New SMC VPX400 Series Safety Exhaust Valve Enhances Machine Safety and Efficiency
SMC has launched the VPX400 Series Safety Exhaust Valve, designed to provide a quick exhaust of air and ensure superior safety in industrial pneumatic systems. Ideal for emergency stop scenarios, the VPX400 offers quick removal of residual air, mitigating the risks associated with stored pneumatic energy and improving safety for operators.
In emergency stop situations, the VPX400 rapidly exhausts air from the secondary side of the valve, ensuring that pneumatic energy is safely removed from connected equipment. The valve’s dual redundancy system ensures continued functionality, in the unlikely event that one valve fails, making it a reliable safety solution in applications where risks from residual air pressure have been identified.
The VPX400 is fully compliant with ISO 13849-1, meeting Category 3 and 4 requirements for functional safety. This allows customers to simplify their safety control systems by reducing the number of components needed. The valve is pre-certified, streamlining the integration process for manufacturers.
Compact, Efficient, and Modular
Despite its small footprint, the VPX400 delivers impressive performance. Its large exhaust flow capacity ensures rapid de-energisation, significantly reducing downtime and improving operational safety. The valve also integrates a soft start-up function, preventing sudden pneumatic actuator movements when machines are initially started, reducing the risk to operators or damage to machinery.
Designed for modular integration, the VPX400 pairs seamlessly with SMC’s AC-D Series air preparation equipment, minimising assembly time and installation space. The valve’s compatibility with other air preparation components reduces the need for additional fittings and tubing, streamlining the assembly process and reducing the potential for leaks.
User-Friendly Features for Enhanced Safety
In addition to its technical advantages, the VPX400 is equipped with a local LED status display, providing immediate visual feedback on the valve’s operational status. This enables quick identification of faults, simplifying troubleshooting and reducing downtime. Furthermore, the VPX400’s low power consumption (just 0.2 Watts per internal valve channel) ensures minimal energy use, supporting both cost-efficiency and sustainability efforts.
Designed for Harsh Environments
With up to IP65 protection, the VPX400 is built to withstand demanding environments. Whether in dusty or wet conditions, the valve is durable enough to be mounted directly onto machinery, eliminating the need for additional enclosures. Additionally, the valve’s M12 power connector simplifies installation, reducing the risk of wiring errors and saving valuable installation time.
The VPX400 Series Safety Exhaust Valve from SMC is a comprehensive, reliable solution that integrates seamlessly with existing systems, enhancing both safety and operational efficiency across a wide range of industrial applications.
