Why Use Individual Flow Control Valves?

Every plant has different watering needs. These valves give you the flexibility to dial in the exact flow rate for each line in your irrigation system.

Frequently Asked Questions

Q: What size drip irrigation tubing are these flow control valves compatible with?

A: These valves are designed specifically for 4mm and 7mm drip irrigation tubing, which is the most common size used in home garden drip systems. They push directly onto the tubing without any tools or additional fittings.

Q: Can I use these valves with high-pressure water supplies?

A: These plastic flow control valves are rated for pressures under 850 kPa. They are suitable for standard residential garden water supplies. If your water pressure exceeds this rating, we recommend using a pressure regulator before your drip system.

Q: How do I install the valves in my drip irrigation system?

A: Simply push the valve inline between sections of your 4/7mm drip tubing. Turn the valve dial to open, restrict, or completely shut off the water flow to that particular line. No tools are needed for standard push-fit installation.

Q: Are these valves suitable for outdoor year-round use?

A: The valves are made from plastic and are corrosion-resistant, making them suitable for outdoor garden use. In regions with freezing winters, it is recommended to drain and store irrigation components to prevent cracking from ice expansion.
