The JBL ProFlora v002 Solenoid Valve is designed to control CO2 supply via a timer (not included).
Using a timer with this valve means that you can set the CO2 supply to switch off in the evening when the supply is needed. It can also be used alongside a pH controller to dictate the CO2 supply according to the pH.
This expertly made accessory has been designed to work with the JBL CO2 Range, but can work with any compatible pressure reducer.
The V002 uses a 12v transformer for added safety, which also reduces noise and heat transference.
SAFETY NOTE: THIS SOLENOID VALVE SHOULD NOT BE USED WITH A NEEDLE VALVE, WITHOUT A PRESSURE REDUCER.
