Working Conditions and Mediums for PVC Butterfly Valve

 

Butterfly valves come in a variety of styles, including rapid cut-off and continuous adjustment. Low-pressure, large-diameter liquid and gas pipelines are the most common applications. It's best for situations where the pressure loss isn't too great, the flow has to be adjusted, and the opening and shutting times are tight; typically, the temperature is below 300 °C and the pressure is less than 40 kg. The medium is commonly used for water and gas, and it is not difficult to work with. It's also possible to employ a granular medium. Water, condensate, flowing water, sewage, seawater, air, gas, liquid natural gas, dry powder, mud, fruit pulp, and mixes with suspended particles are all media that the PVC Butterfly Valve may convey and manage.

• The structural length is generally short in throttling, regulating control, and mud medium, and the opening and closing speeds are quick (1/4 revolution). A butterfly valve with a low-pressure cut-off (minimal pressure differential) is suggested.
• When two-position adjustment, narrow passage, low noise, cavitation and vaporization phenomena, a tiny quantity of leakage into the atmosphere, and abrasive media are required, the butterfly valve can be employed.
• It is necessary to use a specially designed metal seal with a triple eccentric or double eccentric adjustment device when the butterfly valve is used under special conditions, such as throttling adjustment, strict sealing requirements, severe wear, low temperature (cryogenic), and other operating conditions. For the ground, there is a special butterfly valve.
• Fresh water, sewage, seawater, salt water, steam, natural gas, food, medicine, and oil pipelines that require full sealing, 0% gas test leakage, high life requirements, and a working temperature range of -10°C to 150°C, as well as different acid and alkali and other pipes.
• The soft-sealed eccentric butterfly valve is designed for two-way opening and closing of ventilation and dust removal pipelines, as well as adjustment. It is widely utilized in metallurgy, light industrial, electric power, and petrochemical systems in gas pipelines and waterways.
• The metal-to-metal wire sealing double eccentric butterfly valve is used as a regulating and throttling mechanism in urban heating, gas, water supply, and other gas, oil, acid, and alkali pipelines.
• The metal-to-metal surface sealing triple eccentric butterfly valve may be utilized in petroleum, petrochemical, chemical, metallurgical, electric power, and other areas in addition to being employed as a large-scale pressure swing adsorption (PSA) gas separation device program control valve. It's both a gate and a stop valve. A nice substitute product.
