Hunter PGV 1½ Inch Irrigation Valve with Flow Control
The Hunter PGV 1½ Inch Valve features a flexible globe/angle configuration, enabling retrofits and layouts that require either orientation. Integrated flow control helps fine-tune water output to match zone needs, improving efficiency. The bonnet design uses captive screws compatible with flathead, Phillips, or nut drivers, simplifying maintenance and reducing lost parts.
Best for: installations needing layout flexibility and precise flow management in mid-sized zones. Limitations: do-it-yourself service may be hindered by limited access in tight valve boxes.
Hunter Sprinkler PGV151 PGV Series 1-1/2″ Globe Or Angle Valve
The PGV151 builds on Hunter’s reliability with both globe and angle compatibility and a dedicated flow control option. It includes external and internal manual bleed for quick valve activation and a double-beaded diaphragm seal for leak-free performance. It supports low-flow systems, making it compatible with micro-irrigation products in larger landscapes.
Best for: larger landscapes needing robust leak protection and optional low-flow operation. Caution: higher-flow systems may require professional sizing to avoid performance gaps.
FIMCO 1½ Inch In-Line Electric Solenoid Valve
This in-line valve uses a 24VAC coil and a manual rotary switch for added convenience. It employs 1½” NPT threaded inlets and outlets, and the housing is crafted from glass-filled nylon for durability and UV resistance. It’s a solid choice for retrofit projects that require reliable electric actuation and flow control in exposed or semi-exposed environments.
Best for: installations needing electric operation and robust UV resistance. Choose this if you want a straightforward retrofit with strong material durability. Limitation: service accessibility can affect maintenance speed in compact boxes.
K-Rain 7115 Pro 1½” Electric Valve
With pro-grade construction and a removable metering pin, the 7115 Pro offers precise control and easy maintenance. Its UV and corrosion resistance ensures lasting performance in challenging outdoor conditions. The valve supports manual operation for bypass workflows and quick testing of zones.
Best for: professional irrigation installs needing durable, service-friendly components. Be aware: some users may prefer additional flow-control options depending on system size.
Rain Bird PESB Inline Valve with Scrubber
The PESB inline valve combines a 1½ inch FPT design with a bonnet that can be attached or removed easily to prevent thread damage during servicing. The included nylon scrubber works with a stainless steel screen to minimize grit reaching the valve internals, helping maintain reliable operation in debris-prone environments.
Best for: systems needing debris management and easy bonnet handling. Limitation: plastic construction may be less durable in extremely exposed, high-traffic areas compared to metal-bodied models.
Buying Guide
Key considerations when choosing a 1.5 inch sprinkler valve include configuration flexibility, flow control needs, and installation environment.
- Configuration: If your layout includes both globe and angle sections, prioritize models that support both configurations without extra adapters.
- Flow control vs. fixed flow: Choose valves with integrated flow control for fine-tuning zones or pick fixed-flow models when you want simple, reliable actuation.
- Electric vs. manual: Electric solenoid valves enable automated irrigation cycles, while manual bleed or switch models are useful for testing and bypass scenarios.
- Durability and materials: Glass-filled nylon and UV-resistant housings are common for outdoor use; metal components may offer higher long-term durability.
- Maintenance access: Bonnet design, screws, and service interfaces affect how easy it is to service the valve in a buried or tight installation.
- Debris management: Valves with built-in scrubbers or compatible screens help protect operation in areas with sediment or vegetation debris.
- System size and compatibility: Ensure inlet/outlet sizes and thread standards (NPT vs. FPT) align with existing piping and fittings in your irrigation system.
