Dramm® Brass Shut-Off Valve - 17 GPM - 3/4in Thread

Quarter-Turn Brass Shutoff Built for Decades of Greenhouse Service

The Dramm Brass Shut-Off Valve provides fingertip water control at the end of a greenhouse hose: a quarter turn of the large ergonomic handle and the water is off. Built from solid brass with durable seals and a hard chrome-plated ball, it is engineered to deliver years of reliable, full-flow service at up to 17 GPM through a 3/4in threaded connection.

The 3/4in thread fits standard greenhouse hoses and hose bib connections directly, and the quarter-turn ball design works equally well as a hose-end shutoff or as a branch- or main-line valve in greenhouse plumbing.

Key Features & Benefits

• Solid brass construction: Durability and corrosion resistance for professional greenhouse and hydroponic use over many years of service.
• Hard chrome-plated ball: Resists wear and corrosion at the sealing surface for consistent, leak-free shutoff over thousands of on/off cycles.
• Large ergonomic quarter-turn handle: Full water control with one simple 90-degree turn, operable comfortably with wet or gloved hands.
• Full-flow design: Unrestricted internal path delivers the rated 17 GPM without the pressure drop common in lesser valve designs.
• Made in the USA: Professional-grade craftsmanship trusted by commercial growers for decades.

Who Should Use This

Commercial greenhouse growers, nursery professionals, and hydroponic operators who want a durable, reliable hose shut-off valve for daily long-term use are the direct fit for this valve.

Frequently Asked Questions

How long can I expect this valve to last?

With proper use, a Dramm brass valve can last many years in commercial greenhouse environments. The chrome-plated ball and quality seals are specifically chosen for that kind of longevity.

Will the brass corrode in hydroponic nutrient solution environments?

Brass is generally durable in greenhouse conditions, but prolonged exposure to very acidic or high-EC nutrient solutions may eventually affect brass surfaces. The Dramm Aluminum Shut-Off Valve is recommended instead if aggressive chemistry is a concern.

Is the 17 GPM rating measured at a specific pressure?

Yes, flow ratings are pressure-dependent, and this figure applies at typical greenhouse supply pressure. At lower supply pressures, actual flow will be less than 17 GPM, so confirm your line pressure for an accurate estimate.

Can this be used as a main line shutoff?

Yes, the quarter-turn ball design makes it suitable as a branch line or main shutoff valve in greenhouse plumbing systems, not just as a hose-end valve. The full-flow 17 GPM rating and durable brass body hold up well to that kind of higher-duty plumbing role.
