    Pneumatic Ball Valve

    Pneumatic Ball Valve Pneumatic ball valve is a kind of valve which is equipped with pneumatic actuator. The execution speed of pneumatic actuator is relatively fast, the fastest switching speed is 0.05 second/time, so it is also called pneumatic fast cut off ball valve. Pneumatic ball valves are usually equipped with a variety of accessories, such as solenoid valve, F.R.L, limit switch, locator, control box, etc. The advantages of pneumatic ball valve in the pipeline are on the below:

Zhejiang Sedelon Valve Co.,Ltd is a professional globe valve company with productive factory, we are the best globe valve, shut off valve, isolating valve, cut-off valve, disconnecting valve manufacturer and supplier from China.

The Globe vales play important roles in the flowing control of the fluid’s opening, closing and throttling.

The body of Globe valves may be made of metals. Such as: Forged Steel Globe valves, Stainless Steel Globe valves, Alloy Globe valves, Bronze Globe valves, Cast Steel Globe valves and Carbon Steel Globe valves ect.Among them, Forged Steel Globe valves which designed according to the standard of API 602 are widely used. We call them API 602 Forged Steel Globe valves.In addition, Sedelon® mainly produces Stainless Steel Globe valves according to the standard of API 603 (API 603 Stainless Steel Globe valves).According to different design standards, Sedelon® provides you DIN Globe valves as well.

The body can also be made of non-metal materials. For example, Ceramic Globe valves, which have good performance ofabrasionand hardness. Some other Globe valves are made of special materials, such as Hastelloy Globe valves Special Steel Globe valves and Special Alloy Globe valves.Transmitting and processing of media that are heavily corrosive, Duplex Stainless Steel Globe valves or Super Stainless Steel Globe valves are usually selected to mitigate the problems for they can work well in the area with corrosive surroundings.

The operation of Globe valves is simple, generally are hand wheel operated. We call them Hand Wheel Globe valves. When the valves need large amount of starting force, we can choose gear operated Globe valves which can save effort. Generally speaking, Big Size Globe valves are gear operated. Some SD (Sedelon ®) Globe valves can be equipped with actuator for special use. Such as Electric Motor Globe valves, Pneumatic Actuator Globe valves and Hydraulic Actuator Globe valves. Electric Motor Globe valves are durable because of the low friction between the seals in the process of opening and closing. Electric Motor Globe valves are not only suitable for mid and low pressure but also can withstand high pressure. However, this type of valves only allows fluid to flow forward one direction, thus whose installation is directional.

Globe valves have different connection types, which resulting in different kinds of Globe valves. They are Flanged Globe valves, Screwed Globe valves, Butt Weld Globe valves and Socket Weld Globe valves.

The Plug Type Globe valves with a plug-typed disc are transformers of the normal Globe valves.

Combined with the characteristic of no emission and swift on and shut-off service, this kind of Globe valves is widely used.

High temperature Globe valves can have an applicable temperature as high as 700℃。For high temperature conditions, we can also select High Nickel Alloy Globe valves. Low Temperature Globe valves which is also referred to as Cryogenic Globe valves can work in the temperature of -110℃。They are widely used in the industries of Liquefied Natural Gas and Liquefied Petroleum Gas, ect. Jacket Globe valves help to prevent the line fluid’s temperature loss. Under high pressure, Sedelon’s High Pressure Globe valves are good choices. A By-pass Globe valve is a pressure release system whose purpose is to reduce wear on the engine.Pressure Seal Globe valves can adjust the pressure of sealing ring automatically to fit with the different inner pressures in the pipeline. This type of Globe valves is usually used in high temperature and high pressure operating conditions.

For harmful and poisonous fluids, Bellows Sealed Globe valves can work well because of their good performance of sealing. Because of this character, they can also be applied to in the field of aseptic process industries such as medicine.

Nowadays, people pay much attention to environmental protection. We Sedelon also take it into consideration. Low emission Globe valves /Low leakage Globe valves can effectively prevent the medium leakage and emission, thus being good for the environment.Equipped with Fugitive Emission Test Certificate ISO 15848-1:2006, Sedelon manufactures Fugitive Emission Globe valves in order to make a contribution to protecting the environment.
