What is double offset butterfly valve?

Double offset butterfly valve is popularly known as a high-performance butterfly valve and has two offsets from the valve body's center: The shaft axis is offset from the disc's seat and body seal's centerline, and. The shaft axis is eccentric to the pipeline's/valve's center line.

The balance of this valve is in the stem placed behind the circular disc. It allows the disc to self-adjust to the center, ensuring tight sealing. Even when the valve is fully opened, the valve does not touch the soft seat, ensuring a longer service life.

• • 1. Heavy body,the thickness of valve body meets the requirements of GB26640 to ensure bearing strength.
    2. epoxy coating, spray thickness up to 250um.Strong adhesion.
    3. import EPDM rubber material. 50 percent rubber content, Stable and small torque, zero leakage after open and close more than 10000 times .
    4. Wider rubber seat,wider contact surface with flange.better sealing performance.
    5. Each valve will be wasted by ultrasonic cleaner before packing, Remove dirt and granularities from valve body. Prevent the valve itself from coordinating the media in pipes.
