Dramm® One Touch Valve - 8 GPM

Thumb-Tip Precision Water Control for Greenhouse Hand-Watering

Adjusting flow mid-task usually means letting go of the hose to reach a separate valve. The Dramm One Touch Valve puts that control at the thumb instead: a single smooth slide adjusts flow anywhere from fully off to fully open without releasing grip on the hose. The zinc die-cast body and nylon valve components hold up to daily commercial handling.

Rated at 8 GPM at 40 PSI, the valve suits hose watering throughout greenhouse bays, propagation benches, and indoor grow areas, and it holds steady at any partial-flow position along its slide range without continuous thumb pressure.

Key Features & Benefits

• Thumb-tip flow adjustment — slide from off to full flow without releasing grip, for one-handed control during active watering.
• Full range adjustment — flow sets anywhere between fully off and fully open, from gentle misting to high-volume watering.
• Zinc die-cast body — robust metal construction resists daily handling stress in commercial use.
• Nylon valve components — chemically resistant internal parts built for long service life in hydroponic and greenhouse environments.
• 8 GPM at 40 PSI — adequate flow for effective single-hose watering in most greenhouse and grow room applications.

Who Should Use This

Greenhouse growers and hydroponic operators who need quick, one-handed flow adjustment during hand-watering tasks, without setting down or regripping the hose, are the direct fit for the One Touch Valve.

Frequently Asked Questions

How is this different from the Dramm OneTouch High-Flow Valve?

This valve is rated at 8 GPM, while the Dramm OneTouch High-Flow Valve is rated at 16 GPM with a larger internal opening for greater volume output. Choose the 8 GPM version for typical single-hose hand-watering tasks.

Can I leave the valve set at a partial flow position?

Yes — the slide design holds at any position along its range without requiring continuous thumb pressure. That makes sustained partial-flow watering comfortable over a full task.

How does thumb-tip control differ from a lever valve?

Lever valves typically snap to fully open or fully closed. The One Touch slide instead gives smooth, variable flow control at any point in the range.

Is this valve repairable?

The nylon internal components are replaceable. Contact Dramm or your dealer for replacement parts and service information.
