Rain Bird Replacement Solenoid for CP/CPF Series
Brand: Rain Bird. Model compatibility: CP and CPF series valves, including APAS, ASVF, ECV, and DAS series. Features include energy-efficient, low-power encapsulated solenoid with a captured plunger for long life and dependable operation. Best for owners of Rain Bird CP/CPF valves seeking a direct replacement that minimizes energy use. A potential limitation is that this solenoid is designed specifically for Rain Bird valves, so compatibility with other brands may be limited.
Hunter PGV 1″ Sprinkler Valve
Brand: Hunter. Type: 1″ inline valve with flow control, 24V AC solenoid, and heavy-duty diaphragm designed for lawn, garden, or commercial use. Best for larger zones or systems requiring precise flow management to prevent overwatering. The included 24V AC solenoid ensures compatibility with standard irrigation timers. A limitation could be that it requires compatible sizing and threading in your existing PVC setup.
Lisnhlin 236239 SOLASSG4 Solenoid Repair Kit
Brand: Lisnhlin. Purpose: Replacement repair kit for several valve models, including PEB, PGA, EFB-CP, BPE/BPES, and GB valves. Best for DIY repairs where restoring valve performance quickly matters. The kit aims to restore reliable water flow control and prevent wastage. Caution: verify model compatibility as listed models vary; not all kits cover every valve in your system.
Orbit 57623 Anti-Siphon Valve
Brand: Orbit. Type: 3/4″ FPT anti-siphon valve with flow control and atmospheric vacuum breaker. Best for preventing backflow and contamination in systems lacking a separate backflow preventer. Suitable for above-ground installations on risers with an integrated scrubber filter. Limitation: anti-siphon valves can be more expensive and larger than standard valves.
Irritrol R811-24VACG Solenoid (2 Pack)
Brand: Irritrol. Features captive hex plunger and male thread for easy installation. Operates at 24VAC with a 40 amp inrush and 20 amp holding. Best for systems that require reliable, robust 24V actuators and straightforward installation. A potential limitation is that some installations may need larger inrush current management depending on the controller and wire gauge.
Mysora 24VAC Solenoid Replacement
Brand: Mysora. Type: 24VAC solenoid replacement with 3/4″ MPT and plunger-seat assembly. Best for residential and commercial irrigation valves that require a complete plunger-seat replacement for precise actuation. The kit notes compatibility with Irritrol 2400/2500/2600/700 and Toro EZ-Flo Plus models. Limitation: ensure exact thread sizing and seat compatibility with your valve to avoid leaks or misalignment.
Buying Guide
What should you consider when choosing a solenoid?
- Voltage compatibility: Most irrigation systems use 24VAC. Verify your controller’s voltage before selecting a solenoid.
- Valve compatibility: Solenoids are often model- and brand-specific. Check the valve’s model number and thread size (NPT or BSP) to ensure a proper fit.
- Power consumption: Energy-efficient solenoids reduce standby power and heat. This matters for systems with many zones or difficult-to-access valves.
- Installation ease: Some solenoids come as complete repair kits with plungers and seats, while others are direct replacements. Choose based on your comfort with installation tools.
- Durability and materials: Encapsulated or sealed solenoids resist moisture and debris, extending life in outdoor environments.
- Backflow considerations: For systems in areas with water quality concerns, anti-siphon or backflow-preventing options can be important for safety and code compliance.
Frequently Asked Questions
- What voltage do irrigation solenoids typically use?
Most solenoids operate at 24V AC, which is standard for irrigation controllers.
- Can I reuse the same solenoid on a different valve brand?
Compatibility depends on thread size and valve type. Check model numbers and valve manuals before swapping.
- What is a captive hex plunger?
A captive hex plunger helps ensure a secure fit and reliable actuation during operation, reducing wear.
- Should I replace a solenoid with a repair kit or a full solenoid?
Use a repair kit for a specific failed component (like the plunger or seat). Replace the entire solenoid if the coil or housing is damaged.
- What is backflow prevention, and why is it important?
Backflow prevention stops contaminated water from entering the potable supply, protecting health and meeting code requirements.
- How do I verify compatibility with 1″ or 3/4″ valves?
Measure the valve’s inlet/outlet thread size and confirm with the product’s specifications before purchasing.
