Pressure relief valve SDD 910 limits the static pressure to a constant and maximal settled value by opening the outlet (to the discharge line) when the pressure is overriding. A diaphragm separates the mechanical parts body and the channel. All wetted parts are in plastics. The diaphragm and seat seal are in EPDM or FPM according to the model.
The SDD 910 valves may be used as pressure relief valves on dosing or volumetric pumping system:
• for keeping preset working pressure constant on the primary side
• for ensuring constant dosing quantities in conjunction with oscillating pumps
These equipment protection devices may be fitted in any position, in line, or on by-pass according to the application.
The top handle, faucet like, allows the operator to adjust the working pressure without tools. On request SDD 910 may be provided with a simple cover and adjustment may be done with a BTR key.
