Pneumatic flange air flow cut-off valve SMD641W-6

Overview of Semir Products

SMD641W pneumatic ventilation butterfly valve is widely used in ventilation and dust removal systems, as a flow regulator and cutoff for dusty gases, gas pipelines, ventilation and purification devices, flue gas pipelines, etc. Butterfly valves are welded with high-quality wear-resistant materials, which have good wear resistance, stable and reliable operation, convenient operation, sensitive action, low leakage rate, long service life, and easy installation and maintenance. They are particularly suitable for low-pressure, large-diameter, and high flow applications. They are used in combination with various actuators to form valves with different performance. The SMD641W pneumatic ventilation butterfly valve is matched with an electrical valve positioner, and can be controlled by inputting a 4-20mADC signal and a 0.4-0.7MPa gas source to adjust parameters such as pressure, flow rate, temperature, and liquid level. Alternatively, a travel limit switch, solenoid valve, pressure reducing valve, and 0.4-0.7MPa gas source can be used to achieve switch operation, and two pairs of passive contact signals can be sent to indicate the valve's switch. Pneumatic ventilation regulating butterfly valves are mainly suitable for regulating the flow rate of ventilation media in industrial, metallurgical, environmental protection and other pipelines. Adopting electric or pneumatic transmission. Its applicable temperature depends on the material of the valve body, with a nominal pressure of ≤ 0.6MPa. It is generally suitable for use in industrial, metallurgical, environmental protection and other pipelines for ventilation and regulating medium flow.
