These one-way valves help keep simulated clots from being drawn back into the squeeze bottle while using our Task Trainers. The valves should be flushed with water after use and before storage to maintain the longest operating life. Each of our Task Trainers come with two valves (one installed, one spare.) However, sometimes the valves get lost, broken or worn out.
Please note that there is an arrow on the valves showing the direction of flow. Please install the valve with the arrow pointing towards the Task Trainer.
