A flanged ball valve is a quarter-turn valve that uses a hollow, perforated and pivoting ball to control the flow of liquid or gas.  It adopts flange connection design for easy installation and maintenance.  This valve is widely used in various industries such as oil and gas, petrochemical, water treatment, power generation, etc. due to its reliable performance and durability.

the advantages of flanged ball valves include their versatility, ease of installation and maintenance, high flow capacity, tight sealing, durability, wide range of options, and safety and reliability, making them a preferred choice for many industrial fluid and gas control applications.

Trunnion-mounted ball design, robust construction, and reliable performance make it an ideal choice for a wide range of industries. 

The floating ball valve has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as People's Daily life. It has several advantages that make it a popular choice in industrial applications. 

Chemical plants often need to use ball valves with specific characteristics and functions to meet their special process requirements. The following are the types of ball valves Yongjia Dalunwei Valve Co., Ltd has provided to chemical plants:High temperature and high pressure ball valves, these ball valves ensure reliability and safety in high temperature and high pressure environments. Low temperature ball valves, these ball valves usually use low temperature materials and seal design to ensure reliability and sealing performance in low temperature conditions. Corrosion resistant ball valves, these ball valves are usually made of special materials or coatings, such as stainless steel, alloy steel or ceramics, to resist the corrosion of chemical media.
