1. Model Interpretation (MPW-03-2-20)
MPW
• M: Likely denotesModular DesignorMagnetic Control(common in hydraulic valve classification).
• P: Typically refers toPressure ControlorProportional Control(requires functional confirmation).
• W: May representWet Solenoid(electromagnet submerged in hydraulic oil), suitable for high-frequency or harsh environments.
03
• Port Size/Flow Rating: Could indicate3mm portsor a3L/min flow range(manufacturer-specific).
• Series Number: Some brands use digits to distinguish product series (e.g., third-generation design).
2
• Valve Configuration: Usually denotes2-position (2/2), meaning the spool has two operational states (e.g., open/closed).
• Function Type: May be2/2-wayor2/3-way(requires valve body verification).
20
• Pressure Rating: Commonly represents20MPa (200bar)nominal working pressure, suitable for medium-high-pressure systems.
• Version Number: Rarely, it may indicate product iteration (e.g., Version 20).

2. Key Performance Parameters (Manufacturer Confirmation Required)
【表格】
Parameter Typical Value Description
Rated Pressure 20MPa (200bar) Maximum allowable working pressure; system pressure must ≤ rated value.
Flow Range 3–30 L/min Depends on port size and spool design; larger flows require bigger ports.
Control Method Solenoid/Manual "W" likely indicates wet solenoid for high-frequency switching; some models support manual override.
Response Time ≤10ms (solenoid valve) Time from solenoid energization to full spool shift.
Operating Temp. -20°C to +80°C Seal material and fluid compatibility range.
Port Type Thread/Flange Connection Common: G1/4, M18×1.5 threads, or DIN 24340 flanges.
Media Compatibility Mineral-based hydraulic oil, anti-wear fluid Verify compatibility with water-based or synthetic fluids.

3. Common Valve Structures & Functions
2/2-Way Valve
• Function: Controls fluid on/off (e.g., clamp locking/releasing).
• Applications: Simple hydraulic circuits, pneumatic system alternatives.
2/3-Way Valve
• Function: Directs fluid flow (e.g., single-acting cylinder control).
• Applications: Lifting platforms, agricultural machinery hydraulic outputs.
Wet Solenoid Characteristics
• Advantages: Better heat dissipation via oil immersion, longer lifespan, suitable for frequent cycling.
• vs. Dry Solenoid: Higher dust resistance but slightly lower heat dissipation efficiency.
