What are the applicable occasions for bidirectional hard seal butterfly valves?
Bidirectional hard seal butterfly valve is a high-performance valve that has characteristics such as high temperature resistance, corrosion resistance, wear resistance, and waterproof against steam leakage. Therefore, it is widely used in various fields. Here are some examples of its applicability:
Chemical industry: Bidirectional hard sealed butterfly valves have characteristics such as acid and alkali resistance, corrosion resistance, and wear resistance, making them widely used in flow control of various chemical pipelines, such as acid washing, chlor alkali production, petrochemical industry, fertilizer production, etc.

In the fields of food, beverage, and pharmaceuticals: Bidirectional hard sealed butterfly valves have the characteristics of meeting hygiene standards, so they are widely used in flow control of various food, beverage, and pharmaceutical production pipeline systems, such as beer, fruit juice, dairy products, pharmaceuticals, etc.
In the field of petroleum and natural gas: Bidirectional hard sealed butterfly valves have the characteristics of wear resistance and waterproofing against steam leakage, making them widely used in flow control, isolation, and cutoff of various petroleum and natural gas pipeline systems.
In the field of sewage treatment: Bidirectional hard sealed butterfly valves have the characteristics of high temperature resistance and dirt resistance, so they are widely used in flow regulation and isolation of sewage pipelines.
Metallurgy and steel fields: Bidirectional hard sealed butterfly valves have the characteristics of wear resistance and high temperature resistance, so they are widely used in cooling cycles and other fluid pipeline systems under high temperature and high pressure conditions in metallurgy and steel production.
In summary, bidirectional hard seal butterfly valves are widely used in various industries. Their characteristics such as wear resistance, high temperature resistance, corrosion resistance, compliance with hygiene requirements, and waterproofing against steam leakage make them excellent in flow control, isolation, and cutoff.
