【English Version】
The SR551-RN2※R series is a 5-port 2-position sliding spool solenoid-controlled directional valve specifically engineered for industrial automation control systems. Combining electromagnetic actuation with a spool-type mechanism, this valve provides precise flow path control for pneumatic transmission systems. The electromagnetic coil drives spool position switching through electrical energization/de-energization, delivering rapid response and reliable operation to meet demanding directional switching requirements in automated equipment.
Featuring a modular construction, the valve body is manufactured from high-strength aluminum alloy. The precision-machined spool assembly works in conjunction with high-accuracy guiding structures to minimize friction resistance, ensuring consistent sealing performance even under prolonged high-frequency operation. Dual solenoid configuration supports both monostable and bistable control modes, offering flexible control strategy selection. Standard port dimensions comply with common industrial pneumatic component specifications, compatible with ISO 15218 or DIN port connection standards for easy integration into existing pneumatic circuits.
Operational parameters include working pressure range of 0.15-0.8MPa, compatible with filtered compressed air (≥40μm filtration), and ambient temperature tolerance from -5℃ to +60℃. The solenoid coil boasts IP65 protection rating for effective dust and water resistance. Anodized surface treatment enhances corrosion resistance. Multiple voltage options (DC12V/24V, AC110V/220V) are available to accommodate regional electrical standards.
Typical applications encompass: mold clamping control in injection molding machines, actuator drive systems for packaging machinery, and pneumatic fixture operation in automated assembly lines requiring bidirectional pneumatic control. By precisely regulating cylinder reciprocating movements, this valve contributes to improved operational efficiency. Regular inspection of seal conditions and maintenance of air source cleanliness are recommended to ensure long-term operational stability.
