The TriVAX product family (photo) provides confidence through traceable, proven, transparent safety functions. Along with the company’s smart Partial Stroke Test (sPST) integrated into the valve actuator, these functions include a hydraulic-circuit safety system with high-quality components, as well as the flameproof encapsulated housing that fulfills requirements for operation in potentially explosive atmospheres (Ex protection according to ATEX II2GD Ex d IIB T4). Especially with expansive facilities or pipelines, where the butterfly valves are often miles apart, the valves can be controlled via a simple electrical signal. Thanks to integrated interfaces to standard fieldbuses (Profibus PA, HART, Foundation Fieldbus) and the 4–20-mA connection, the TriVAX can be integrated quickly into existing automation concepts. — Hoerbiger Ventilwerke GmbH & Co.
