Parts and Material List :

Design

AVC ball valve are designed and 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 6D, British Standard BS 5351 and generally confirm to American Society of Mechanical Engieers Standard ASME 816.34. Valves are available in a complete range of body/bonnet materials and trims.

Applicable Standards

  • Steel Ball Valve, API 608 /AP| 6D
  • Steel Ball Valve, ISO 10434 / ISO 14313 Fire Durable, API 607
  • Steel Valve, ASME 516.34
  • Anti Static, API 608
  • Face to Face, API 6D
  • End Flanges, ASME 516.5
  • Buttwelding Ends, ASME 516.25 Inspection and Test, API 598 /AP| 6D

Range of Materials

Standard body/cap materials include Carbon Steel Low Alloy and stainless steels. For special applications they can supplied in other grades of Alloy 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 range of service conditions.

Design Description

  • Full port design

  • Floating ball type
  • Blow-out proof stem
  • Fire durable construction
  • Anti static device
  • ISO 5211 Mounting pad
  • Flanged 0r buttwelding ends
  • Available with Worm Gear operator

  • Operating

    Extended lever for easy operation. Also available with gearing, motor actuators, pneumatic or hydraulic actuators for more difficult services.

  • Bore

    Full bore or reduce bore. Full bore design provides exceptional flow control.

  • End Connections

    A choice of flanged, RTJ flange or butt-welding end for piping flexibility.

  • Body & Cap

    Split or 2-piece, split body & cap for 12" & small. Disassembies easily for repair or replacement of internal components.

  • Packing

    STD packing multiple V-PTFE packing, combined with live loading, maintains packing compression under high-cycle and severe service applications. Graphite packing use suitable for high temperature.

  • BPS

    Blow-out proof stem. A pressure safe stern shoulder design that protects against failure under excess pressure.

  • AS

    Anti Static. A metallic contact is always granted between ball and .stem / body to discharge eventual statics build-up during serwce.

  • FD

    Fire durable. Designed to API 607 or BS 6755 to grant their operation suitability on 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 gasket.
