Rain Bird 100-HV 1″ BSP High-Performance Compact Solenoid Valve with Flow Control (24 VAC)
The Rain Bird 100-HV with Flow Control represents the next generation of irrigation management, offering a highly reliable, exceptionally compact solution for residential and light commercial watering systems. Engineered for tight spaces, this 24 VAC mains-powered valve delivers industrial-grade performance. Featuring an integrated flow control mechanism, it allows professional installers across Europe to precisely calibrate water volume to match exact zone requirements.
Advanced Engineering & Reliability
- Integrated Flow Control: Equipped with a unique, easy-to-turn, pressure-assisted flow control mechanism that allows precise adjustment of water flow, optimizing sprinkler performance and efficiency.
- Compact Spin Radius: Features an ultra-compact 2.54″ (6.5 cm) spin radius, allowing multiple valves to be installed closer together in smaller valve boxes for clean, space-efficient manifold layouts.
- Glass-Filled Polypropylene Body: Moulded from premium, glass-filled polypropylene to ensure unmatched structural strength, high pressure resistance, and long-term durability against environmental stress.
- Eccentric Diaphragm Design: Incorporates a specialized eccentric diaphragm that guarantees smooth, progressive closing. This innovative design significantly minimises water hammer, protecting your pipework from destructive pressure surges.
- Dual Bleed Functionality: Equipped with an external bleed screw for quick, manual system flushing during commissioning, and an internal bleed for clean, spray-free manual operation directly from the valve box.
- Installer-Friendly Maintenance: Designed with a captive multi-drive screw bonnet and a smart solenoid coil that prevents the plunger and internal spring from falling out, ensuring hassle-free servicing in the field.

Versatile Integration
The Rain Bird 100-HV 24 VAC valve seamlessly integrates with all automated irrigation controllers and rain sensors. Whether managing precise drip zones, micro-sprinklers, or high-pressure pop-up lawn zonation, the HV series offers maintenance-free water management. Its robust, reverse-flow design ensures the valve remains securely closed in the event of power loss, safeguarding your property against potential water wastage.
Note: For ultra-low flow applications below 0.68 m³/h (3 GPM), the installation of a Rain Bird filtration system upstream is highly recommended.
