Material Composition

• Valve‑body: High‑strength cast‑steel
• Spool: Precision‑grinded alloy‑steel
• Solenoid housing: Steel‑alloy
• Sealing‑elements: Nitrile‑rubber / fluorine‑rubber
• Spring: High‑elastic alloy‑steel

Structural Features

• Monoblock cast‑steel valve‑body
• Precision‑fit‑clearance spool‑valve core
• Double‑side wet‑pin replaceable solenoid coil
• Built‑in return‑spring
• Hidden manual‑override push‑button
• Standard sub‑plate mounting‑hole‑layout

Working Principle When solenoid coil is energized, electromagnetic‑force pushes spool‑valve‑core to shift position. Switch internal oil‑port connection‑relationship inside valve‑body. Change hydraulic‑oil flow‑direction. After power‑off, return‑spring pushes spool‑core back to neutral‑position. Manual‑override can push spool‑core mechanically for commissioning‑test without solenoid energization.

Functional Features

• Hydraulic‑oil flow‑direction switching
• Start‑stop control for hydraulic‑actuator
• Replaceable solenoid‑coil without opening pressure‑chamber
• Manual‑override for commissioning
• Wet‑pin solenoid for long service‑life
• Compatible with standard size‑6 sub‑plates

Application Scenarios

• General‑purpose hydraulic‑machine‑tool
• Metallurgical‑hydraulic‑equipment
• Packaging‑machinery hydraulic‑station
• Injection‑molding‑machine auxiliary‑hydraulic‑circuit
• Material‑handling hydraulic‑system
• Light‑industry mechanical‑hydraulic‑control

Installation Requirements

• Mount on standard NG6 sub‑plate
• Tighten mounting‑bolt with specified torque
• Ensure sub‑plate surface flat‑ness and cleanliness
• Install hydraulic‑pipe according to port‑marking
• Assemble complete electrical‑connector to achieve IP65 protection
• Set correct hydraulic‑oil‑filtration precision

Usage Precautions

• Keep hydraulic‑oil cleanliness in accordance with component‑requirement
• Avoid long‑term over‑pressure operation
• Solenoid‑coil must not work under over‑voltage
• Manual‑override only for short‑time commissioning
• Replace sealing‑parts regularly according to working‑condition
• Prevent external mechanical‑impact to valve‑body and solenoid
