Yuma YM714 Door Closer 60–90 kg No:4

Yuma YM714 Door Closer (60–90 kg / No:4)

The Yuma YM714 Door Closer (60–90 kg / No:4) is a robust automatic door closing mechanism designed for heavy-duty doors and high-traffic entrances. Its No:4 power class indicates that the closer is ideally suited to control door weights between 60 kg and 90 kg, and will provide the most efficient performance for doors within this weight range. This product ensures stable closing, especially for heavy doors exposed to external factors (wind, air pressure) that need to remain continuously closed.

Product Features and Material Details

The YM714 model is designed to provide high performance, reliability, and durability:

Mechanism Type: Door Closer (Heavy-Duty Door Closer).

Function: After the door is opened, the hydraulic fluid and strong spring system inside ensure the door closes in a controlled, stable, and reliable manner.

Power Standard: Conforms to EN 1154 Standard (No:4).

Load Capacity: Ideally suited for heavy door weights between 60 kg and 90 kg.

Door Width: Typically capable of controlling wide doors between 950 mm and 1100 mm. Guarantees strong closing for heavy and/or wide doors.

Speed Adjustment: Dual Speed Adjustment (Adjustable Closing Speed).

The closing speed can be precisely adjusted in two separate stages using the valves on the hydraulic body:

Main Closing Speed: The speed of the door from its initial open position to its final closing angle.

Latching Speed (Snapping Speed): Allows the door to accelerate or decelerate in the last 10-15 degrees of its closing arc. This is critical for the door to engage the lock fully and quietly.

Material:

Body: High-strength aluminum alloy or heavy-duty cast iron (with corrosion-protective coating).

Arms and Connection Parts: High-stress resistant reinforced steel or alloys.

Internal Structure: High-quality hydraulic oil and leak-proof seals for long life and stable performance.
