Features 1. Using
galvanized steel as material to make sure good insulation
performance, fire & corrosion resistance.2. Duration, long
service life.3. Easy installation.4. The flange is
bended directly by the frame.5. The valve size and color can
be customized according to customer's requirements.6. By DC24V
power to close the valveApplicationFire dampers are used
in air ducts of ventilation and air-conditioning system which
has smokeproofing and fireproofing requirements, especially
suitable for the important buildings that can not be reset
manually.Installation Attentions1. The valve body should be hoisted
independently to prevent the deformation of the pipe from affecting
the opening or closing of the valve.2. The valve can be installed
vertically or horizontally. No matter what kind of blade, the blade
must be parallel to the ground. If the blade cannot be parallel to
the ground, it must be declared when ordering.3. On the side of the
valve operator and on the other side of the spring mechanism, there
should be no less than 200mm of clearance for maintenance.4. When
the valve is installed in the ceiling, there should be an
inspection hole under the operator, the size is not less than
450*450mm.5. The connection between the fire damper and the
firewall should be insulated by refractory materials. The
electrical circuit should be protected by Ø20mm refractory
protection tube.6. When using the remote control operator, the
control cable should be protected by Ø20mm refractory tube. The
bending radius of the tube should be no less than 200mm, the
bending point should not exceed 3, and the cable should not be
longer than 6m.7. The cable wrapped around the operator should be
no less than 3 turns, and the cable head should be fastened with a
pressure plate.8. When the remote control operator is installed,
the installation box should be pre-installed on the wall. Please
refer to the remote control operator for the size of the
installation box. FAQ1. Are you trading company or
