Brand: Hunter Industries SKU: ICV-101G-FS Product Overview The Hunter ICV-101G-FS is a 1-inch commercial globe irrigation valve with flow control and a factory-installed Filter Sentry mechanism. It is designed for demanding residential, commercial, municipal, and dirty-water irrigation applications where pressure, flow variation, or suspended debris can make valve performance and service access especially important. The female-threaded globe body uses glass-filled nylon construction, a fabric-reinforced EPDM diaphragm and seat, and Hunter’s double-beaded diaphragm seal design. The 1-inch ICV platform is rated for a flow range of approximately 0.1 to 40 GPM and a recommended pressure range of 20 to 220 PSI. The broad low-flow capability allows the valve to serve compatible drip and micro-irrigation zones as well as conventional sprinkler circuits, provided the complete system is designed for the selected flow. A standard encapsulated 24 VAC solenoid with captive plunger operates the valve from a compatible irrigation controller. Filter Sentry uses a wiping mechanism to help clean the valve’s filter screen as the valve operates, reducing debris buildup in challenging water conditions. External and internal manual bleed options permit field activation, while captive bonnet screws and multi-tool screw heads support service without loose hardware. The flow-control stem allows the outlet flow to be adjusted for zone balancing or controlled shutoff during maintenance. Key Features 1-inch female NPT globe valve Factory-installed Filter Sentry mechanism Integrated flow control Approximate flow range of 0.1 to 40 GPM Recommended pressure range of 20 to 220 PSI Temperature rating up to 150°F Glass-filled nylon construction Fabric-reinforced EPDM diaphragm and seat External and internal manual bleed Standard encapsulated 24 VAC solenoid Common Uses Commercial and municipal sprinkler zones Dirty-water or pond-fed irrigation systems Reclaimed-water projects when properly identified and configured Low-flow drip or micro-irrigation zones within the published range Compatibility and Installation Notes Connect to compatible 1-inch female NPT piping. Install with the flow-direction arrow aligned with system flow. Use with a compatible 24 VAC irrigation controller unless the solenoid is replaced with an approved DC-latching option. Size the valve based on actual design flow and acceptable pressure loss, not pipe size alone. Flush the line before installation and provide service access in the valve box. Follow Hunter requirements for manual bleed, flow-control adjustment, solenoid wiring, and winterization. Frequently Asked Questions What does FS mean in the model number? FS indicates that the valve includes Hunter’s Filter Sentry mechanism for helping clean the internal filter screen in debris-prone water conditions. Can this valve be used with a battery controller? The standard valve includes a 24 VAC solenoid. Battery-operated systems require the compatible Hunter DC-latching solenoid configuration. Is 40 GPM the correct design flow for every installation? No. It is the published upper flow limit. The appropriate design flow depends on pressure loss, pipe sizing, velocity, zone demand, and system requirements. Why Buy from Big Frog Supply?
