    D341X soft seal butterfly valve
    D341X soft seal butterfly valve

    D341X soft seal butterfly valve works:

    The center of rotation of the butterfly plate (that is, the center of the valve stem) is located on the center line of the valve body and the cross section of the sealing surface of the butterfly plate. The butterfly plate can be rotated 90 degrees to complete the opening and closing. The seat is made of synthetic rubber. When closed, the outer sealing surface of the butterfly plate squeezes the synthetic rubber valve seat, causing the valve seat to elastically deform to form an elastic force as a sealing specific pressure to ensure the seal of the butterfly valve.
    D341X Soft Seal Butterfly Valve Features:
    ★ The driving mode can be selected from manual, electric or pneumatic.
    ☆ The flow characteristics are straight, and the adjustment performance is good.
    ◆ The seal can be replaced, and the seal can reach the two-way seal reliably.
    ◇ Compact and lightweight, easy to disassemble and maintain, and can be installed in any position.
    ■ Simple and compact structure, small operating torque, 90 ° turning and quick opening.
    □ The butterfly board can be spray-coated according to user requirements, such as nylon or PTFE.
    ▲ The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes possible internal leakage points.
    △ The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and prolongs the service life of the valve. It still maintains zero leakage when it is opened and closed under pressure for more than 50,000 times.
