Pressure regulator for Hatsan BT65, Gladius, Galatian II and Flash helps stabilize the power of the rifle. It is also supplied with seals, which are used due to the poor internal surface of some air cylinders. The regulator is designed for models with a non-magnetic air cylinder with an internal diameter of 26.5 mm.
You can install the regulator quite easily. Just make sure the air is released from the cylinder, unscrew it from the rifle body, unscrew the cylinder valve, slide the regulator inside and screw the valve directly into the regulator. Then simply screw the cylinder back onto the rifle body. Installation of the regulator does not change the way the air is filled. You can continue to use the existing Quick Fill valve supplied with the rifle.
Adjusting the air pressure is very simple. The groove in the red semicircle serves both as a screw and as an indicator of the value between 100 and 150 bar. You only need to turn the screw with a screwdriver to the desired position. Adjustment is carried out only on a dismounted regulator.
