KOENIG-EXPANDER® – BEST-IN-CLASS SOLUTIONS AND SERVICES
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 sealingsystem for any application. The KOENIG-restrictor® is a reliable solution for tamper proof or interchangeable flow control and regulation.
Sealing technology
Push-type expanders
MB SERIES
Pressure to 450 bar
Expansion and anchorage of sleeve in hole wall is achieved by pressing the ball into the sleeve. The MB series plugs are designed for use in base materials of both low to high hardness (up to 450 bar pressure).
CV SERIES
Pressure to 450 bar
The CV Expander plugs are available in different materials and surface treatments. The CV plugs are available in metric as well as Inch sizes. Expansion and anchorage of sleeve in hole wall is achieved by pressing the ball into the sleeve.
Pull-type expanders
LK SERIES
Pressure to 60 bar
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.
HK SERIES
Pressure to 350 bar
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).
SK SERIES
Pressure to 500 bar
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.
Low-pressure expanders
LP SERIES
Pressure to 60 bar
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).
Restrictors
RE SERIES
An expansion restrictor functions according to the push-expansion method. Expansion restrictors, which inhibit flow, are available in metric and inch sizes. Expansion restrictors are used in numerous diverse applications.
RT SERIES
The threaded Restrictors are conveniently available in various sizes. Restrictors are currently used in numerous diverse applications such as mobile fluid power, automotive, medical, agriculture, construction, marine and aerospace.
