RV Series Inline Bypass Valves
Ebsray® Inline Bypass/Pressure Relief Valves specifically designed for a wide variety of industrial services. These valves feature an easily adjustable differential pressure setting that provides accurate and repeatable performance. This enables full pump flow while maintaining controlled preset maximum pressure. ATEX compliant, these valves meet Australian and other international standards and codes. Available models include the RV18 (1 in) and RV19 (1.5 in).
