into ZZZ; we got an EICAS message; L HYD QTY. The left hydraulic system showed basically zero quantity. We received subsequent EICAS messages of RUDDER RATIO; L HYD SYS PRESS and L HYD RSVR PRES. We performed the QRH procedure for L HYD QTY. As per procedure; we turned off left engine and left electric hydraulic pumps; reviewed lost systems and prepared for a flaps 20 landing and planned for the possibility of manual gear and flap extension; as well as loss of nose wheel steering. We reviewed checklist for subsequent EICAS messages; reviewed landing distance data and sent an ACARS message to Dispatch about the left hydraulic system loss and that we were landing ZZZ. We requested priority handling with ATC and advised of our situation. We requested a long final for vectors to ILS runway XX to get configured and also requested to have emergency equipment standing by. We were able to configure flaps and gear via normal means. We landed; rolled out and were able to use nose wheel steering to exit the runway. Once we were on the taxiway; we lost nose wheel steering and stopped to call for a tow to the ramp.According to ZZZ maintenance; the left hydraulic system filter bypass valve had blown off causing the system quantity and pressure loss which required its replacement and 10 gallons of hydraulic fluid.
