Pressure relief valve SDD 910 protects a network of pipes in the event of overpressure that could lead to deterioration of the system. It limits the static pressure to a constant upstream pressure when the pressure is over the settled value.
All wet parts are of plastics. The diaphragm and seals are of EPDM or FPM according the model.

SDD 910 valves may be used as pressure relief valves on dosing or volumetric pumping systems.
The pressure relief valves are mounted in any position, or in line or as a bypass, according to requested operation.
They can also be used on injection stems with dosing pumps, avoiding the risk of siphoning, creating a constant back-pressure (adjustable on site).

As a standard supply, valves SDD 910 have a top handle for adjustment, which is self-locking.
