The Hunter ICV 1" AC Valve with Flow Control brings true commercial-grade power to standard 1-inch irrigation manifolds. Engineered from high-strength, glass-filled nylon rather than standard PVC, this valve is designed to withstand punishing pressure spikes up to 220 PSI that would easily shatter standard residential equipment.
Inside, the ICV utilizes a rugged, fabric-reinforced EPDM diaphragm and seat. This specialized internal construction ensures flawless performance and resists wear and tear even when processing dirty, sandy, or reclaimed water. When wired to a standard AC Irrigation Controller, the built-in flow control handle allows you to precisely dial down pressure and output, making it an incredibly versatile, fail-safe choice for demanding landscape and agricultural zones.

Follow these steps to safely plumb and wire your Hunter ICV valve.
Step 1: Plumb the Connections
Using high-quality Teflon tape, thread 1" male PVC adapters into the inlet and outlet ports. Ensure the directional arrows on the valve body perfectly align with the direction of your water flow.
Step 2: Install in a Valve Box
Seat the fully plumbed valve inside an underground rectangular valve box over a deep bed of gravel to ensure proper drainage and protection from freezing.
Step 3: Connect the Wiring
Connect one wire from the 24V solenoid to your controller's common wire, and the other solenoid wire to the specific station/zone wire. Securely seal all connections using waterproof wire nuts.
Step 4: Adjust the Flow
Turn on your main water source and activate the zone manually. Rotate the top flow control handle to dial in the perfect operating pressure and volume for your downstream emitters.
What makes the 1" Hunter ICV different from standard residential valves?
The 1-inch ICV is built from heavy-duty glass-filled nylon rather than standard PVC. This allows it to easily handle extreme pressure spikes up to 220 PSI, preventing the cracking commonly seen in residential valves.
Can I use the Hunter ICV valve with dirty or reclaimed water?
Yes, the Hunter ICV is highly capable of handling challenging water sources. Its fabric-reinforced EPDM diaphragm and robust seat are specifically engineered to resist wear and maintain reliable performance in dirty or reclaimed water systems.
Does this valve require a special commercial controller?
No special commercial timer is required. It includes a standard 24-volt AC solenoid, meaning it is completely compatible with any standard hardwired indoor or outdoor AC irrigation controller on the market.
How do I manually turn on the Hunter ICV valve in the field?
You can easily activate the valve directly at the box using either the internal or external manual bleed screw. This allows for quick line flushing and maintenance without needing to walk back to the controller.
Why is mid-May a good time to upgrade my 1" valves to the commercial-grade ICV?
Mid-May is the ideal time to replace any standard valves weakened by winter freezes. Upgrading to the shatter-resistant ICV model now ensures your system can handle the constant pressure of your impending summer watering schedule.
Discovering a hairline fracture in a standard PVC valve during peak July heat can lead to massive water loss. Upgrading your manifolds to glass-filled nylon in the spring guarantees high-pressure reliability all season long.
