    Product details

    The biggest feature of the Taitubv Five eccentric butterfly valve is that the sealing structure is fundamentally changed. It is no longer a positional seal, but a torsion seal. That is, it does not rely on the elastic deformation of the valve seat, but completely relies on the contact surface pressure of the valve seat to achieve the sealing effect, so the problem of zero leakage of the butterfly valve metal seat is solved in one fell swoop. The design of the sealing angle solves the problem that the medium pressure acts on the sealing surface when the medium flows in the forward and reverse directions, and the contact surface pressure plus part of the medium pressure acts on the sealing surface to solve the high pressure resistance.


    Design Feature+

    1.Full metal sealing design, carbide alloy spray is available on sealing ring and valve seat.

    2.Sealing set can be replaced at site, which reduces the cost of maintenance.

    3.Bi-directional seal, zero leakage. (Level VI leakage)

    4.Fixed bottom stem makes sure of higher stiffness. It is able to shorten the distance where stem is inserted into the disc, and reduces the flow resistance.

    5.The design of pin-free anti-blow out upper stem and double stem structure solves the problem of inconsistent heat expansion between stem, disc and valve body.

    6.The double stem design comes with less flow resistance and lower energy cost.

    7.Dustproof structure for upper and lower bearing, extra spiral groove anti-crystallization can be applied.

    8.API standard: Anti-blow out stem, diameter of actuating position is 10% smaller than pressure undertaking position in the disc, which prevent from blow out caused by inner fracture.

    9.Valve stem and disc is connected by spline with uniform pressure, no risk of cutting pin and easy to disassemble.

    Valve stem and actuator is connected by spline with uniform pressure, no risk of cutting pin and easy to disassemble.

    Constant pressure packing mechanism with butterfly spring, which can automatically compensate packing loss and prevent leakage of medium.

    10. The whole valve can be completely disassembled and reassembled at the site, that is, each component can be repaired and replaced on site, which reduces the long-term use cost of the product.
