- Protection of piping systems
- Maintaining upstream pressure
- Injection lances for dosing pumps

DD 910 pressure relief valves are designed to protect piping systems against overpressure and to maintain a constant upstream pressure, even in the event of pressure variations. Ideal for use with pumps, these versatile valves can be installed inline or in bypass, depending on requirements and in any position.

Manufactured with high-quality plastic materials for all wetted parts, SDD 910 valves feature diaphragms and seals available in EPDM or FPM to suit various applications. They are also effective as injection lances on dosing pumps, eliminating siphoning risks thanks to an adjustable and constant back pressure.

Equipped with an adjustment knob with automatic locking, SDD 910 valves simplify the adjustment process without requiring additional tools or wrenches.
