Pressure Relief Valves - ND 10 to ND 25 SDD 911

A pressure relief valve SDD 911 limits the static pressure to a constant and maximal settled value by opening the outlet (to the discharge line) when the pressure is overriding. An EPDM diaphragm, PTFE coated, separates the mechanical parts body and the channel. All wetted parts are in plastics. The seat seal is in EPDM or FPM according to the model and connections.

Without any metallic parts exposed to the atmosphere it allows a location in corroding vapours. The SDD 911 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.
