APPLICATION AND FITTING
Pressure relief valves SDD 912 limits the static pressure to a constant and maximal settled value by opening the outlet (to the discharge line) when the pressure is overriding. The right angle concept allows small dimensions with a reduced weight for easiest fitting on line than any conventional in-line straight pressure relief valve. All wetted parts are in plastics; without any metallic parts exposed to the atmosphere it allows a location in corroding vapours.
The SDD 912 valves may be used as pressure relief valves on volumetric pumping system. These equipment protection devices may be fitted in any position, in line, or on by-pass according to the application.
