ADCA. 2. PRODUCT INFORMATION The ADCA RP45 series pressure reducing valves are single seated, bellows sealed proportional controllers that operate without auxiliary energy. These are used in industrial applications to maintain the pressure downstream of the valve within acceptable limits of the adjusted set point. - Page 9 To avoid this, the valve can be installed with the fluid direction against the plug under certain conditions. However, it is suggested to consult VALSTEAM ADCA before installing the valve with liquids. Alternative models are also available for reducing service in liquid applications.
