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
1. Product Introduction
Electric ball valve compare with the same sized gate valve and globe valve, it can all-closed and all-open when it rotate 90 degree. Valve channels diameter is equal with connection pipes diameter, so the medium can flow past without any leakage. Ball valve is a very important kind of valve, and widely used in the field of petrochemical industry and long-distance transport pipes. Its closure member is a part of globe with hole, and rotate along with valve rod to achieve open and close of valve.
2. Performance Feature
1. Apply to the occasion need two-position cut off and regulating.
2. Electric ball valve can achieve the medium cut-off and circulation functions in the transport pipeline of the petroleum industry, chemical industry paper making, metallurgy, sewage treatment and oil tank truck these fields.
3. High sealing performance and flow capacity, easy to assemble and maintain, small flow resistance, reliable seal.
4. Electric valve has the advantage such as small volume, light weight, large thrust, strong function, easy to operating, high reliability, and installed servo amplifier.
5. Can flow to any position, has wide adjustable range, and it can used for high pressure and big diameter occasion and to control the medium with high viscosity, fiber and fine particle.
6. Directly mounted type, with servo amplifier installed inside. Controlling and operating by output and input 4-20mA signal and 3800VAC voltage. It has the advantage such as easy to link, compact structure, stable and reliable operation.
