723-40-92103 Excavator Main Control Relief Valve for PC200-8

Product Introduction

723-40-92103 Excavator Main Control Relief Valve for PC200-8 The main relief valve is installed on the main control valve, usually two. This valve sets the maximum pressure for the entire hydraulic system to work. When the system pressure exceeds the set pressure of the main gun, the main gun opens the oil return tank oil circuit to overflow the hydraulic oil back to the oil tank to protect the entire hydraulic system and avoid excessive oil circuit pressure.
