Fimco 1 ½” In 4 Outlet Indexing Valve
The FIMCO valve features a 1 inlet with four slip-fit outlets designed for 1-1/2″ pipe. It supports 2-, 3-, and 4-zone indexing via cam configurations. Valve sizing is critical: confirm the correct inlet/outlet size for your installation, as pipe size is determined by inside diameter. This model provides indexing options with flexible zone control, suited for mid-to-large residential systems requiring multi-zone distribution.
K Rain 4404 Indexing Valve
The K-Rain 4404 indexing valve offers a high-impact ABS polymer body for durability and long service life. Available in 4- and 6-outlet configurations, it allows quick reconfiguration from two to six watering zones. The design emphasizes simplicity of maintenance and servicing, enabling straightforward field repairs and reliable operation in standard sprinkler systems.
Hunter PGV 1″ Sprinkler Valve
The Hunter PGV valve includes built-in flow control for precise zone management. It features 1″ NPT female threading for easy compatibility with typical PVC setups, making it suitable for both new installations and replacements. A 24V AC solenoid is pre-installed and works with major irrigation timers to enable seamless automated watering across multiple zones.
Rain Bird DASASVF100 Anti-Siphon Valve
Professional-grade anti-siphon valve with flow control, designed for above-ground installation. It prevents backflow when placed 6 inches above the highest sprinkler head and can operate automatically or manually via a bleed screw. This valve is ideal for systems needing robust backflow protection while maintaining simple operation and manual override options.
Orbit 57624 1-Inch FPT 100 Series Valve
This Orbit valve is designed for drip and small sprinkler zones, featuring a 1″ FPT connection and an integrated 120-mesh stainless steel filter with a top flush port for easy cleaning. It includes a 24 VAC solenoid, a manual actuation lever, and a bleed screw for manual control and maintenance, making it a practical choice for compact or drip-focused irrigation layouts.
Rain Bird CP100 In-Line Automatic Valve
The Rain Bird CP100 provides residential or light commercial grade 1″ threaded female inlet and outlet connections. It’s designed for below-ground installation and works with standard sprinkler timers. The compact, in-line design helps conceal the valve while delivering reliable automation and water flow control across zones.
Buying Guide: Key Purchase Considerations
- Size and compatibility: Confirm inlet/outlet sizes and thread types (1″ vs 1-1/2″ vs 1-1/4″ where applicable). The wrong size can restrict flow or prevent installation.
- Valve type and function: Anti-siphon vs inline; indexing valves for multi-zone control; consider whether you need built-in flow control, manual bleed screws, or integrated filters.
- Flow and pressure ratings: Ensure the valve supports your system’s flow requirements and water pressure. Some valves are optimized for drip or landscape irrigation, while others handle larger zones.
- Electrical compatibility: If using solenoids, verify voltage (24V AC is common) and compatibility with your irrigation timer or controller.
- Installation location: Above-ground anti-siphon valves simplify access and installation, but below-ground installations offer a neater appearance and reduced weather exposure.
- Maintenance needs: Look for valves with accessible seals, easy disassembly for service, and built-in filters when dealing with sediment-prone water.
- Durability and material: Polypropylene/ABS bodies offer corrosion resistance; metal components may provide higher durability in heavy-use systems.
- Future expansion: If you anticipate adding zones, choose valves with modular or easily upgradable indexing or multi-outlet designs to minimize replacement.
