The Electric Hydraulic Control Valve (600X series) is a solenoid-operated proportional valve designed for accurate regulation of oil flow and pressure in hydraulic systems.

Why Choose Our Electric Hydraulic Control Valve?

Our 600X series Electric Hydraulic Control Valve offers superior accuracy and reliability for demanding hydraulic applications. Manufactured under ISO 9001 standards, each valve is tested before shipment.

Detailed Technical Data

• Maximum operating pressure: 315 bar (4500 psi)
• Maximum flow: 300 L/min (80 GPM)
• Hysteresis: < 3%
• Repeatability: < 1%
• Response time: < 30 ms
• Temperature range: -20°C to +80°C
• Protection class: IP65 (coil)

Installation Instructions

Mount the Electric Hydraulic Control Valve on a clean, flat manifold. Ensure hydraulic oil is filtered to ISO 4406 class 18/16/13. The coil can be rotated 360° for easy wiring. Do not exceed maximum pressure ratings.

Ordering Information

When ordering, please specify: model number, coil voltage, input signal type (0-10V or 4-20mA), and port size. Custom configurations are available upon request.

Quality Assurance

Each valve undergoes a 100% performance test including pressure drop, leakage, and step response. We provide a 12-month warranty.

Technical Specifications

• Size Range: DN15 – DN200 (½” – 8″)
• Pressure Rating: up to 315 bar (4500 psi)
• Flow Rate: up to 300 L/min
• Coil Voltage: 24V DC / 110V AC / 220V AC
• Input Signal: 0–10V or 4–20mA
• Body Material: Cast iron / Steel

Working Principle

This Electric Hydraulic Control Valve converts an electrical input signal into a proportional hydraulic output. When the solenoid receives current, it moves the spool to control the opening size, thereby regulating pressure or flow. Unlike simple on/off valves, the Electric Hydraulic Control Valve provides stepless, precise control.

Applications

• Injection molding machines
• Hydraulic presses
• Test benches
• Mobile hydraulics

FAQ

Q: What is the difference between a proportional valve and a servo valve? A: The Electric Hydraulic Control Valve offers good dynamic response at lower cost, while servo valves provide higher precision but are more expensive.Q: Can this valve be used for water? A: No, it is designed for mineral oil only.Learn more about proportional hydraulics on Wikipedia or Hydraulics & Pneumatics.

Key Features & Benefits
