Vector 4-Bolt & 6-Bolt Closures

Vector 4-Bolt & 6-Bolt Closures

4-bolt Vector Techlok Closures 2”- 26”

4-Bolt Vector Techlok Closures offer reliable and robust sealing utilising many of the standard parts of the time-proven Techlok clamp connector system and Vector Techlok metal-to-metal sealring.

The simplicity of the design allows customers to use the pressure rating table published in the Vector  Techlok catalogue as a pressure rating guide. If pressure ratings above the catalogue ratings are required Freudenberg Oil & Gas Technologies can design a suitable closure for the application.

Closure working pressures of up to 15,000psi can be accommodated, with higher pressures by custom design. During opening the clamps are fully supported using a rail system which is suitable for horizontal and vertical configuration..

  • Size range

    • Supplied in sizes from 2-26”, the 4-bolt range covers most of the common launcher sizes.
    • Non-standard sizes can be accommodated on request.
    • Closures can be supplied for horizontal or vertical configuration with various options including opening hinges, davits or lifting eyes and safety interlocks.

  • Pressure energized sealing

    The Vector Techlok sealring offers several advantages over conventional gaskets types; for example, the gasket forces and seal diameter are minimal, enabling the load capacity of the components to be maximized, and the lack of a conventional flange gasket gives a gas-tight metal-to-metal seal.

  • 6-Bolt Vector Techlok Closures

    28”- 42”For Vector Techlok closures above 28” it is preferable to use a 3-piece 6-Bolt Vector Techlok design.

    The smaller clamp segments distribute the clamp force more evenly and are easier to handle on-site.

    6-bolt closures can be fitted with an integral pressure check bleed screw and interlock to facilitate safe opening.

  • Available options

    • Interlocks with integrated pressure check bleed screw.
    • Bleed valves and pressure gauges.
    • Hinges, davits or lift eyes for horizontal or vertical door opening.
    • Seal retention in the blind door to minimize the risk of seal damage when the door is opened during service.
    • Leadscrew torque reaction points, drive buckets or motorized options.
