Description
The PolarStar F2™ poppet valve is available in two levels: Red and Gold. The Red valve is the standard valve included with the F2™ and provides the highest airflow in this system. This makes it well-suited for airsoft guns intended for outdoor fields within allowed power limits.
The optional Gold valve expands the capabilities of the F2 system by making it more flexible and adaptable for tuning different builds. By replacing the Red valve in the F2™ HPA unit with the Low Flow Gold valve, you can lower the power range of the gun. This allows the gun to operate at high pressures while keeping the output power low. Sufficient operating pressure ensures flawless performance of the F2 unit even at very high rates of fire.
The Low Flow Gold valve is particularly useful in situations where an airsoft gun with a long barrel needs to be tuned to low power levels, which may not be achievable within the regulator’s adjustment range.
Below is a comparison chart provided by PolarStar Airsoft showing the power output of the two different F2™ valves at various pressures and BB weights.
