SMC 全新 VPX400 系列安全排气阀：提升机器安全性与运行效率
2025-11-25SMC 正式推出 VPX400 系列安全排气阀，该产品专为工业气动系统中的安全需求而设计，可在紧急停机时快速排出压缩空气，确保设备和操作人员的安全。VPX400 能够迅速清除残余气压，减少因储存的气动能量带来的潜在风险，是目前制造业安全升级中的关键组件之一。
快速排气，确保紧急停机安全
在紧急停机（E-Stop）状态下，VPX400 会立即排出阀后端（secondary side）的所有空气，确保气动设备完全失压，避免气缸或执行元件因残余压力而产生意外动作。
该系列采用 双冗余安全设计（dual redundancy）。即使在极少数情况下某一内部阀芯出现故障，另一阀仍可正常工作，大幅提升整体系统的安全可靠性。对于已经识别出“残余气压风险”的应用场景，VPX400 是理想的安全排气解决方案。
符合 ISO 13849-1 标准：安全等级达到 Category 3 与 4
VPX400 完全符合国际安全标准 ISO 13849-1，并满足 Cat.3 和 Cat.4 的功能安全等级要求。对用户而言，这意味着：
• 安全控制系统可大幅减少组件数量
• 系统架构更简单、安装更快捷
• 产品已通过预认证，整机认证流程更加顺畅
对于需要构建 CE、ISO 或其他国际安全体系的设备制造商而言，这项特性尤为重要。
紧凑、强效、可模块化组合
VPX400 虽然结构紧凑，却具备极高的排气能力，能显著提升设备的去能时间（de-energisation speed），减少停机时间并增强设备安全性。同时，阀体内置 软启动功能（soft start-up），在机器启动初期逐渐向系统供气，防止气缸或执行器突然动作造成风险或设备损坏。
更值得一提的是，该系列专为模块化集成而生，可与 SMC AC-D 系列空气处理单元 无缝连接，减少安装空间与组装时间。配套组件减少后，接头与管路数量大幅下降，从而降低泄漏隐患。
用户友好设计：LED 状态指示与超低功耗
VPX400 配备 本地 LED 状态指示灯，可即时显示阀门工作状态，让维护人员快速定位故障点，从而缩短停机时间。此外，其每个内部阀芯仅消耗 0.2W 超低功耗，在保证性能的同时进一步提升能源效率，符合可持续运营的趋势。
适用于严苛工业环境：IP65 防护等级
VPX400 具备 IP65 防护等级，可在粉尘、潮湿等严苛环境中稳定工作。产品可直接安装在设备上，无需额外防护盒。
同时，标准化 M12 电源连接器 让布线更简单，能够有效避免接线错误，减少安装时间与成本。
适用范围广泛的一体化安全排气解决方案
SMC VPX400 系列安全排气阀是气动系统安全升级的全方位解决方案，可与现有系统轻松集成，为工业设备带来更高的安全性与运行效率。

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.
