Umarex Notos / PP750 PEEK Low Force Valve

Upgrade PEEK Low Force Valve for Umarex Notos / Artemis PP750. Smaller valve sealing surface: requires ~30% less hammer strike force to open the valve. To get optimal result regulator pressure & hammer preload adjustment is required.

Valve body is precision machined from high quality PEEK material. Mated to polished hardened steel stem. Optimized sealing surface geometry makes the valve easier to seal.

PEEK is much harder and stronger than factory Delrin valve, and is well suited for high pressure applications.

Installation note:

-The Low Force Valve requires less hammer strike force to open. After installation, you can choose to reduce hammer spring pre-load, or you can set higher regulator pressure for more power. It's the buyer's responsibility to make sure that the velocity / muzzle energy doesn't exceed local allowed limit. Since user tuning is required, we do not guarantee performance improvement from valve replacement alone.

-It's possible that you get a slow leak first time filling up after installing the new valve. This is due to the valve not being fully seated or small debris between the valve and the seat. Simply dry fire a few times while the cylinder is pressurized, this will create a seal and leak will stop from now on. PEEK is harder to seal and might require higher regulated pressure.

DO NOT fire when the cylinder is not pressurized!

You will get 1 poppet valve. Valve body and spring are for demonstration only, and are not included.
