The pneumatic regulating butterfly valve has the advantages of simple and compact structure, convenient processing, easy to manufacture large diameter, self-cleaning action, small drag coefficient and large circulation capacity. It is additionally equipped with a valve positioner, which can be controlled by input control signals (4-20mADC) and a gas source of 0.4-0.7MPa. Pneumatically regulated butterfly valves are suitable for the regulation of fluids in suspended particles and in concentrated, turbid slurry fluids. Clean media can be replaced with a valve plate with a soft seal (rubber ring, PTFE ring) to reduce leakage (up to zero leakage). The high-temperature and high-pressure working conditions can be selected by a three-eccentric hard sealing valve body. Pneumatically regulated butterfly valves are the best means of regulating flow and shutting off fluids in automated control systems. Therefore, the pneumatic regulating butterfly valve is widely applied to the pipeline of corrosive medium such as metallurgy, electric power, petroleum, chemical, air, gas, combustible gas and water supply and drainage with medium temperature â?¤550°C.

The pneumatically regulated ball valve is a rotary ball valve with a 90° angle, which can also be called a pneumatic O-type ball valve. It is composed of a pneumatic actuator with a quarter stroke and a ball valve. It is a specially designed and carefully manufactured product based on the introduction of foreign advanced technology. The pneumatically regulated ball valve adopts intelligent control and positioning, and it is matched with the electric valve positioner. It can control the operation by inputting 4~20mADC signal and 0.4~0.7MPa air source to realize the adjustment of pressure, flow, temperature and liquid level. Pneumatically regulated ball valves are powered by compressed air. The valve stem drives the valve core to rotate 90° in the valve body to achieve full-opening-closed action. Pneumatically regulated ball valves are classified into metal seals and soft seals according to their sealing properties. The pneumatic O-type regulating ball valve has the advantages of compact structure, small volume, reliable operation, good sealing performance, easy maintenance, convenient installation and strong adaptability. Pneumatically regulated ball valves are particularly suitable for applications where the media is viscous, particulate-containing, or fibrous. Pneumatically regulated ball valves are widely used in industrial automation control systems such as petroleum, chemical, teaching equipment, light industry, high-voltage equipment, pharmaceutical, papermaking, etc. for long-distance centralized control or local control

Overview of pneumatic regulating ball valve: According to the structural form, the pneumatic regulating ball valve can be divided into pneumatic O-type regulating ball valve or dynamic V-type regulating ball valve. It is mainly used with the valve positioner to make a press signal according to the input and output 4.20mA, so that Control the rotation opening of the ball valve valve. To achieve the proportional adjustment of pipeline medium pressure, flow rate, liquid door and other parameters, among them, the pneumatic/type adjustment glass closure has knotted and removed shape objects (throwing gaps, which can adjust the flow rate according to the change of the opening area in the middle of the field, and can cut off the fluid Closed by impurities contained in the medium, suitable for the control of pulp, mortar, viscous fluid, Pneumatic regulating ball valve principle: The pneumatic regulating ball valve uses compressed air as the driving force to drive the ball flower to rotate back and forth, so as to achieve the opening and closing of the valve. Size, to achieve different degrees of proportional adjustment to the medium flow. When the pneumatic actuator receives the signal from the control system, it generates a corresponding thrust according to the size of the control force, and pushes the adjustment mechanism to drive the valve core to move, and completes the flow and pressure adjustment of the medium in the pipeline. It has a large rated flow coefficient. , good sealing effect, adjustable performance, etc.
