Brand: Habitech

Important: This 13mm size valve is not for 1/2 inch drip irrigation tubing. For use with 1/2" drip irrigation tubing, select the 16mm size valve.
Product Features:
- Simple on-off operation and straight through flow
- Operating pressure range 0 to 45 PSI at a temperature to 100°F
- Rapid quarter turn on-off operation
- Single barb inlet and outlet
- For low pressure applications
-Things to consider when installing valves in your system include:
- Selecting the correct barb size to match your tubing (see sizing chart)
- Ensure tubes are connected to both the inlet and the outlet of each valve
- Winterize your system if exposed to freezing conditions
- Limit your system pressure to a maximum of 300 kPa to ensure all devices and emitters function correctly

Important: Be sure to check the sizes and buy the right valve. This 13mm ball valve works with 1/2" tubing with 0.520 Inside Diameter (ID). If you need valves for 1/2" drip irrigation tubing, which has a larger inside diameter .570 to .620, then select the 16mm size valve.
