The following features characterize the value and the price-performance ratio of the valves from STÖHR ARMATUREN:
Use of solid material
All pressure-bearing parts are made of solid material – no castings or other manufacturing processes for raw materials are used, to avoid cold leaks at even the lowest cryogenic temperatures.
Bellows sealing achieves high tightness to environment of the first spindle seal
Almost all valve series from STÖHR ARMATUREN are bellow sealed to outside. The highest values for leak-tightness at 1x10E-8 mbar*l/sec to the outside can be achieved, equal to the volume of a drop of water within three years.
Fulfillment of the required industry standards according to European regulations
As a European manufacturer, we comply primarily with European rules. If you require another standard, we will consider your request on a case-by-case basis.
Low maintenance, low spare parts requirement, and low lifecycle costs
Due to our design principles and the high quality of the materials used, maintenance and spare parts requirements for all STÖHR ARMATUREN valves are comparably low. Very low failure rates and long service life results in low lifecycle costs.
