Hard seal butterfly valve application areas

Hard seal butterfly valve with its simple structure, convenient operation and excellent sealing performance, has become a key fluid control equipment for high temperature and high pressure, corrosive media and other harsh environments. This article focuses on its wide range of applications in the chemical industry (precise control, corrosion resistance), oil and gas (high pressure and high temperature transportation and processing), as well as electric power, metallurgy, papermaking (regulating water, steam, gas, pulp and other media) and other industrial fields, to meet the requirements of high stability and reliability, and to effectively improve production efficiency and safety.

How much is the price difference between soft seal butterfly valve and hard seal butterfly valve?

This article analyzes the price difference between soft seal and hard seal butterfly valve and the core difference. Hard seal butterfly valve price is usually higher than soft seal, DN300 caliber below the price difference of about 100-900 yuan (depending on the model). Key differences include: soft seal (rubber/polyurethane material, excellent sealing performance but short life, suitable for water/air and other conventional media); hard seal (metal material, high temperature and pressure, long life, suitable for chemical/petroleum and other harsh environments). Selection should be based on engineering needs and media characteristics to ensure system safety and efficiency.

Hard seal butterfly valve application environment and characteristics of details

Hard seal butterfly valves are widely used in all kinds of harsh industrial environments due to their excellent adaptability. It can reliably cope with extreme temperatures (from hundreds of degrees Celsius for high-temperature steam to low temperatures in cold regions), adapt to a variety of pressure levels (from medium and low pressure for water supply and drainage to high pressure for chemical processes), and be compatible with a variety of media (including gases, liquids, weakly corrosive solutions and materials containing solid particles), ensuring the sealing safety of piping systems and stable operation under various working conditions.
