Dramm - Micro Tube Shut-Off Valve

Brand: Dramm

Micro Tube Shut-Off Valve

A barb-by-barb mini valve that splices into micro tube between the lateral and a single emitter, dribble ring or stake. Dramm describes the 1/4 in version plainly: a barbed microvalve for drip irrigation that allows individual pressure compensated drippers to be turned off. One pot, basket or bench position comes out of service without capping the line or pulling the dropper.

The only decision is barb size, and it is set by the tube you are cutting into. The 0.25 in barb x barb valve suits Dramm 0.191 in OD leader tube - the tube PCAS emitters and droppers use - and is the version Dramm publishes as the 1/4 in Microvalve. The 0.12 in barb x barb valve is the smaller inline mini valve for the fine dribble-tube bores, the 0.045, 0.060 and 0.075 in ID tubing. Hold the tube against the barb before ordering in quantity; a valve one size out will either not seat or will not seal.

Specifications

Configurations

Key Features

• Isolates a single dropper instead of a whole run
• Two barb sizes cover both the PCAS leader tube and the fine dribble tube bores
• Fits in the leader tube ahead of a dribble ring, where Dramm shows it as the optional individual shut-off
• Cheap enough to fit as standard on every basket position rather than only where problems appear

Ideal Applications

• Shutting off a single hanging basket or pot without draining the zone
• Taking an empty bench position out of service between crops
• Isolating a leaking dropper until it can be replaced

Pairs with 0.191 in micro tubing, PCAS emitters and drip assemblies, and Dramm dribble tubes and PC rings.
