Different materials of the globe valve advantages and applications
The globe control valve /stop valve is a commonly used valve, which is suitable for a variety of different working conditions due to different materials.
Metal materials are the most widely used type of materials for globe valves. For example, cast iron globe valves are less costly and are commonly used in general industrial water systems and low pressure steam systems. It can withstand a certain amount of pressure, but the corrosion resistance is relatively weak.
The high strength of carbon steel 4 Inch globe valve is suitable for medium and high pressure fluid systems, such as pipelines transporting non-corrosive or weakly corrosive media in petroleum and chemical industries.
The stainless steel globe valve is used for the control of corrosive media with excellent corrosion resistance, such as food, pharmaceutical, chemical and other industries, for some pipe systems containing acidic or alkaline fluids, it can effectively prevent the valve from being damaged by corrosion.
In addition to metal, plastic globe valves also have many applications. Polyvinyl chloride (PVC) globe valve light weight, corrosion resistance, often used in water treatment, irrigation systems and other pressure requirements are not high, fluid corrosion is strong occasions.
The polytetrafluoroethylene (PTFE) globe valve Flanged has excellent chemical stability and high and low temperature resistance, and plays a role in the special reactor pipeline of the chemical industry or the ultra-pure water system of the semiconductor industry, because these fields have extremely high requirements for the purity of the medium and the corrosion resistance and temperature resistance of the equipment.
Ceramic globe valves are mainly used in harsh conditions of high wear and strong corrosion, such as slurry conveying pipelines in mines or corrosive medium pipelines containing a large number of solid particles in the chemical industry.
