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

Simply the Best Shut-Off Valve — Brass, Full Flow, Made in USA

Dramm calls this simply the best shut-off valve available, and after decades of use in professional greenhouses and grow operations worldwide, that reputation holds. 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.

Key Features & Benefits

• Solid brass construction — proven 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 rated 17 GPM without the pressure drop common in lesser valve designs.
• 3/4in threaded connection — standard thread fits greenhouse hoses, manifolds, and irrigation fittings directly.
• Made in the USA — professional-grade craftsmanship trusted by commercial growers for decades.

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 longevity.

Will the brass corrode in hydroponic nutrient solution environments?

Brass is generally durable in greenhouse conditions; however, prolonged exposure to very acidic or high-EC nutrient solutions may eventually affect brass surfaces. The aluminum Dramm valve is recommended if aggressive chemistry is a concern.

Is the 17 GPM rating at a specific pressure?

Yes — flow ratings are pressure-dependent. At lower supply pressures, actual flow will be less than 17 GPM. Confirm your supply pressure for accurate flow estimates.

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.
