Key Specifications:

Air leakage rate (at 1000 Pa pressure differential) ≤ 700 m³/m²·h

Control voltage: 24 V DC

Operating current: ≤ 0.7 A

Micro switch contact rating: 220 V AC, 3 A

Rotation direction: Opens counterclockwise when activated

Actuation time: Instantaneous

Product Description:

1. The valve remains normally closed. In the event of a fire, the smoke (or heat) detector sends an electrical signal (24 V DC or 220 V AC) via the control center, which energizes the solenoid inside the actuator, causing the valve to open automatically and outputting an open signal.

2. The valve can be opened manually.

3. The valve must be manually reset after operation.

Product Structure:

Main Components: Valve body, blades, shaft, shaft sleeve, temperature sensor, actuator, stainless steel spring plate, torsion spring, etc. An intermediate frame is added in the W direction, and the blades are separated.

Maximum Valve Dimensions: 1200 × 800

The torsion spring torque of the actuator can be adjusted to three levels. Dimensions (OWXH) are designed to match duct sizes; flange dimensions comply with those for metal rectangular ducts specified in the Chinese national standard GB50234-2002.

Operating Conditions:

Static Pressure: Below 1500 Pa

Maximum Air Velocity: 15 m/s

Ambient Temperature: -10°C to 50°C

Ambient Humidity: Relative humidity below 85%

Important Notes:

1. Do not apply paint to the exterior of the actuator, and do not apply oil to electrical components, as this may cause malfunctions.

2. Fire dampers are critical to life safety and must be installed and commissioned by qualified professionals. During normal operation, perform routine inspections of the opening and closing mechanisms, electrical signal operations, and temperature sensors every six months.
