ultra small flow needle valve is a kind of top guide single seat valve, it has a simple structure, good sealing performance, reliable use and so on. The top guide system is effective enough to overcome the small opening shock, effective and long service life. A smaller flow coefficient is chosen to increase the use of the valve. Multi spring pneumatic film mechanism or electric actuator can be selected. The valve is the use of , professional development of a small flow of the operating conditions of a product. The body is small in size and light in weight, and the inner screw thread structure is more convenient to be installed and disassembled. The whole body has the characteristics of small size, light weight, high performance and precise control of micro flow.Does not apply to the medium of the more dirty occasions, adjusting the media containing granular media, should be aimed at the problem of small throttle clearance, pay attention to prevent the occurrence of blocking card phenomenon. Especially suitable for liquid, steam and other media in the mainstream of the regulation. required.

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
