Product Overview
The SR351-RN2※DL is a 3-position, 2-way solenoid-controlled spool-type directional valve, designed for precise fluid control in industrial automation systems. Its spool mechanism ensures rapid response and reliable switching performance, making it suitable for applications requiring high-speed actuation and durability. With a compact width of 22mm, this valve facilitates space-saving integration into modular control units, supporting both threaded and manifold-mounted installations.
Featuring a low-pressure-loss flow path, the valve optimizes medium (e.g., clean compressed air) delivery efficiency. The spool structure is engineered for reduced wear and enhanced sealing, ensuring consistent operation over extended periods. Constructed from alloy steel, the valve body provides robust resistance to corrosion and mechanical stress. Multiple wiring options (e.g., DIN or screw terminals) are available to accommodate diverse electrical configurations. The design prioritizes ease of maintenance and adaptability to varying environmental conditions.722
功能特点
该阀支持单电控模式，通过电磁线圈驱动实现气路通断切换，功耗低且无需额外润滑。其“二位三通”功能可灵活控制介质的流向，满足常开或常闭回路需求。产品内置手动紧急操作功能（按压式自锁），在断电或调试时仍可手动切换阀位，保障系统应急操作的可靠性。此外，阀体采用模块化设计，便于与其他同系列阀组组合使用，扩展多通道控制功能。
适用温度范围广，环境及介质温度适应性良好，确保在低温或高温工况下稳定运行。阀芯动作时间≤0.03秒，适用于高频次切换场景。特殊设计的密封件能有效防止杂质侵入，延长使用寿命。1430
Functional Features
The valve operates in single-solenoid control mode, enabling energy-efficient and lubrication-free switching. Its "3-position, 2-way" function allows flexible flow direction control for normally open or closed circuits. An integrated manual override (push-to-lock mechanism) ensures emergency operation during power failures or maintenance. The modular design supports seamless combination with other valves in the SR350/351 series for multi-channel systems.
Wide temperature tolerance ensures stable performance in extreme conditions, with a rapid spool response time (≤0.03s) for high-frequency applications. Dedicated sealing components prevent contaminant ingress, enhancing longevity. The valve’s compatibility with diverse industrial media and compact footprint makes it ideal for space-constrained installations.1526
应用场景
SR351-RN2※DL广泛应用于食品医药、电子制造、包装机械等行业的气动控制系统，特别适用于洁净室设备、自动化装配线及精密仪器供气系统。在需要防污染的领域（如医疗设备气路控制），其无油设计可避免介质污染风险。此外，该阀也常见于纺织机械、印刷设备等中低压气动回路中，作为核心换向元件提升系统响应速度与控制精度。
典型用例包括：气缸方向控制、真空吸附系统切换、气动夹具动作序列管理等。其轻量化和小体积特性尤其适合移动式设备或分布式控制模块。1828
Applications
The valve is widely adopted in pneumatic systems for industries such as food processing, pharmaceuticals, electronics, and packaging, particularly in cleanroom environments and automated production lines. Its oil-free design eliminates contamination risks in sensitive applications like medical gas control. It also serves as a key component in textile machinery, printing equipment, and other low-to-medium-pressure pneumatic circuits requiring fast response and accuracy.
Typical use cases include cylinder directional control, vacuum system switching, and pneumatic gripper sequencing. Its lightweight and compact form factor make it ideal for portable devices or decentralized control modules.1921
