Worldwide the KOENIG-expander® is the No. 1 solution for quick and reliable sealing of drilled holes. Extremely versatile and available in a variety of materials the KOENIG-expander® permanently resists even the most extreme loads and pressures. Originally designed for use in hydraulic assemblies, it is now well established in all industries as a component in engines, gearboxes and transmissions, suspensions and braking systems, as well as in steering and fuel injection systems. Thanks to the existing broad range of KOENIG-expanders® and the production of customer-specific sealing plugs, KVT offers the ideal sealing system for any application. The KOENIG-restrictor® is a reliable solution for tamper proof or interchangeable flow control and regulation.

MB & CV SERIES

This design, based on the tension/expansion concept, uses a ball as an expanding element and an expansion sleeve. Especially suitable for high pressure (MB and CV max up to 450 bar) and base materials with low to medium hardness.

LK SERIES

The LK Series KOENIG-expanders® are ideal for lower pressures (max 60 bar) and use the tension/expansion concept. After reaching the predetermined force, the expanding element automatically breaks off at the predetermined breaking point.

SK SERIES

The tension/expansion concept of the SK series causes breaking off of the expanding element after reaching the predetermined force. These are particularly suitable for use in light metals, high pressure applications (up to max 500 bar), and also for bore holes with a smoother surface finish.

LP SERIES

The press fit and anchoring concept of the LP series makes use of a conical press-in sleeve. During installation, this adapts to the bore, and the outer serration bites into the bore wall. Particularly suitable for lower pressures (max 60 bar).

HK SERIES

The HK series KOENIG-expanders® are specifically designed for use in hard materials. They use the tension/expansion concept and are suitable for very high pressures (up to max 350 bar).

FLOW CONTROL: RESTRICTORS

KOENIG-restrictors® are classified into threaded and expander type restrictors. Both styles manage flow control and are currently used in various applications such as consumer goods, robotics, agriculture equipment, and many fluid power and hydraulic applications.
