GVO PRRS-08 Pilot Relief Valve Oil Source Valve Pressure Safety Relief Valve for SY XE60 75 135 150 Excavators

Key attributes

Fast Response & Effective Protection
During sudden pressure spikes – such as those caused by rock breaking or heavy-load digging – the valve opens rapidly to divert excess hydraulic oil back to the tank. This quick response effectively absorbs pressure peaks, protecting the hydraulic pump, cylinders, and hoses from damage, and significantly reducing the risk of equipment failure.
