Netafim Inline Shut-Off Valve for Heavywall Dripline
Every drip system eventually needs a way to stop water to one row without shutting down the whole zone. This small hand valve does exactly that, item 00005-008960, model 58ISV520. Netafim lists it as the 13mm inline shut-off valve, grouped with its insert barb fittings for heavywall dripline. The 13mm figure describes the barb, which is sized for 16mm heavywall dripline with an inside diameter around 0.520 to 0.540 in. Older Netafim catalogs called the same part number the 16mm inline shut-off valve, which can cause confusion when matching tubing. Both ends are insert barbs, so the tubing pushes straight over each side. A lever handle on top opens or closes the flow path by hand. There is nothing to glue, thread or solder, which keeps installation fast in the middle of a crop. It is sold individually, so one valve covers one cut in the line. The compact body sits low on the dripline and is easy to reach along a bench edge.
Where a Drip Irrigation Shut Off Valve Saves Time
The most common use is isolating one bench, row or bed while the rest of the zone keeps running. That helps when a crop is being harvested, repotted or treated, and wet media would get in the way. It also lets a grower stop water to a row with a broken emitter or a split line until the repair is done. At the far end of a dripline, a valve in place of a line end becomes a flush point. Open it briefly while the zone runs and settled debris flushes out of the lateral. To install, cut the dripline square and push each end fully over the barbs. Push until the tubing covers the full barb, so the joint holds when the line pressurizes. Mount the handle where it can be reached without leaning over plants, ideally facing the aisle. Check the size against the tubing before cutting, since a barb that is too small will weep and one too large will not seat. This valve is a manual on-off fitting, not a pressure regulator, so pair it with a regulator upstream where pressure needs control.
