In-Depth Model Analysis
1. Model Code Breakdown
- VX23: Series code, representing a direct-acting 2-port solenoid valve, Size 3 (corresponding to Rc3/8 port size).
- 2: Represents a 2-port valve (2 ports: inlet P, outlet A).
- E: Material and port size code, indicating the valve body material is C37 (aluminum bronze) and the port size is Rc3/8.
- G: Electrical specification code, representing DC24V voltage, with a DIN-type connector lead-out style and overvoltage protection circuit.
2. Core Features & Advantages
- Universal Media Compatibility: Benefiting from the excellent corrosion resistance of C37 material, this valve can handle not only air but also directly manage water, oil, vacuum systems, and low-to-medium pressure steam (or warm water), eliminating the need for frequent valve body material changes and greatly simplifying spare parts management.
- Zero Pressure Differential Operation: The direct-acting design ensures reliable operation even at zero system pressure (vacuum) or minimal pressure differentials, making it particularly suitable for vacuum cup systems or low-pressure water circulation systems.
- High Flow Performance: As a Size 3 valve body, it features a large flow area (high Cv value), meeting control requirements for higher flow rates and reducing system pressure drop.
- Protection & Safety: The DIN-type connector offers convenient wiring and incorporates an overvoltage protection circuit, effectively preventing coil burnout caused by voltage fluctuations or surges.
3. Typical Application Scenarios
- Water Treatment Systems: Controlling the on/off flow of industrial cooling water or cleaning water.
- Vacuum Systems: Used for on/off control in vacuum cups or vacuum generators.
- Oil Circuit Control: Serving as a switching valve in hydraulic stations or lubrication circuits.
- Steam/Hot Water Circuits: Controlling media flow in equipment requiring temperature control or steam heating.
Selection & Usage Recommendations
- Confirm Media Characteristics: While this valve is compatible with various media, when handling high-temperature steam (>100°C) or highly corrosive media, it is recommended to further verify the temperature resistance curves and material compatibility provided in the catalog.
- Power Supply Matching: The suffix “G” typically defaults to DC24V. For other voltages (e.g., AC220V), select the corresponding suffix code (such as “A” or “D”).
- Installation Orientation: Direct-acting solenoid valves have specific orientation requirements. Horizontal installation (coil facing upward) is generally recommended to ensure smooth valve core operation.
- Upstream Filtration: Although the C37 material is corrosion-resistant, when used in water or oil circuits, installing a filter upstream of the valve is still recommended to prevent solid particles from jamming the valve core.
Summary
The SMC VX232EG is a highly versatile direct-acting 2-port solenoid valve. Its core value lies in the corrosion resistance of the C37 material and its adaptability to all media. For complex industrial environments requiring the handling of multiple fluids like air, water, and oil within a single machine, choosing this valve can significantly reduce selection complexity and spare parts inventory. Simultaneously, the zero pressure differential operation enabled by its direct-acting structure gives it an irreplaceable advantage in vacuum and low-pressure systems.
