Festo VSVA-B-M52-A-A2-1C1 Solenoid Valve (Order No. 546691)
1. Product Overview
The Festo VSVA-B-M52-A-A2-1C1 (Order No. 546691) is a high-performance 5/2-way directional control solenoid valve from Festo’s VSVA series, a benchmark line of modular pneumatic valves engineered for precision and reliability in industrial automation systems. As a core component of pneumatic control circuits, this valve is dedicated to regulating the flow direction and on-off state of compressed air, enabling accurate actuation of pneumatic actuators (cylinders, grippers, air motors) across automotive manufacturing, electronic assembly, packaging machinery, automated material handling, and high-precision processing equipment.
Featuring a bistable double solenoid actuation design (no return spring) and an ultra-compact slim profile, it supports both decentralized mounting (directly on actuators to reduce piping) and centralized integration (on Festo VSVA series manifolds) for space-constrained control panels. Constructed with corrosion-resistant high-grade materials and precision-machined internal components, it delivers consistent, long-lasting performance in harsh industrial environments with temperature fluctuations, dust, and mild moisture. The valve operates on 24 V AC power, supports lubrication-free operation to avoid workpiece/equipment contamination, and complies with international industrial standards (VDMA 24364, RoHS). With ultra-fast switching, low air leakage, and energy-efficient bistable operation (no continuous power for position holding), it is an ideal solution for high-speed, high-precision automation processes requiring stable and efficient pneumatic control.
2. Main Functions
表格
| Function | Detailed Description |
|---|---|
| 5/2-Way Pneumatic Direction Control | Precisely switches compressed air flow between two working positions to drive bidirectional motion of pneumatic actuators (e.g., extend/retract cylinders, open/close grippers), enabling cyclic and sequential automation with high repeatability. |
| Bistable Double Solenoid Operation | Dual 24 V AC solenoids enable position locking: the valve switches when one solenoid is energized and remains in that position until the opposing solenoid is activated—no continuous power required, reducing energy consumption and ensuring position holding during temporary power loss. |
| Ultra-Fast Response Actuation | Optimized internal spool and flow channel geometry deliver rapid switching times, enabling fast actuation of pneumatic components and improving the cycle efficiency of high-speed automation lines. |
| Lubrication-Free Operation | Fully compatible with dry, filtered compressed air (per ISO 8573-1:2010 [7:4:4]), eliminating the need for oil lubrication and avoiding contamination—ideal for clean applications (electronics, food processing, surface treatment). |
| Low-Leakage Airtight Performance | High-precision FKM/NBR seals and machined spool/valve body mating surfaces minimize air leakage, reducing compressed air waste, lowering energy costs, and maintaining stable system pressure for reliable actuator control. |
| Modular Manifold Compatibility | Seamlessly integrates with Festo VSVA series valve manifolds, enabling centralized installation of multiple valves to save space, simplify piping/wiring, and streamline maintenance and system expansion. |
| Corrosion-Resistant Industrial Operation | Robust material construction (anodized aluminum, stainless steel) resists mild industrial corrosion, dust, and moisture, ensuring consistent performance in factory environments with variable operating conditions. |
| Standardized Universal Integration | Equipped with standardized G1/4 pneumatic ports and M12×1 5-pin electrical connectors, ensuring full compatibility with Festo’s pneumatic components (actuators, fittings, sensors) and other industrial standard automation equipment. |
