# 4WE10D31B/CG24N9Z5L Solenoid Operated Directional Spool Valve
## Overview
The 4WE10D31B/CG24N9Z5L is a direct-acting wet-armature solenoid directional valve within the 4WE10 series. This 4/2-way D-spool configuration features spring return, a 24 VDC coil, and a Z5L electrical connector with built-in LED status indicator. Designed to ISO 4401-05 (NG10 / CETOP 05) subplate mounting standards, it offers full interchangeability with equivalent Rexroth and Huade style valves.
This hydraulic control valve is engineered to regulate the travel direction, start and stop functions of hydraulic cylinders and hydraulic motors across industrial hydraulic circuits. The wet solenoid design delivers consistent shifting performance, low acoustic noise, and is rated for 100% continuous duty cycle (100% ED). An integrated manual override allows on-site commissioning and functional testing without power supply.
This product is ISO9001 and CE certified to meet international quality and safety requirements.
