Markus KRÖLL

Title: Markus Kröll: Inventor of Valve Actuator Safety Components

Introduction

Markus Kröll is an inventor based in Dattenberg, Germany, whose patent work focuses on components for valve actuators. He is associated with Watts Regulator Company and holds 2 patents.

Latest Patents

Kröll’s recent inventions address torque protection and secure assembly in valve actuator systems.

“Torque Limiter Coupling Assembly for Valve Actuators” describes a coupling designed to shield a valve or actuator from abnormally high torque. During normal operation, the assembly transfers driving torque from the actuator to the valve shaft. If counter-torque exceeds a set threshold, the actuator coupling rotates freely relative to the valve shaft coupling, directing the driving torque to a biasing element instead.

“Retention Clip for a Valve Shaft Adapter” describes a clip that secures an adapter collar to a valve actuator. Its spring-clip arms include lugs that can be gripped with pliers, allowing the clip ends to retract through holes in the collar. This design supports both installation and removal of the adapter collar.

Career Highlights

Kröll’s patent portfolio reflects practical engineering aimed at improving the safety, retention, and serviceability of valve actuator assemblies. His inventions address both protection against excessive operating torque and reliable attachment of valve components.

Collaborations

Kröll is associated with Watts Regulator Company, a company whose work includes products and systems for water regulation and control. His patented designs relate to valve actuator components.

Conclusion

Markus Kröll’s inventions focus on making valve actuator assemblies safer and easier to maintain through torque-limiting and retention mechanisms.
