SMC has introduced the VPX400 series of safety exhaust valves, designed to ensure superior safety in industrial pneumatic systems through rapid air exhaust. The VPX400, ideal for emergency stop scenarios, quickly discharges residual air, reducing the risks associated with stored pneumatic energy and enhancing operator safety.

Dual - Redundant System for Safety

In emergency stop situations, the VPX400 swiftly exhausts air from the secondary side of the valve, safely removing pneumatic energy from the connected equipment. Equipped with a dual - redundant system, the valve continues to function normally even if one valve fails, making it a reliable safety solution for applications with identified residual air pressure risks.

Compliance with ISO Standards

The VPX400 fully complies with the ISO 13849 - 1 standard, meeting the requirements of Category 3 and 4 functional safety. This enables customers to simplify their safety control systems by reducing the number of components needed. The valve's pre - certification also streamlines the integration process for manufacturers.

Compact and Efficient Design

The VPX400 is compact yet high - performance. Its strong exhaust flow ensures quick power - off, significantly reducing downtime and enhancing operational safety. The valve also features integrated soft - start functionality, preventing sudden movement of pneumatic actuators during machine startup, thereby reducing operator risks and potential machine damage.

With a modular integrated design, the VPX400 seamlessly pairs with SMC's AC - D series of air treatment equipment, minimizing assembly time and installation space. Its compatibility with other air treatment components reduces the need for additional fittings and piping, simplifying the assembly process and lowering leakage risks.

User - Friendly Features Boosting Safety

Beyond its technical advantages, the VPX400 comes with a local LED status display, providing instant and intuitive feedback on the valve's operational status. This enables quick fault identification, simplifies troubleshooting, and cuts downtime. Additionally, the VPX400's low power consumption (just 0.2 watts per internal valve channel) ensures minimal energy use, supporting cost - effectiveness and sustainability.

Built for Harsh Environments

The VPX400 boasts an IP65 protection rating, making it robust enough to handle harsh environments. It can be directly installed on machinery in dusty or damp conditions without the need for an additional housing. Moreover, the valve's M12 power connector simplifies installation, reduces wiring error risks, and saves valuable installation time.

A Comprehensive and Reliable Solution

SMC's VPX400 series safety exhaust valve is a comprehensive and reliable solution that can be seamlessly integrated with existing systems. It enhances safety and operational efficiency across a wide range of industrial applications.
