    Features & Benefits

    SK41 has a wide range of applications, minimal fluid resistance, and the packing is not easy to be destroyed. The sealing ring is made of elastic materials such as FEP, keeping zero leakage. It can be rapidly opened&shut with small torque, easily repaired.

    Flanged Cast Steel Ball Valve SK41

    One-piece cast handle, easy to operate, quick to open and close. The top flange under actuator can also be customized according to customer requirements.

    The gland effectively protects the internal packing, thus preventing the medium leaking out from the stem. Also, it can be opened and then the packing can be replaced in time to solve the problem of leakage from the stem.

    The stem is internally installed, whose shoulder and PTFE (or reinforced graphite) thrust pad prevent the stem from blowing out due to the sudden increase of pressure in the pipeline.

    It has good sealing performance with high precision grinding. Also, it can be hardened as required.

    Fluoroplastic seat can achieve complete sealing and zero leakage. The seat can be replaced, whose material can be selected according to the medium.

    Two-piece structure is convenient to replace parts such as ball and seat. Different materials can be selected according to working conditions.
