气动衬四氟法兰球阀 Q641FS


   气动衬四氟法兰球阀



Features:

The fluor-lined pneumatic ball valve features a fluoroplastic-lined valve body combined with an innovative stem-integrated ball design and a unique elastic lip-seal seat structure. This configuration retains all the advantages of standard ball valves while delivering superior sealing performance under high pressure differentials and wide temperature fluctuations, along with low operating torque. Suitable for both on/off and regulating applications, this valve is ideal for handling liquids and gases (including steam) in industrial pipelines, demonstrating excellent resistance to strongly corrosive media such as acids, alkalis, and salts. The full-bore design ensures maximum flow capacity and supports pipeline purging, cleaning, or isolation.


Operating Temperature: -80°C to 200°C

Standards Compliance:


Design Standard: GB/12237


Face-to-Face Dimensions: GB/12221


Flange Standard: GB/113.1-26


Inspection Standard: JB/T 9092-99


Main Components & Materials:

The valve body of the fluor-lined pneumatic ball valve is lined with fluoroplastic, paired with an advanced stem-integrated ball structure and a proprietary elastic lip-seal seat. This combination ensures the valve's high sealing integrity even under extreme pressure and temperature variations, with minimal operating torque. It functions reliably for isolation or flow control in pipelines transporting liquids, gases (e.g., steam), and highly corrosive fluids (acids, alkalis, salts). The full-bore construction optimizes flow efficiency and facilitates pipeline maintenance or segregated flow routing.


Standards:


Temperature Range: -80°C to 200°C


Design: GB/12237


Structural Length: GB/12221


Flanges: GB/113.1-26


Testing: JB/T 9092-99


Key Advantages:


Corrosion Resistance: Fluoroplastic lining withstands aggressive chemicals.


Bidirectional Sealing: Reliable performance in high ΔP and thermal cycles.


Low Torque Operation: Energy-efficient actuation.


Versatility: Full-bore design for unrestricted flow or pigging.


Compliance: Meets stringent Chinese industrial standards.


Note: Ideal for chemical, petrochemical, and HVAC systems requiring leak-proof fluid control.
