Specifications Hign-concerned Chemical:None Model Number:N375 Material:Plastic Timer Type:Ac Pro Brand Name: Origin:Mainland China Type:Garden Water Timers The N375 Pulse Solenoid Valve Controller offers precise water flow control with 8 independent watering programs, low power consumption, and an IP68 waterproof rating for outdoor use. It supports various fluids, including water and non-corrosive liquids, ensuring efficient irrigation. Ideal for gardening, agriculture, and smart water management. Precise Pulse Control: The N375 pulse-type solenoid valve controller uses a timer-triggered pulse signal to precisely control water flow activation and shutdown. It supports positive pulse for opening and negative pulse for closing, with a response time of less than 0.01 seconds. This ensures efficient water conservation and accurate irrigation, making it ideal for gardening, agriculture, and industrial applications. 8 Independent Watering Programs: Supports 8 independent watering schedules, allowing flexible Start Time settings. Watering duration can be set between 1 minute and 9 hours 59 minutes, with watering frequency options ranging from 1 to 30 days. Additionally, it supports manual temporary watering (1 minute to 9 hours 59 minutes) without interfering with pre-set automatic schedules, ensuring personalized and efficient water management. Low Power Consumption: Operates on 2 or 4 AAA alkaline batteries, featuring an energy-efficient design that provides a battery life of 6 to 14 months. Equipped with high-quality electronic components, this controller ensures stable and reliable long-term operation, reducing maintenance frequency. IP68 Waterproof & Durable Materials: Constructed with reinforced nylon PA66 for the solenoid valve body and weather-resistant ABS for the timer housing, offering excellent impact resistance and corrosion protection. With an IP68 waterproof rating, this controller is suitable for outdoor and humid environments such as agricultural irrigation, garden watering, and water management systems. (Note: The internal rubber components are not resistant to highly corrosive media.) Wide Application: Available in multiple sizes to fit various pipeline specifications. Operating pressure ranges from 0.1-0.8MPa, with a medium temperature range of 1-70C (33.8-158F) and an ambient temperature range of -10 to 50C (14-122F). With a lifespan of up to 500,000 cycles, it is widely applicable for agricultural irrigation, garden sprinkler systems, smart water management, and water treatment applications.

Compatible Fluids: Water is recommended, but non-corrosive liquids, light oil (viscosity 20cst), or gases may also be used depending on the actual situation. Note: 1. Water Pressure Requirement: Do not connect to a water source without pressure, such as a ton barrel. The system is designed to operate within a pressure range of 0.1-0.8 MPa. 2. Fluid Compatibility: Water is recommended, but non-corrosive liquids, light oil (viscosity 20cst), or gases may also be used depending on the actual situation. Avoid using highly corrosive fluids to prevent damage. If using non-water-based media, performance may be affected, so please control usage accordingly. 3. Temperature Range: Use within the specified temperature range (1-70C for working temperature, -10 to 50C for ambient temperature) to prevent malfunction. 4. Maintenance: Regularly check the valve and timer to ensure proper functioning and clean as needed to avoid clogging or debris buildup.
