Product Overview
The VF/VZ series solenoid valves are internally piloted pneumatic control components designed specifically for industrial automation applications. They include various models such as VF3130, VF3230, VF33 (4/5) 30, VF5120, VF5220, VF53 (4/5) 50, VZ5120, VZ5220, and VZ53 (3/4) 50, covering both 2-position 5-way and 3-position 5-way valve configurations. These valves accommodate different flow requirements and can meet the control needs of various industrial pneumatic circuits.

Operating Principle

1. When the solenoid coil is energized, it generates electromagnetic force, driving the pilot spool to move and opening the pilot air path;
2. The pilot air pressure then pushes the main spool to shift, enabling switching among the inlet, outlet, and exhaust channels;
3. With 2-position 5-way or 3-position 5-way structures, these valves can adapt to diverse control requirements such as direction change and pressure maintenance for single-acting or double-acting cylinders;
4. Upon power loss, the spools return to their initial positions, restoring the original air circuit configuration, supporting up to five high-frequency continuous operations per second.

Core Advantages and Selling Points

1. Comprehensive coverage across multiple specifications: ranging from VF3130 to VZ53 (3/4) 50, with effective flow areas spanning 9mm² to 25mm² (CV values from 0.50 to 1.40), catering to varying flow demands;
2. Stable and reliable performance parameters: operating pressure of 0.15–0.8MPa, maximum withstand pressure of 1.2MPa, and a wide temperature range of -5°C to 50°C, suitable for most industrial production environments;
3. Fast response and high-frequency operation: with an excitation time as short as 0.05 seconds, supporting up to five high-frequency cycles per second, meeting the continuous operational needs of automated production lines;
4. Low power consumption: featuring a low-power design of AC 5.5VA and DC 4.8W, ensuring energy efficiency during prolonged operation and reducing equipment energy costs;
5. Flexible wiring options: supporting either lead-out or terminal-type wiring, adapting to diverse installation and cabling requirements for different devices, making installation convenient and efficient.
