What does the valve stem do in OC spray delivery?

• A. Regulates the amount of product delivered to the nozzle.
• B. Determines the spray pattern.
• C. Controls the device temperature.
• D. Locks the safety cover.

Answer: (A)

The valve stem is the part that meters how much OC spray is released with each actuation. When you press the trigger, the stem moves to open the valve just enough to send a measured amount of liquid through to the nozzle. How long the stem stays open and the size of the opening determine the quantity delivered each time, so it directly controls the amount that exits the canister. The spray pattern comes mainly from the nozzle design, not the stem, and temperature control or safety locks are managed by other components.
