Description
RPE NBWL12V — 9/12V DC Bistable Irrigation Solenoid Valve — NC — 3/4'' or 1'' F/F — 0.5-10 bar — Battery Systems and Controllers
The RPE 9/12V DC bistable (latch) solenoid valve is designed for automatic irrigation systems powered by battery-powered controllers and 9/12V DC systems. Available in 3/4'' and 1'' female GAS, with a PA66 polyamide body reinforced with 30% glass fiber and reinforced threading, and an NBR diaphragm. Normally Closed (NC) operation, operating pressure 0.5-10 bar, and fluid temperature up to 60°C. The bistable (latch) technology consumes power only during opening/closing, maintaining its position without continuous power — ideal for maximizing battery life in controllers. Made in Italy — RPE S.r.l.
- Bistable (Latch) 9/12V DC — consumes power only during switching, not continuously
- Maximum battery life — ideal for battery-powered controllers with multiple zones
- 2 variants — 3/4'' F/F (SKU 702702L) and 1'' F/F (SKU 702703L)
- Normally Closed (NC) — closed without power, safety in case of a dead battery
- Pressure 0.5-10 bar — compatible with standard water network systems
- PA66 body + 30% glass fiber — high mechanical and weather resistance
- Reinforced threading — superior resistance to mechanical stress
- NBR diaphragm — reliable sealing and long-lasting durability
- Fluid temperature up to 60°C
- Made in Italy — RPE S.r.l.
Bistable (Latch) — how it works and why it extends battery life
- Standard monostable valve: requires continuous power to keep the valve open. Consumes power throughout the entire irrigation cycle. With battery-powered controllers, this significantly reduces battery life
- Bistable valve (this one): consumes power only for a very brief pulse during opening and another during closing. Between the two pulses, it consumes no power. The valve maintains its position (open or closed) without power
- Practical advantage: with a battery-powered controller managing 6 zones for 20 minutes a day, a bistable valve consumes 99% less power than a monostable valve, extending the controller's battery life from weeks to months or years
- Compatibility: check that the controller supports bistable (latch) valves and that the output is 9V or 12V DC. Mid-range and high-end battery-powered controllers (Hunter, Rain Bird, Orbit, Claber, etc.) generally support bistable valves
Available variants
| Variant | SKU | Thread |
| 3/4'' Female GAS | 702702L | 3/4'' F/F |
| 1'' Female GAS | 702703L | 1'' F/F |
Main features
- PA66 body with 30% glass fiber: reinforced polyamide for high mechanical, impact, and weather resistance. Suitable for outdoor installation with temperature fluctuations
- Reinforced threading: superior resistance to mechanical stress during installation and use, reducing the risk of thread breakage compared to standard plastic bodies
- NBR diaphragm: elastomer resistant to water, oils, and compatible chemicals. Ensures reliable sealing over time even with pressure fluctuations
- Normally Closed (NC): in case of a dead battery or controller failure, the valve remains closed, preventing uncontrolled irrigation
- Pressure 0.5-10 bar: compatible with standard water network pressure (typically 2-6 bar in Italy)

Frequently Asked Questions (FAQ)
Q: How do I check if my controller is compatible with bistable valves?
A: The controller must support bistable (latch) valves and have 9V or 12V DC outputs. Check the controller specifications or contact the manufacturer. Mid-range and high-end battery-powered controllers (Hunter Node, Rain Bird TBOS, Orbit B-hyve, etc.) generally support bistable valves. 24V AC controllers are not compatible with this valve.
Q: What is the difference between this valve and the 24V AC versions?
A: The 24V AC versions use a monostable coil that requires continuous power to keep the valve open — not compatible with 9/12V DC battery-powered controllers. This bistable version consumes power only during switching and is designed specifically for 9/12V DC battery-powered controllers.
Q: Which variant should I choose between 3/4'' and 1''?
A: The choice depends on the diameter of the system's main pipe. 3/4'' (DN 20mm) is suitable for domestic systems with moderate flow rates. 1'' (DN 25mm) is suitable for systems with higher flow rates or 1-inch main pipes. If in doubt, choose the size corresponding to the diameter of the main pipe.
Q: Can I use it with well water or non-potable water?
A: Yes, the NBR diaphragm and PA66 body are compatible with well water and non-potable water with moderate mineral content. Install an upstream filter to protect the diaphragm from impurities and sand.
