THIES Safety Valves

Maximum blow-off rate due to low flow losses -

This was the principle governing the development of the THIES High-efficiency Safety Valves.

 

Special research led to the development of a simple construction of the flow passages leading to optimum efficiency and performance.



High functional and operational reliability due to a very simple configuration. Operation description
