Pneumatic Vacuum Ductile Iron Stainless Steel Butterfly Valve

Product DescriptionPneumatic control valves are all kinds of pneumatic components that control the pressure, flow and flow direction of airflow in pneumatic systems and ensure the normal operation of pneumatic actuators or agencies. It is a type of valve that uses a circular disc or plate, known as the butterfly, to control the flow of fluid through the valve.Our AdvantagesThe main advantages of the pneumatic butterfly valve are its simple structure, small size, light weight, and low cost. These advantages are particularly significant for the pneumatic butterfly valve, which can be installed in high-altitude tunnels and is easy to operate through the control of a two-position five-way solenoid valve. The valve can also adjust the flow of the medium. The fluid resistance is small, and the effective flow area is large when the pneumatic butterfly valve is fully open, especially for medium and large diameters. The valve opens and closes quickly and easily, with the disc rotating 90 degrees to complete the opening and closing. Due to the nearly equal forces on both sides of the butterfly disc, the torque direction is opposite, resulting in a small opening and closing torque. Good sealing can be achieved under low pressure, and the sealing materials for the butterfly valve include NBR rubber, fluorine rubber, edible rubber, and PTFE lining, which have excellent sealing performance. Among them, the hard-sealed butterfly valve has the significant advantages of metal hard sealing and elastic sealing with a soft-hard layered metal sheet, and has excellent sealing performance even at low temperaturesScope of Application1.
