Festo VUVG-LK14-B52-T-G18-1H2L-W1-S 5/2 Bistable Solenoid Valve

Technical Overview

The Festo VUVG-LK14-B52-T-G18-1H2L-W1-S (Part Number 589288) is a highly efficient 5/2 bistable pneumatic solenoid valve engineered for advanced industrial automation. Featuring an electrically actuated piston slide mechanism with a soft sealing ring, it provides a substantial nominal flow rate of 660 l/min within an ultra-compact 14 mm valve size. Operating reliably on 24V DC control voltages and dynamic working pressures between 0.15 MPa and 0.7 MPa, this pilot-actuated valve utilizes standard G1/8 pneumatic working ports. It ensures precise bidirectional control for double-acting cylinders and pneumatic actuators, boasting an IP40 protection rating and UL recognition for versatile integration into manufacturing, robotics, and complex material handling systems.

Industrial Applications

1. Automated Packaging Lines

In high-speed packaging equipment, sorting and pushing mechanisms require fast, repeatable actuation to maintain throughput. The 5/2 bistable solenoid valve controls double-acting pneumatic cylinders efficiently using standardized 24V DC signals from the system PLC.

Problem Solved

Prevents pneumatic cylinders from losing their mechanical position if electrical power fluctuates or is temporarily cut, avoiding severe mechanical jams while delivering a high 660 l/min flow for aggressive cycle times.

2. Robotic End-of-Arm Tooling (EOAT)

Industrial robotic arms utilize pneumatic grippers, vacuum generators, and rotary actuators for material handling, requiring valves mounted as close to the point of use as possible to minimize pneumatic latency.

Problem Solved

The exceptionally compact 14 mm valve footprint allows for direct, localized installation on the robotic manipulator itself, drastically reducing air line lengths and maximizing the robot's dynamic payload capacity due to its lightweight profile.

3. Conveyor Routing and Diverter Gates

Logistics and industrial conveyor systems utilize pneumatic diverters to change the routing of packages, totes, or products based on barcode scanner data or vision system inputs.

Problem Solved

The valve's ability to operate smoothly at varying line pressures (0.15 to 0.7 MPa) ensures strong and absolute routing gate actuation. Its internal piloting and soft sealing provide non-reversible flow control that strictly maintains diverter integrity under continuous 24/7 operation.
