    Product advantages:

    1.wesdom patent products, patent certification.

    The product side flanges comply with national, German, Russian, American, British and Japanese standards and other domestic and international standards for multiple pressures, easy connection and wide adaptability, which can reduce the type of purchase and stock.

    2.The thickness of valve body wall is up to standard.

    The valve body wall thickness meets the requirement of GB 26640, the thickness is up to the standard, and the pressure strength is guaranteed.

    3.Valve body valve plate is made of QT450-10 material

    Valve body valve plate is made of qt450-10 material with spheroidization rate above grade 3, tensile strength of 450Mpa and elongation of >10%.

    4.Good sealing and long service life of valve seat

    The valve seat is made of imported rubber material, with more than 50% rubber content; Elongation at break greater than 350%, valve sealing reliable, long life.

    5.Soft back with wide side seat

    Soft backrest wide side valve seat, is advantageous to the valve installation, in the pipeline and flange boss contact surface is wide, sealing performance is reliable. Life is longer than a hard back. And easy to remove and replace.

    Standard Test :

    Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.

    Seat Test: 1.1 times the working pressure with water.

    Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.

    Special Test: On request, any other test can be carried out according to special instruction by client.
