1. Overview of the three-piece flanged pneumatic ball valve : The
three-piece flanged pneumatic ball valve adopts an integrated structure and is matched with a pneumatic actuator. It is beautiful in appearance, light and cheap, fast in disassembly and assembly, flexible in operation, simple in matching, and large in circulation. It is widely used in industrial automation systems in food, environmental protection, light industry, petroleum, papermaking, chemical, electric power and other industries.
2. Features of three-piece flanged pneumatic ball valve:
1. The valve body and end cover are made of dewaxing precision casting
2. The valve stem is designed to be explosion-proof
3. The flange connected pipeline can maintain good sealing performance, which is convenient for maintenance and replacement
4. Full flow diameter floating ball
5. High platform design adopting ISO5211 to directly install the actuator
6. Anti-static device between the ball valve and the ball
7. Double disc-shaped shrapnel automatic compression packing design
8. Three-piece high platform ball valve is usually used When the pressure and temperature are high, and the sealing requirements are strict.
9. The sealing surface has self-cleaning characteristics. When the ball is tilted away from the valve seat, the fluid in the pipeline passes through 360° uniformly along the spherical sealing surface. Flushing also washes away the accumulations on the sealing surface to achieve the purpose of self-cleaning. Therefore, in addition to controlling gas, liquid, and steam media, it is also suitable to control sewage and media containing fibrous impurities. Three. Three-piece flange pneumatic ball valve quotation instructions: 1. Valve body parameters: caliber, working pressure, valve body material, use medium, connection form and other parameters 2. Actuator: actuator form, control method, control signal (4 -20MA), mode of action (air-open type, air-close type) 3. Optional accessories: solenoid valve, limit switch, two-piece
