High toughness 60si2mn spring is not easy to break or deform, and the piston and gear shaft have undergone high-frequency quenching treatment, with a long service life
• Two stage speed regulation: The door closer is equipped with two independent rotary valves on the side. By adjusting them, you can control the closing speed of the door within the range of 180 ° -15 ° and 15 ° -0 ° to meet your specific needs.
