Huade HD-2WRCE32-50S-2X Cartridge Valve: Core Information & Technical Analysis
I. Product Positioning & Core Advantages
1. High-Frequency Response Characteristics
• Designed for hydraulic systems requiring rapid dynamic response, such as injection molding machines, die-casting machines, and hydraulic presses.
• Minimizes delay between signal input and valve core movement through optimized flow path design and solenoid response speed.
2. Two-Port Cartridge Structure
• Adopts standardized cartridge design for direct integration into valve blocks, saving installation space and simplifying hydraulic circuit layouts.
• Supports logic control functions (e.g., directional control, pressure holding) to replace complex traditional valve assemblies.
3. Pressure & Flow Parameters
• Rated Pressure: Typically up to 35 MPa (refer to product manual for specifics), suitable for medium-to-high-pressure systems.
• Flow Range: Matches valve port size (e.g., 32-port diameter), supporting high-flow applications (hundreds of L/min).
II. Technical Features & Performance Metrics
1. Solenoid Drive Technology
• Utilizes wet-type solenoids to enhance response speed and reduce power consumption.
• Supports PWM (Pulse Width Modulation) signal control for precise valve core positioning.
2. Sealing & Reliability
• Precision gap matching between valve core and sleeve minimizes internal leakage and extends service life.
• Seal materials compatible with various hydraulic oils, operating in temperatures from -20°C to +80°C.
3. Electrical Interface
• Features DIN 43650 standard electrical connectors for quick assembly and error-proof design.
• Compatible with 12VDC/24VDC control voltages, adaptable to PLC or dedicated controllers.
III. Typical Application Scenarios
1. Injection Molding Equipment
• Controls rapid cylinder reversal for synchronized mold opening/closing and injection actions.
• Reduces hydraulic shock via high-frequency response, improving product surface quality.
2. Die-Casting Machine Systems
• Enables fast pressure switching during clamping, injection, and ejection cycles, shortening cycle times.
• High-pressure design withstands aluminum/magnesium die-casting environments.
3. Hydraulic Presses & Test Benches
• Facilitates closed-loop pressure control for precise force/displacement loading.
• Cartridge structure simplifies integration into multi-channel control systems.
IV. Selection & Usage Recommendations
1. Parameter Matching
• Select valve port size (e.g., 32-port for HD-2WRCE32) based on system maximum pressure and flow.
• Verify compatibility of control voltage and signal type (PWM or analog) with the controller.
2. Installation & Maintenance
• Clean valve block bores before cartridge insertion to prevent contaminants from entering valve core gaps.
• Regularly check hydraulic oil cleanliness (recommended NAS 6 or better) to avoid valve core sticking.
3. Troubleshooting
• No Action: Inspect power supply, signal wiring, and solenoid coil resistance.
• Slow Response: Confirm hydraulic oil viscosity is not excessive or valve core worn.
• Leakage: Replace seals or inspect valve body for surface scratches.
