GROW1 3/4in 2-Way Electric Globe Valve 1-26GPM 24VAC

A 24VAC Electric Globe Valve for Automated Irrigation Zones

Every automated zone needs something that opens on the controller's signal and closes tight when the cycle ends. This GROW1 unit is a professional-grade, solenoid-operated 2-way globe valve built for hydroponics, greenhouses, nurseries, commercial agriculture and large indoor rooms. It is normally closed, so water only moves while the 24VAC solenoid is energized. A fully supported diaphragm handles a flow range of 1 to 26 GPM and gives drip-tight shutoff with quick open and close action. That range covers a small drip zone, a misting line or a full flood table bench on the same valve. Low inrush and holding current let it run on long wire runs from standard irrigation timers and controllers. An adjustable flow control handle sets the maximum flow on site, and a manual override opens the valve without the controller. Both ends take standard 3/4 in NPT threads, and the compact body mounts vertically or horizontally. The design resists clogging from debris and mineral buildup, and the body is rated for pressures up to 150 psi. It holds up to hard water, nutrient solutions, UV exposure and the humidity of a working greenhouse.

Setting Up the Irrigation Control Valve on a Drip or Flood Zone

Most growers put one valve per zone, plumbed after the main filter and wired back to a multi-station controller. Run the two solenoid leads to the station terminal and the common, using waterproof connectors at every splice. Fit a screen or disc filter upstream, because nutrient lines carry grit that wears any diaphragm seat over time. With the zone running, close the flow control handle until each emitter or sprayer delivers its target rate. That setting stops a short zone from robbing pressure from the longer ones. The manual override is handy for flushing lines or checking emitters without touching the controller program. Fertigation runs benefit too, since the valve shuts off cleanly the moment a dosing cycle ends. Diaphragm valves need line pressure to seal. On a gravity-fed reservoir with very little head, the diaphragm may not close fully, so a pump or pressurized supply works better. Leave room around the body to reach the handle and the override once the zone is plumbed in.

Key Features

• 1 to 26 GPM Flow Range: One valve size covers small drip zones up to full irrigation blocks.
• 24VAC Normally Closed Solenoid: Water moves only on the controller signal, with low inrush and holding current.
• Built-In Flow Control: An adjustable handle limits maximum flow so each zone gets its target rate.
• Manual Override: Open the zone by hand for flushing or checks without changing the program.
• Drip-Tight Diaphragm: A fully supported diaphragm seals cleanly between cycles and resists clogging.
• 3/4 in NPT, 150 psi Rated: Standard threads, vertical or horizontal mounting, and a high pressure rating.
