Dramm® #74 Full Flow Shut-Off Valve - 18 GPM - Ergonomic Insulated Grip

Full-Flow, One-Touch Control Built for Demanding Greenhouse Use

The Dramm #74 Full Flow Shut-Off Valve is built for durability and ease of use in professional greenhouse and hydroponic environments. Its one-touch lever-activated valve opens and closes instantly with a single squeeze, while the ergonomic insulated grip reduces hand fatigue during extended watering sessions. A 5/8in ball opening delivers full-flow water volume at up to 11 GPM at 40 PSI, and the fiber-reinforced polypropylene body keeps the valve lightweight without giving up the durability professional growers depend on day after day.

A standard 3/4in hose thread connects the #74 directly to greenhouse hoses and standard irrigation hose fittings, dropping into the same daily hand-watering role as any hose-end shut-off valve, just with a larger ball opening than most.

Frequently Asked Questions

How does the one-touch lever work?

Squeeze the lever against the handle to open flow, and release it to close. It operates with one hand, leaving the other free for plant handling or support.

What does the 5/8in ball opening mean for water flow?

The 5/8in ball opening matches or exceeds the inner diameter of most greenhouse hoses, so the valve does not restrict flow below the hose's rated capacity. That gives it its 11 GPM at 40 PSI rating.

Is the insulated grip heat-resistant?

The grip is insulated primarily for hand comfort during extended watering sessions. It is not rated for high-temperature fluid applications.

Is this valve repairable if it fails?

Dramm valves are built for a long service life, and the #74's fiber-reinforced body resists the corrosion that shortens the life of lesser plastic valves. Contact Dramm or your dealer for parts availability if service is needed after extended use.
