Fire-Rated MDF Kit Valve Activator for Building Smoke Management Systems with Fail-Safe Operation

Fire-Rated MDF Kit Valve Activator for Building Smoke Management Systems with Fail-Safe Operation

Product Description:
The Fire-Rated MDF Kit Valve Activator is a critical life-safety component engineered specifically for building automation and smoke control systems. In the event of a fire, it is responsible for automatically operating dampers and valves within HVAC ducts to manage the spread of smoke and toxic fumes, creating safe egress routes and protecting property. This actuator is built to rigorous fire-resistance standards, maintaining operational integrity even when exposed to high temperatures for a specified duration. Its core function is reliable fail-safe operation; upon receiving a fire alarm signal or a power failure, it will automatically drive the damper to a predetermined safe position—either fully open to vent smoke or fully closed to compartmentalize the fire. The robust design ensures that it functions precisely when it is needed most, providing emergency responders and building occupants with vital time. Constructed with non-flammable materials and featuring high-temperature lubricants and seals, this MDF Kit Valve Activator is a cornerstone of modern fire protection engineering, ensuring compliance with international building codes and safeguarding human lives.

Bullet Points:

• Certified for integration into critical smoke management systems.

• Provides essential fail-safe operation to a pre-set position upon alarm or power loss.

• Constructed with fire-resistant materials and high-temperature components.

• Ensures reliable damper control in HVAC ducts for life safety.

• Complies with major building codes and fire safety standards (UL, CE).

Specific Application Scenario
In a high-rise office building, this activator is installed on a smoke damper within a ceiling plenum. When the fire alarm is activated, it automatically closes the damper to prevent smoke from spreading into the stairwell, a designated fire escape route.

Factory Production Floor
Production takes place on a dedicated line with strict traceability for all components. Each fire-rated actuator undergoes a functional test that simulates a fire alarm signal to verify its immediate and correct fail-safe operation.

Packing and Transportation
Each unit is packaged in a distinctive red box (where applicable by industry norm) to signify its life-safety purpose. The packaging includes clear labels indicating "Fire-Rated Equipment" and "Handle with Care."

FAQ
1. What is the difference between a fail-safe open and fail-safe close actuator?
Fail-safe operation means the actuator moves to a predefined position without power. "Fail-Safe Close" secures the damper to contain fire/smoke. "Fail-Safe Open" opens the damper to vent smoke from a specific area like a staircase.

2. How long can this actuator withstand high temperatures?
It is typically rated to operate normally in ambient temperatures up to 125°C and to survive exposure to higher temperatures (e.g., 250°C for 1-2 hours) without compromising its structural integrity, ensuring it functions during a fire event.

3. Is it directly connected to the fire alarm panel?
Yes, it is designed to be interfaced directly with the building's central fire alarm control panel or a dedicated smoke management system controller for instantaneous activation.

4. What type of damper control does it provide?
It typically provides modulating or two-position (open/close) damper control for ventilation and smoke control dampers, ensuring precise airflow management during both normal and emergency conditions.

5. What are the routine testing requirements?
We recommend a monthly functional test, as per most fire codes, where a signal is sent to the actuator to verify it moves to its fail-safe position correctly.

Future industry manufacturing complex spans an area of nearly 7,000 square meters. It incorporates six high-speed aerosol valve production lines and more than 30 special valve production lines.

Each year, Future industry aerosol can produce up to one billion aerosol valves. Our main products are air freshener aerosol valve, insecticide spray aerosol valve, butane gas aerosol valve, carburetor cleaner aerosol valve, ribbon spray aerosol valve, snow spray aerosol valve,paint spray aerosol valve, fluid spray aerosol valve, portable stove gas aerosol valve, 360 degree aerosol valve, powder spray aerosol vave. Also we have expanded the export market of aerosol metering valves, aerosol caps and aerosol cans.We have also built five standardized workshops to conduct different operations in order to meet the requirements of various customers to ensure we always meet production demands and timelines.

Production of the valve mounting cups is carried out in this workshop. We use a high-speed automatic stamping machine to transform high-quality steel plates into valve mounting cups. Due to the high degree of its automation, this equipment can help to reduce labor costs and increase production efficiency significantly.

In addition, we utilize an efficient machine that can automatically press an outer rubber ring into a valve mounting cup in order to provide superior sealing performance in the process of final assembly.

This workshop contains over 20 injection molding machines and three injection molding lines. Among them, our injection molding machines are used to produce a variety of accessories such as valve stems, valve chambers, actuators, and spray caps, etc.

Due to efficient automation, we require a very small number of staff to run these more than 20 injection molders. During the production process, our quality control inspectors are responsible for sampling and testing every batch of accessories. Additionally, our injection molding line has the capability to produce various sizes of dip tubes in automatic mode.

This workshop is used to assemble all kinds of accessories. It is equipped with automated assembly equipment to greatly increase production efficiency and provide our customers with enhanced profits.

After assembly is completed, our valves will be automatically counted and packed. We are proud to say we are one of the few companies in the industry that possess advanced abilities in product research and development. Every new product needs an innovative mold. For this reason we utilize high-precision wire cutting machines and machine tools that can form our molds into exquisite shapes.

We possess a wide range of technical production and R & D expertise
