    features


    1. One-piece forged valve body

    The valve has a long service life because of over-sized wall thickness design.

    No external leakage point.


    2.valve body washer

    Inconel nickel alloy 718 triangular pressure self-tightening gasket is used to seal the valve and the valve cover.

    The triangular pressure self-tightening gasket could supply a variety of coatings to meet the requirement of working condition.

    Spring reinforced seal.

    Low contact stress.

    No leakage at valve body joint.



    3.High-strength support design

    The welded support is provided with a valve stem bush to prevent the valve stem from deviating laterally.
    ISO high precision actuator and installation platform.

    Any actuator can be installed.


    4.Ball and valve seat

    An interference self-tightening downstream seat is embedded and fixed inside the valve body; the broad sealing surface has reduced the stress on the sealing surface; and a good sealing effect is maintained during high cycling operation.

    Ball and valve seat polished and overlapped are ground to match one-to-one, with 100% sealing contact.


    With the double arc cut of the ball, it is possible to quickly release pressure and reduce velocity while the valve is opened, which prevents the damage to the valve from the high speed flushing of fluid while the valve is opened and closed.



    5.Valve seat spring

    Assisted by pipeline pressure, continuous thrust for sealing is provided between the ball and valve seat, and thus the sealing is well maintained.


    6.Valve rod and burden configuration

    One-piece valve rod.

    Live load.

    1/4 rotation and non-rising rod do not damage the packing.

    Graphite preparation against extrusion and packing ring made of Inconel nickel alloy wire.
