Constant Air Volume ValveStandard Model: MS/MCA constant air volume regulator is an air engineering device that maintains a constant airflow rate within a range of pressure fluctuations without requiring any external power source. The device begins to operate according to its rated size and set airflow rate when the minimum pressure difference across the controller reaches 35 to 55 Pascals. Higher pressure differences are required for controlling larger airflow rates. Using a constant air volume controller provides HVAC designers with a preferred solution for air distribution system design that requires no external energy source while meeting various preset operating conditions.The DOCK-AIR constant air volume regulator is designed for ventilation systems to maintain a constant airflow rate. This device operates without electricity within a minimum to maximum pressure difference range. Accuracy of the maintained airflow may decrease outside this pressure difference range. This r...

Normally Closed Supply Air ValveStandard Model: SFF SDc-CCVProduct DescriptionThe normally closed supply air valve is typically installed in the ductwork of ventilation and air conditioning systems. It remains in a closed state and only opens to supply air under specific circumstances.The opening of the normally closed supply air valve is usually triggered by a fire alarm system or other control signals. In case of fire or other emergencies, the fire alarm system sends a signal, and the actuator receives the signal and performs the corresponding action. For example, a motor drives the valve plate to overcome the closing resistance and begin rotating. As the valve plate rotates, the duct is gradually opened, allowing outside air to be smoothly delivered to the required areas, such as the vestibule and stairwells of the fire-affected floor, providing fresh air for personnel evacuation and firefighting operations.During the air supply process, the valve plate remains in the open position,...
Smoke Exhaust ValveStandard Model: PYF-SDC-KProduct DescriptionA smoke exhaust valve is a device installed in the ductwork and air transfer openings of air distribution or smoke control systems. It is designed to prevent the penetration of air and smoke. The device is automatically controlled by a smoke detection system and can also be opened and closed remotely from a fire command center as needed. Its core function is to prevent smoke from spreading through the HVAC system or from one side of a fire compartment to the other.This device is typically used inside the ductwork and air supply openings of smoke control or air distribution systems. It is specifically designed to close automatically upon sensing heat or smoke. Furthermore, it blocks airflow, effectively controlling the spread of fire by preventing flames from spreading from the point of origin to unaffected areas.The smoke exhaust valve is controlled by smoke or temperature sensors. When the smoke concentration ...
Smoke and Fire DamperStandard Model: PFHF WS-KProduct DescriptionSmoke and fire dampers are used in building partitions that require both fire resistance and smoke containment. They simultaneously fulfill all functional requirements for both fire and smoke protection. If you need a barrier with both fire and smoke protection capabilities in the same location, this product is your ideal choice.These dampers are typically installed in penetrations of HVAC systems and are suitable for walls, ceilings, or floors where both fire and smoke protection are required. Their closure can be triggered in two ways: by a smoke detector sensing smoke, or by a duct temperature sensor detecting abnormal heat.Traditional fire dampers rely on a fusible link mechanism, while smoke and fire dampers can be equipped with an electric thermal release device. The advantage of this device is that it is resettable and allows for smooth, controlled closure, thus avoiding pressure fluctuations in the HVAC ...
