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..
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.
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.
