II. Core Hydraulic Parameters

Rated Flow Rate: 160L/min @ ΔP = 7MPa (single chamber pressure difference 70bar)

System Supply Pressure: Standard 21MPa (210bar), Maximum Pressure Resistance 350bar

Installation Standard: ISO4401-07 (07 specification flange installation)

Pilot Control: Internal Control X/Y (built-in pilot oil, no need for external control oil), Return Oil Dual T-junction Design

Neutral Function: O-type Zero Opening Linear Valve Core, Zero Position Leakage is Small, Control Linearity is Good

III. Electrical Specifications

Power Supply: **DC24V (18～32VDC)** Valve Body Built-in Amplifier Board

Standard Control Commands: ±10VDC Analog Signal (Optional 4-20mA Current Signal)

Valve Core Closed Loop: Built-in LVDT Displacement Electrical Feedback (Same as your previous D662-3710E's E Electrical Feedback Structure)

Step Response: 10～13ms (21MPa System Pressure), Excellent High-Frequency Dynamic Performance

IV. Application Scenarios

Mainly for Injection Molding Machines: Injection Speed, Holding Pressure, Melting Gel Back Pressure Closed Loop Control; Slightly used in Die Casting Machines, Material Fatigue Test Machines, and Small and Medium-sized Hydraulic Simulation Platforms.
