Hydraulic Fan Gate Valve

The Hydraulic Fan Gate Valve is a specialized heavy-duty control device widely used for wind pressure isolation, air duct cut-off, and bulk material sealing in industrial ventilation and dust removal systems. Featuring a unique fan-shaped gate structure and hydraulic driving system, this valve is designed to solve the problems of large air volume, high wind pressure, frequent switching, and poor sealing of traditional air duct valves. It is mainly applied in thermal power plants, cement industries, metallurgy, chemical plants, environmental protection dust removal systems, and large-scale ventilation pipelines, serving as core equipment for air flow adjustment, pipeline isolation, and system safety protection.

Different from conventional flat gate valves and butterfly valves, the Hydraulic Fan Gate Valve adopts an innovative fan-shaped swing gate design. The arc-shaped fan gate rotates around a fixed shaft to realize quick opening and closing actions. When fully open, the gate completely exits the flow channel, forming a straight and unobstructed air passage with minimum wind resistance and no turbulence, ensuring the maximum conveying efficiency of ventilation and dust removal systems. When fully closed, the fan gate closely fits the valve seat through hydraulic thrust, achieving excellent airtight sealing effect and effectively preventing air leakage, wind pressure loss, and dust backflow.

Equipped with a professional integrated hydraulic drive system, the valve features strong driving force, stable operation, and anti-interference capability. The hydraulic actuator provides powerful and uniform thrust, enabling the fan gate to complete switching actions smoothly even under high wind pressure and large air volume conditions. The whole operating process is free of jitter, stuck movement, and impact noise. With built-in hydraulic self-locking function, the valve can stably maintain the opening and closing position without displacement under sudden wind pressure fluctuation, greatly improving the safety and stability of the entire ventilation system. It supports manual local control and electric remote control, and can be docked with PLC automatic control system to realize intelligent linkage operation.

The valve body is made of high-quality carbon steel plate through integral welding and stress relief treatment. The overall structure is rigid and firm, with strong wind pressure resistance and deformation resistance. The fan gate is thickened and reinforced, and the sealing surface adopts precision processing and high-performance wear-resistant and high-temperature resistant sealing materials. It can adapt to long-term operation in harsh environments such as high-temperature flue gas, dusty air flow, and variable wind pressure. Compared with ordinary air valves, it has longer service life, lower failure rate and better sealing stability.

In industrial practical application, the Hydraulic Fan Gate Valve shows prominent advantages. Its fan-shaped swing structure avoids material accumulation and dust clogging, realizing self-cleaning during switching. The hydraulic drive realizes soft start and soft stop, effectively reducing pipeline vibration and system impact. The simple and compact structure brings convenient installation, inspection and maintenance, reducing daily operating costs. In addition, the valve can be customized in terms of caliber, pressure resistance and structural form according to different working conditions.

Mainly used for flue duct isolation, dust removal pipeline cut-off, ventilation system switching, and air volume control, the Hydraulic Fan Gate Valve is an essential supporting equipment for ensuring efficient operation, energy saving and consumption reduction, and safe production of modern industrial ventilation and dust removal systems.
