3/4 Spool Electro-Hydraulic Directional Control Valve, Solenoid Operated Multi-Way Valve

1. Product Overview

Electro-solenoid operated multi-way directional valve is an integrated hydraulic control component with modular spool body and electromagnetic driver. 3-spool & 4-spool versions are mainstream specifications. Solenoid energization/de-energization pushes spool for circuit shifting to remotely control hydraulic cylinders and motors, replacing traditional manual lever for automated hydraulic system. Modular splicing design allows flexible spool quantity adjustment, built-in relief valve for overpressure protection to avoid system breakdown. Heat-treated valve body improves wear resistance for outdoor harsh working conditions like sanitation and construction sites.

2. Key Product Features

2-1 Solenoid Electric Control: Standard 12VDC/24VDC coil for remote electric control, ideal for automatic vehicle refitting; optional emergency manual override for operation when power cut off.

2-2 Modular Spool Design: Customizable spool sections from 1 to10, 3/4 sections in stock for quick delivery.

2-3 Built-in Overload Relief Valve: Each spool equipped with relief function to release extra pressure automatically, protect hydraulic cylinder and power unit.

2-4 Low Internal Leakage: Precision ground spool plus high-quality oil-resistant seals, minimizing leakage to reduce energy loss.

2-5 Durable Valve Body: Phosphated cast iron housing with anti-rust coating, good contamination resistance for dirty working environment.
