CDB15 Four-Spool Sectional Hydraulic Control Valve for Chinese Mini Excavators

This CDB15 sectional directional-control valve is designed for compatible Chinese mini excavators and other compact hydraulic equipment.

The valve contains four working spool sections for controlling four separate hydraulic functions. The additional end section contains the pump inlet and hydraulic tank return connections—it is not a fifth working spool.

The sectional construction makes this a useful replacement for a damaged, cracked, leaking, or worn original hydraulic control valve.

IMPORTANT—CONTROL HARDWARE NOT INCLUDED

The silver linkage/control hardware shown on the left side of the photographs is not included with this valve.

The valve is supplied with protective caps installed over the spool-control ends. In most applications, these caps must be removed so you can install your existing levers, linkage, joystick controls, cables, or other operating hardware.

INSTALLATION AND SAFETY

Hydraulic repairs should be performed by a qualified person. Shut down the machine and release all stored hydraulic pressure before disconnecting any hoses.

Keep every hose and valve port clean during installation. Incorrect hose routing, incompatible threads, excessive pressure, or an improperly adjusted relief valve can damage the valve or machine and may cause serious injury.

Always confirm correct installation and safe operation before placing the machine back into service.
