The Irritrol 700-1 1" UltraFlow 700 Series Valve is a rugged, highly efficient irrigation valve engineered to solve one of the most common system problems: pressure loss. Unlike standard globe valves that force water to make a harsh 90-degree turn, the UltraFlow series features an innovative straight-through flow path. This greatly reduces friction, delivering more pressure and volume directly to your sprinklers and drip emitters.
Built with a heavy-duty glass-reinforced nylon body and a tough nylon-reinforced Buna-N diaphragm, this 1" valve is virtually indestructible. It is specifically designed to handle challenging conditions, featuring a built-in, self-cleaning 150 mesh filter screen that makes it ideal for dirty water applications like ponds, lakes, or wells. Combined with a slow-closing mechanism to prevent destructive water hammer, this 24V AC valve is a premium choice for high-demand systems.

Follow these steps to successfully install your inline valve.
Step 1: Prepare the Enclosure
Since this is an inline valve without an anti-siphon breaker, it should be installed underground inside a protective valve box. Dig a hole deep enough for the mainline and the box.
Step 2: Connect the Plumbing
Apply Teflon tape to 1" male PVC adapters and thread them into the inlet and outlet of the valve. Pay close attention to the flow direction arrows on the valve body—installing it backward will prevent it from opening.
Step 3: Wire the Solenoid
Run 24V direct burial wire from your irrigation timer to the valve box. Use silicone-filled waterproof wire nuts to splice one solenoid wire to the common wire and the other to the zone-specific station wire.
Step 4: Flush and Fine-Tune
Turn on the main water supply. Open the internal bleed screw to manually activate the valve and flush out any dirt or PVC shavings. Close the bleed screw, then use the top flow control dial to adjust the zone's pressure.
What is the benefit of a "straight-through" flow path?
In standard valves, water hits a wall and is forced upward through the diaphragm, causing a drop in pressure. The straight-through design of the UltraFlow allows water to pass directly through the valve body with minimal obstruction, preserving your system's water pressure for the emitters.
Will this valve work if I pump water from a pond or ditch?
Yes. The UltraFlow 700 series is specifically equipped with a self-cleaning 150-mesh filter screen on the internal metering rod, making it highly resistant to clogging from algae, sediment, and dirty water sources.
Should this valve be buried in a valve box?
Yes. This is an inline valve, not an anti-siphon valve. It is designed to be installed underground inside a protective plastic valve box to shield it from freezing, dirt, and lawnmowers.
Why is mid-May the perfect time to upgrade to an UltraFlow valve?
As mid-May warmth hits, neighborhood-wide water usage skyrockets, which often causes municipal water pressure to drop significantly. Upgrading to the straight-through UltraFlow valve right now ensures your system maximizes whatever pressure is available, preventing your sprinklers or drip lines from underperforming during the hot summer months.
