SMC has introduced the VPX400 Series Safety Exhaust Valve, aimed at enabling a rapid release of air while promoting enhanced safety in industrial pneumatic systems. Designed for emergency stop situations, the VPX400 ensures rapid elimination of residual air, reducing hazards linked to stored pneumatic energy and enhancing operator safety.
During emergency stop scenarios, the VPX400 quickly releases air from the valve’s secondary side, guaranteeing that pneumatic energy is securely eliminated from attached devices. The dual redundancy system of the valve guarantees ongoing operation, even if one valve fails, making it a dependable safety measure in situations where risks from residual air pressure have been recognized.
The VPX400 adheres completely to ISO 13849-1, fulfilling the requirements of Categories 3 and 4 for functional safety. This enables clients to streamline their safety control systems by minimizing the number of required components. The valve is pre-approved, simplifying the integration process for producers.
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.
