Butterfly Valves C.I. Body S.G. Iron Disc with Pneumatic Actuator

  1. Design and Size:

    • These butterfly valves have a wafer type design, conforming to API 609 (CAT – A).
    • They are available in sizes ranging from 1.1/2″ to 12″.

  2. Pressure Ratings:

    • The valves are suitable for ASME B16.5 150# flanges.
    • They can handle pressure ranges of PN10 and PN16.

  3. Leakage Class:

    • These valves provide 100% tightness even at fully differential pressure.

  4. Materials:

    • Body Material: Cast Iron (C.I.)
    • Disc Material: S.G. Iron (Spheroidal Graphite Iron)
    • Stem Material: Cast Iron (C.I.)
    • Body Liner/Seat Material: NBR (Nitrile), EPDM, VITON, SILICONE, PTFE
    • Shaft Bearing Material: PTFE

  5. Key Features:

    • Bi-directional zero leakage: These butterfly valves prevent any flow leakage in both directions.
    • ISO Pad for mounting: Allows easy installation of gear operators or actuators.
    • Double D drive: Minimizes play between the stem and disc for precise control.
    • Dual stem sealing: Ensures accurate sealing to prevent leaks.
    • Mounting between flanges: Can be installed between ASME flanges.
    • Tested and certified: Each valve undergoes testing with pneumatic and fluid (water) media.
    • Design Standards: Comply with ISO 5211, API 609, and ASME B16.5 150#.
    • Face to Face Dimension: Follows API 609 (CAT A) guidelines.
    • Operator Options: Hand lever, gear, or actuator can be used.
    • Leakage Class: Achieves 100% tightness even under full differential pressure.

These butterfly valves are reliable for flow control in various industrial applications, and their robust construction ensures durability and efficient performance.
