Hylands In-Line Drone Valves are for use with moisture control systems like the Ross Canister System, with 3 plastic tubes going to the drones. The moisture control system regulates humidity, while the in-line valves regulate airflow to the drones for clearer strike-ins and cut-offs. Unlike other drone valves, which are inserted in the drone stocks, the in-line valves are installed on the canister. The actual valve end fits in the canister system tubing, and the clear plastic end on the in-line valves fit over the plastic projections on the canister lid. Installation instructions are included, along with an adjustment key. 

 

Make tiny adjustments with the key; a little will go a long way.

 

Hylands In-Line Drone Valves require a zippered pipe bag and Ross Canister style system for installation.
