Air pump solenoid valve (380 V) — compact, reliable airflow control with exhaust check valve and quiet operation Key benefits Saves space and fits tight installations: small, lightweight design makes it easy to mount in cramped control cabinets or on compact air compressors. Reliable control for 380 V systems: rated for 380 V to provide consistent, efficient switching of air flow in industrial and commercial compressor setups. Prevents backflow and protects equipment: built‑in exhaust check valve ensures one‑way discharge, avoids pressure backflow and helps maintain steady system performance. Low noise for a better work environment: engineered for quiet operation to reduce workplace noise without sacrificing functionality. What it does and why you need it Controls the flow of compressed air in pump and compressor circuits, enabling automated on/off operation and accurate venting. Solves common installation problems by combining a compact footprint with a built‑in exhaust check valve, eliminating the need for separate backflow hardware. Ideal when you need dependable 380 V compatibility, space savings, and reduced noise—especially in workshops, production lines, and maintenance cabinets. Standout attributes Function: Solenoid‑actuated valve designed for air pump/compressor systems, with integrated exhaust check to prevent reverse flow. Compatibility: Nominal voltage 380 V for direct compatibility with standard three‑phase industrial supply. Size and installation: Compact, lightweight form factor for easy placement in limited spaces. Performance: Stable airflow control and quiet operation to minimize disruption in work areas. Typical use scenarios Small machine shops: Mounted on benchtop air compressor units where cabinet space is limited and quiet operation is preferred. Industrial pneumatic systems: Integrated into compressed air lines of production equipment that runs on 380 V supply and requires reliable anti‑backflow protection. Maintenance and service panels: Used in equipment control cabinets to manage venting and prevent pressure backflow without adding bulk or noise. Included features summary Compact, space‑saving design Rated for 380 V operation Integrated exhaust (non‑return) check valve to prevent backflow Low‑noise operation suitable for workplace environments Notes for buyers Designed specifically for air pump/air compressor applications; ensure compatibility with your system voltage and piping before installation. Compact size and integrated check valve reduce installation complexity where space and performance matter.
