DC 5V / 6V Electric Mini N/C Solenoid Valve — compact, reliable control for water, air and gas applications This mini 2position, 2way electromagnetic solenoid valve is designed as a normally closed (N/C) release and exhaust valve for small systems. It operates on DC 5V or DC 6V power and is ideal when you need compact, lowvoltage control of fluid or gas flow — for example, to control air pump exhaust or to release water, air or gas in small devices. Key benefits Precise on/off control: Normally closed operation stays locked when unpowered and opens when energized, giving simple, predictable control of flow or exhaust. Lowvoltage operation: Runs on common DC 5V or 6V supplies, making it easy to integrate with small electronic controllers, battery systems and hobby electronics. Compact and easy to install: Mini size fits tight spaces and small assemblies where a fullsize valve would be impractical. Versatile media compatibility: Designed for use with water, air and gas, making it suitable for a variety of small fluid and pneumatic tasks. Key attributes Type: N/C (normally closed) solenoid valve. Actuation: Electromagnetic (electric mini solenoid). Positions/Ways: 2position, 2way (simple open/closed flow control between two ports). Voltage: DC 5V or DC 6V operation. Intended uses: Water, air and gas release/exhaust control; specifically referenced for air pump applications. Form factor: Mini / compact design for tight installations. How it solves common problems Eliminates manual venting: Automatically release or exhaust air/gas when triggered, removing the need for manual intervention. Fits small systems: Compact design enables automated control in hobby projects, small pumps and compact equipment without redesigning for space. Simplifies lowvoltage integration: Operates on widely available DC voltages so you can control it with microcontrollers, small relays or batterypowered systems. Typical applications Air pump exhaust control: Automate venting or release functions on small air pumps used in aquariums, inflatables or pneumatic hobby projects. Small fluid or gas release systems: Control the release or exhaust of water, air or inert gases in laboratory setups, small appliances or model equipment. Pneumatic actuators and hobby projects: Integrate into miniature pneumatic circuits for quick on/off control of airflow. Installation and use notes Designed for DC 5V or DC 6V supply; ensure correct voltage selection for your system. Intended for control of water, air and gas in smallscale applications — confirm compatibility with your specific fluid or gas before use. As a normally closed valve, it remains closed without power and opens when energized; plan wiring and control signals accordingly. This mini 2position, 2way electromagnetic solenoid valve provides straightforward, lowvoltage control of water, air and gas release or exhaust. Its normally closed design and compact size make it a practical choice for air pump systems and other small automated fluid or gas control tasks.
