    Technical Features

    Main FeaturesBODY


    The TRUNNION BALL VALVES design hasbeen conceived with thetarget to grant to final usersthe following advantages: To permit an easy

    assembly and disassembly operation;

    To provide the valves with two independent floating seat rings ensuring the bidirectional tightness of the valve. The seat rings are spring loaded to achieve the required tightness even at very low pressure.

    To avoid any over pressure acting in the body cavity providing each seat ring performing the Single Piston Effect obtaining self relieving function.

    To easily insert in the seats resilient seal insert of every type of material as well as to assembly in the valve METAL TO METAL SEAL. On request the design

    permits to provide modified seat rings

    performing double piston effect. To accomodate

    easily special features as per costumerrequest.

    The TRUNNION SIDEENTRY are bolted bodyside outlet design to simplify assembly and fieldservice. Perfect sealing and fire safe features are granted by the double sealing action of 0-Rings and graphite gaskets in all static joints of the bodycomponents.

    The TRUNNION FULLYWELDED BODY DESIGNreduces the potential leakof bolted design. The bodywelded configuration allowfor a considerable reduction in weigt when the welded end version isselected. Also for this typeof valves the stem extension can be easily provided, making the valves
