DIG ECO1ILV.075 Solar Irrigation Controller
The DIG ECO1ILV.075 is a single-station solar powered irrigation controller designed to operate without AC power or batteries. It runs on solar energy and is built for outdoor weather resilience with IP68 waterproofing, making it a suitable choice for drip and sprinkler setups. It supports customizable schedules with up to five start times per day and watering durations up to 5 hours and 59 minutes. Its inline 3/4″ FNPT valve connection supports universal installation, enabling seamless integration into existing irrigation lines.
QiXin Automatic Water Level Control Valve (1/2″ Side Entry)
The QiXin automatic water level control valve operates without electricity, using a buoyant float mechanism to regulate water flow. Constructed with nylon PA66 and stainless steel components, it offers robust performance and corrosion resistance. The valve features a 1/2″ side entry with compatibility for 0.02-1.0 MPa pressure ranges and 1-30 L/min flow, making it versatile for water towers, solar storage tanks, ponds, and livestock troughs. It provides automatic shutoff at a preset water level, supporting efficient water management in off-grid or solar-powered setups.
PNXKTXO 2 Pack Automatic Water Level Control Valve
The PNXKTXO 2-pack provides automatic water level control valves designed for solar powered or general water management needs. Each valve is designed for compatibility with various plumbing systems and includes stainless steel screws and a rust-resistant build. The unit stops water flow when water reaches a defined level and resumes as levels drop, enabling efficient water usage in tanks, pools, and solar storage. The two-pack option helps manage multiple tanks or pools concurrently, increasing value for larger setups.
BesNPT Solenoid Valve for Solar Water Heater
The BesNPT solenoid valve is a 3/4″ G thread, DC 12V valve intended for solar water heater applications. Made with plastic and brass components, it is designed for durable, long-term use in solar-powered systems. The valve provides straightforward on/off control suitable for solar heating lines, enabling efficient, electricity-free water control in solar installations while maintaining dependable operation under typical residential or light-commercial use.
Sloan SOLIS 8111 – Solar Flushometer
The Sloan SOLIS 8111 is a solar-powered, exposed sensor flushometer designed for high-traffic restrooms. It uses photovoltaic energy to power a sensor-based flush mechanism, offering a hygienic, hands-free operation. The unit supports infrared sensing with a courtesy flush override, suitable for commercial and institutional environments aiming to reduce water waste while leveraging solar energy for operation.
Yosoo Health Gear Normally Closed Electric Water Shut Off Valve
This normally closed solenoid valve is a 3/4″ DC 12V unit designed for reliable water control in powered systems. The valve features a 0.02-0.8 MPa pressure range and a 300 mA rated current, supporting stable performance in water pipelines. While not exclusively solar-powered, it can be driven in solar-assisted configurations where a low-voltage source is available, offering precise on/off control for irrigation and potable water lines.
Buying Guide: Key Considerations For Selecting Solar Powered Water Valves
When selecting a solar powered water valve, consider how the valve will be used, the installation environment, and the available power source. The following factors help compare options and ensure reliable performance across different setups.
- Power source and energy management: Prioritize valves with built-in solar compatibility or minimal power requirements. For off-grid or solar-only installations, IP-rated durability and battery-free operation are crucial.
- Flow control and pressure range: Verify flow rates and pressure ranges match your system requirements. For irrigation or livestock water, higher flow and stable duty cycles are beneficial, while precision shutoffs excel in tanks and storage.
- Installation compatibility: Check thread sizes (1/2″, 3/4″ NPT/G threads) and entry directions (top or side) to ensure seamless integration with existing piping.
- Materials and durability: Stainless steel components resist corrosion in water environments, while robust plastics or brass offer dependable longevity in solar installations exposed to the elements.
- Control features: Some valves offer programmable schedules, multiple start times, or sensor-based operation. Choose features that align with your irrigation schedule or automatic level monitoring needs.
- Maintenance and seals: Look for valves with strong seals, proper gaskets, and corrosion-resistant screws. Proper installation techniques reduce leakage and extend service life.
- Applications: Distinguish between irrigation controllers, water level sensors, and flushometers. Solar powered models span residential, agricultural, and commercial use-cases; select the one that best fits your scenario.
