Cast Steel Trunnion Mounted Ball Valve

Cast steel ball valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute standard API 608&API 6D British standard BS5351 and generally conform to American society of Mechanical Engineers standard ASME B1634 valves are available in a complete range of body/bonnet materials and trims.
Standard body/bonnet materials include nine grades of carbon, low temperature alloy steel, for special applications they can be supplied in other grades of ally and stainless steel, there's a full range of trim materials to match any service optional packing and gasket materials are available for a full ranges of service conditions.

    Detail introduction

    Cast Steel Trunnion Mounted Ball Valve
    A - Operating: Extended lever for easy operation. Also available with gearing, motor actuators, pneumatic or hydraulic actuators for more difficult services
    B - Body & bonnet: Split or 3-piece,split body& bonnet for 12 & small. Disassembles easily for repair or replacement of internal components.
    C - BORE: Full bore or reduced bore. Full-bore design provides exceptional flow control.
    D - End Connections: A choice of flanged RTJ flanged or butt welding end for piping flexibility.
    E - Packing: Std packing multiple v-teflon packing, combined with live loading, maintains packing compression under high-cycle and severe service applications. Graphite packing is used for high- temperature situation.
    F - AS: Anti statics. A metallic contact is always granted between ball and stem /body to discharge eventual statics build-up during service.
    G - DDB: Double block & bleed. The body cavity is isolated when the ball is in either fully closed or fully opened position, the medium entrapped in it can easily be bled to avoid over pressure.
    H - FS: fire safe designed to API607 or BS 6755 to grant their operation suitability in case of fire. Secondary metal-to metal seal acts as backup if primary seal is destroyed by fire. Valves ordered for compliance with API 607 will be provided with graphite packing and gaskets.
