Stainless steel galvanized steel corrosion protection manual electric electrical control 70c 280c HAVC ventilation system pipe smoke exhaust valve Fire valve
Fire valves are usually installed on ventilation ducts. The damper is normally open and will close when the air temperature reaches 70 °C.
The smoke exhaust fire valve is generally installed on the air duct of the smoke exhaust system. It's open normally. When there is a fire, the smoke detector will send out a fire alarm signal. The control center uses DC24V signal to exhaust smoke. When the flue temperature reaches 280 °C, it will automatically close.
The exhaust damper is generally installed on the air duct of the exhaust system. It's always closed. In the event of a fire, the smoke detector will send out a fire alarm signal. The control center sends an electrical signal to the solenoid valve on the damper to quickly open the damper, or manually quickly open the damper to exhaust the smoke.

The fire valve is used for the air duct of the ventilation and air conditioning system with smoke and fire prevention requirements, especially for important buildings that cannot be manually reset.
Installation precautions
1. The valve body should be lifted independently to prevent pipeline deformation from affecting the opening and 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 at the time of order.
3, on one side of the valve operator and the other side of the spring mechanism, there should be a gap of not less than 200mm for maintenance.
4, when the valve is installed in the ceiling, there should be an inspection hole under the operator, and the size is not less than 450*450mm.
5, the connection between the fire valve and the firewall should be insulated with refractory materials. The circuit is protected by Ø20mm fire-resistant protective tube.
6, when using the remote operator, the control cable should be protected by Ø20mm fire-resistant tube. The bending radius of the pipe should not be less than 200mm, the bending point should not exceed 3, and the cable length should not exceed 6m.
7. The cable wrapped around the operator should be no less than 3 laps, and the cable head should be fixed by the press plate.
8, when installing the remote control operator, the installation box should be pre-installed on the wall. Consult the remote control operator for the size of the mounting box.
