Working Principle
The VK332V-5DZ-01-F employs a direct-acting poppet structure. When the solenoid coil is energized, the electromagnetic force directly attracts the valve plunger, changing the on/off state of the fluid passage. The valve body features a 3-port design: P port (pressure inlet), A port (working port), and R port (exhaust port). As the plunger moves, it switches the fluid flow between P→A or A→R, thereby controlling the action of pneumatic actuators. When de-energized, the electromagnetic force ceases, and the spring force returns the plunger to its initial position.
Typical Application Scenarios
- Industrial Automation Lines Used to control the directional motion of pneumatic actuators like cylinders and grippers in automated production lines (e.g., automotive manufacturing, electronics assembly), enabling tasks like workpiece pushing, positioning, clamping, and transferring, thereby improving production efficiency and product quality.
- Packaging Machinery Controls actions like material conveying, sorting, and marking on packaging machines. The solenoid valve enables precise directional control of pneumatic actuators, ensuring accuracy and stability in the production process.
- Robotics Serves within robotic pneumatic control systems to control the directional motion of pneumatic actuators, enabling tasks like workpiece gripping, positioning, and placement, increasing robot motion precision and efficiency.
- Precision Manufacturing Equipment In equipment for semiconductor manufacturing, precision machining, etc., used to control the action precision of pneumatic actuators, ensuring process stability and repeatability, thereby enhancing product quality.
Installation and Usage Precautions
- Installation Requirements The solenoid valve should be installed on a flat, stable base to ensure stable operation. Before installation, verify that the air supply pressure meets the 0~0.7 MPa requirement and that the air source is clean. During installation, pay attention to the valve’s port direction; the arrow on the valve body should align with the medium flow direction and must not be reversed. P is the pressure inlet, A(B) is the working port, and R(S) is the exhaust port.
- Operating Environment Operating temperature range is -5~50°C. Avoid use in extremely high or low temperatures. Relative humidity should be maintained within an appropriate range to prevent moisture from affecting equipment lifespan. The operating medium should be filtered through a 40μm or finer filter before use.
- Electrical Connection Wire strictly according to the voltage parameters on the nameplate (power supply voltage DC24V) and ensure a stable power supply. When connecting wires, ensure connections are secure to prevent solenoid valve malfunction due to loosening. It is recommended to install an overload protection device in the circuit.
- Regular Maintenance Regularly inspect the solenoid valve’s connecting piping and valves to ensure no leaks. Periodically clean the valve surface to keep it clean. Regularly check the valve’s operational performance to ensure long-term stable operation. After prolonged shutdowns, it’s recommended to perform an air purge before restarting.
- Safe Operation Ensure equipment is properly grounded before operation to prevent electric shock risks. Avoid contact with moving parts during operation to prevent pinching injuries. In case of equipment malfunction, stop immediately and have repairs performed by qualified personnel. Depressurize before installation to prevent injury from high-pressure medium ejection. Strictly avoid using the product beyond its rated pressure, temperature, and medium specifications.
