Share
Overview: Solving Precision Pneumatic Control Challenges
The SMC VQ0141-5M-C4 solenoid valve addresses a critical industrial challenge: providing reliable, compact pneumatic control in space-constrained automation systems. This 4-way, 5-port directional control valve eliminates the common problems of inconsistent actuator response and flow restrictions in small-scale pneumatic systems. With its compact design measuring just 10.16cm in length and 2.54cm in width, this valve delivers precise air flow management for applications ranging from packaging machinery to medical equipment.
Technical Specifications Analysis
The SMC VQ0141-5M-C4 represents the VQ0 series' engineering excellence, offering superior flow characteristics in a minimal footprint. Here are the detailed technical specifications:
| Specification | Value | Description |
|---|---|---|
| Valve Type | 4-Way, 5-Port | Directional control for double-acting cylinders |
| Operating Fluid | Air/Inert Gas | Compatible with standard industrial air systems |
| Operating Pressure Range | 0.1 - 0.7 MPa | Standard industrial pneumatic pressure range |
| High Pressure Capability | 0.8 MPa | Maximum pressure for intermittent operation |
| Cv Factor (Metal Seal) | 0.15 | Flow coefficient for metal-sealed version |
| Cv Factor (Rubber Seal) | 0.2 | Flow coefficient for rubber-sealed version |
| Coil Type | Flip N/Plug-in (DC) | Easy installation and maintenance |
| Dimensions (L×W×H) | 10.16×2.54×5.08 cm | Ultra-compact footprint |
| Weight | 0.27 kg | Lightweight construction |
| Port Size | M5 | Standard metric thread fitting |
| Voltage Options | 12VDC, 24VDC | Common industrial control voltages |
The valve's Cv factor of 0.15-0.2 provides sufficient flow for most small to medium-sized pneumatic cylinders, while the M5 port size ensures compatibility with standard industrial fittings. The flip-and-plug-in coil design significantly reduces maintenance downtime compared to traditional wired connections.
Buying Considerations: Selection Guide
When selecting the SMC VQ0141-5M-C4 or any solenoid valve for your application, consider these critical factors:
1. Pressure Requirements: Verify your system operates within the 0.1-0.7 MPa range. For higher pressure applications, consider the high-pressure variant or explore other directional control valves in our catalog.
2. Flow Capacity: Calculate your cylinder's air consumption requirements. The Cv factor of 0.15-0.2 suits cylinders with bore sizes up to 32mm at standard operating speeds.
3. Voltage Compatibility: Ensure your control system provides either 12VDC or 24VDC. Mismatched voltage can damage the coil and affect valve performance.
4. Environmental Conditions: The VQ0141-5M-C4 operates in standard industrial environments. For extreme temperatures or hazardous locations, consult our specialists for appropriate industrial valves with enhanced protection.
5. Port Configuration: The 4-way, 5-port design controls double-acting cylinders. For single-acting cylinders, consider 3-way valves available in our pneumatic components section.
6. Maintenance Considerations: The plug-in coil design allows quick replacement without disturbing piping. Stock spare coils for critical applications to minimize downtime.
Frequently Asked Questions
Q1: What is the maximum operating frequency for the SMC VQ0141-5M-C4?
The VQ0141-5M-C4 typically operates at frequencies up to 5 Hz (300 cycles per minute) under standard conditions. Higher frequencies may require additional considerations for heat dissipation and may benefit from consulting our technical team for high-speed valves.
Q2: Can this valve be used with lubricated air systems?
Yes, the SMC VQ0141-5M-C4 is compatible with both lubricated and non-lubricated air systems. However, consistent lubrication is recommended for optimal seal life and performance in continuous operation applications.
Q3: What is the expected service life of this solenoid valve?
Under normal operating conditions with clean, dry air, the SMC VQ0141-5M-C4 typically achieves 10+ million cycles. Service life can be extended through proper filtration and regular maintenance of your pneumatic filtration system.
