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.
