Hydraulic Main Control Valve 340-3466 for M315 M313D Wheel Excavator

This hydraulic main control valve, part number 340-3466, is the primary hydraulic distribution unit specifically engineered for the hydraulic system of M315 and M313D wheel excavators. It distributes high-pressure hydraulic oil to control the boom, arm, bucket, travel, and swing movements. Featuring a multi-channel valve block structure, precisely matched spools, wear-resistant alloy materials, and precision machining, it offers direct replacement installation and stable flow control performance for heavy-duty construction conditions.

• Internal spool and valve body wear, leading to pressure drop and weak action
• Internal seal failure, resulting in hydraulic oil leakage
• Abnormal noise and vibration during operation
• Spool sticking, causing control failure and action lag
• Valve block cracking caused by overload and high pressure

• Confirm the part number and machine serial number before ordering
• Check oil port specifications, mounting dimensions, and control type
• Request strict pressure and performance testing before shipment
• Shockproof wooden packaging to prevent transit damage
• Quality warranty covering manufacturing defects
