5. Ọrụ na mmezi
The Cal-Royal CRN900PBF door closer allows for precise adjustment of closing speed, latching speed, and back-check to meet specific operational requirements and user preferences.
5.1. Adjustment Valves:
- Closing Speed Valve (Valve 1): This valve controls the speed at which the door closes from its fully open position until it reaches approximately 10-15 degrees from the closed position.
- Latching Speed Valve (Valve 2): This valve controls the speed of the door for the final 10-15 degrees of its closing cycle. Proper adjustment ensures the door latch engages smoothly without slamming.
- Back-Check Valve (Valve 3): This valve provides hydraulic resistance to slow down the door's opening swing, typically engaging after 70-80 degrees of opening. It helps prevent damage to the door or frame from forceful opening.
5.2. Adjustment Procedure:
- Identify Valves: Locate the adjustment valves on the door closer body. Refer to the product diagram or manufacturer's template for exact positions.
- Gbanwee ọsọ: Use an appropriate tool (e.g., a flathead screwdriver) to turn the adjustment valves.
- Turning the valve n'aka elekere ga-eme ibelata the speed (slow down the door).
- Turning the valve emegide-klookwaisi ga-eme mụbaa the speed (speed up the door).
- Test and Refine: Make small adjustments (typically quarter-turns) and test the door's operation after each adjustment.
- Start by adjusting the closing speed (Valve 1) to achieve the desired general closing pace.
- Next, adjust the latching speed (Valve 2) to ensure the door latches securely without slamming or failing to close completely.
- Finally, adjust the back-check (Valve 3) if the door is opening too quickly or forcefully.
