Netafim Manual Valve for 4/7 mm Micro-Tubing, Barb x Barb, 10 Pack (EDTUBEMVLV-B)

Netafim Micro Valve, Barb x Barb for Micro-Tubing

In a propagation house, one head over an empty bench or a finished tray is often the only one that needs to stop. This manual valve, Netafim item 76220-009360 and model EDTUBEMVLV-B, lets that one head be shut off by hand. It is an inline valve with a barbed connection on each end. The barbs suit 4/7 mm micro-tubing, which has an inside diameter of about 0.16 in. A ribbed knob on top opens and closes the flow. Turning it isolates a single micro-sprinkler, mister or fogger while the rest of the line keeps running. The compact black body splices straight into a single drop or lead. It is used in greenhouses, tunnels and other closed structures. Typical crops include young seedlings, multicell trays and forest seedlings. Each bag contains 10 valves for a bench or a full house.

Splicing a Valve Into 4/7 mm Micro Tubing

Netafim hanging assemblies for sprinklers, misters and foggers use Super Flex UV White tubing in this same size. The valve sits among the accessories for those assemblies, alongside connectors, weights and head plugs. Cut the tube where the shut-off should go and push one cut end onto each barb. Set the valve where the knob can be reached from the aisle or bench edge. Opening the knob again brings that head back as soon as the bench is replanted. Sprinkler and mister zones feeding these lines run through a 35 psi regulator and a 120 mesh filter. Fogger zones use a 65 psi regulator with 140 mesh filtration. Flush the supply pipes before heads with check valves go on, so debris stays out of the valve and nozzle. The check valve in each Netafim head still holds its line full after shutdown. Fit a valve on as many drops as the layout needs.
