All components protected in one housing

摘要

Automated control valves are the heart of every process system: they control pressurised liquid or gaseous substance flows and ensure that chemicals and gases reach the right location at the right time. The reliability of these key components is a main area of concern for ensuring efficient operation of the plants. As a result, the control valves must operate safely over many years in production environments that are at times subject to extreme conditions in terms of temperature, pollution, material stress and maximum availability. All of these are dependent upon high power density, combined with the simple integration of safety functions. While conventional valve actuators generally consist of entirely separate technologies-mechanics, electronics and hydra ulics-Hoerbigers's system combines all the components protected in a compact housing. "Tri" in Trivax denotes the three technologies -mechanics, electronics and hydraulics - that are blended, with "vax" being the acronym for valve actuator
