Designed for effortless installation, Koenig Expanders and Check Valves offer operational simplicity and reliability. Featuring a mechanical one-piece design and requiring simple hole preparation, Expanders minimize waste in processes, machining, and the use of additional solvents and adhesives.

The installation of Koenig Expanders is characterized by repeatability, ease, and integrity, significantly reducing preparation time, large manned installation lines, and the need for supplementary machining and cleaning.

To ensure the utmost reliability of all Koenig flow control and hole sealing solutions, each batch undergoes rigorous performance testing with 100% inspection. With over 5 billion units installed worldwide, our failure rates remain below 1PPM. As safety-critical components, Koenig products are 100% traceable, providing peace of mind and assurance of quality and reliability.

Cost effective SEALING OF DRILLED HOLES

Koenig expanders utilize cutting-edge expander technology to achieve secure sealing of drilled holes without the need for any waste, adhesives, or solvents. Compared to traditional ball and screwed hole sealing methods, Koenig expanders require half as many pre-installation operations, streamlining the sealing process and saving valuable time.

With dedicated tooling and standardized solutions, there is no need for large production ancillary equipment and significant investment. This ensures a cost-effective and efficient solution for hole sealing, allowing for seamless integration into various production processes.

PUSH type EXPANDERS

Push type expanders, including Series MB and Series CV, are specifically designed to seal counterbored holes effectively. With the use of a setting tool, the ball is pressed into the serrated sleeve, creating a comprehensive metal-to-metal seal. Max. pressure of 450 Bar and sizes from 3 – 22 mm.

PULL type EXPANDERS

Series SK and Series LK expanders are specifically engineered to seal holes in challenging scenarios where access is limited, such as at angles or on different faces where the block cannot be moved. Unlike push type expanders, pull type expanders use a mandrel to insert the plug into the hole and do not require counterbores or secondary machining.

During installation, a setting tool is employed to pull the expander back into the hole, causing the plug to expand and tightly seal the drilled hole. These expanders are capable of withstanding maximum pressures of up to 500 Bar and are available in sizes ranging from 4 to 20 mm.

Utilizing handheld riveter-style tools, expanders can be set quickly, linking directly to progressive production or assembly lines, enhancing efficiency and productivity in manufacturing operations.

Reliable Fluid and Gas Control in High Pressure Environments

Koenig check valves and flow restrictors are engineered to deliver dependable and precise control of fluid and gas in high-pressure environments. Utilizing the same metal-to-metal sealing technology as Koenig Expanders, they effectively prevent side leakage and remain secure in high vibration environments.

RESTRICTORS

Koenig restrictors are designed to manage the flow of gas and fluid in deep-hole installations with precision and reliability. Constructed from 300 series stainless steel and with a one-piece mechanical design based on the expansion principle, they ensure secure operation and prevent side leakage.

CHECK VALVES

Koenig ball check valves offer precise flow control with zero leakage, ensuring reliable regulation of fluid flow even under extreme pressure conditions. Leveraging SFC Koenig expander technology, these valves provide consistent performance and durability in various applications. Available in a range of sizes and cracking pressures, with options for both reverse and forward designs, Koenig stainless steel check valves are versatile solutions for controlling fluid flow.
