Why Choose the SED Steripur 217.30?
Zero Dead Leg: Body design eliminates crevices, ensuring complete drainability and preventing bacterial growth – critical for sterile applications.
Low Maintenance: The diaphragm isolates the valve internals from the actuator, reducing wear and extending service intervals.
Full Traceability: Each valve is serialized and comes with material certificates (EN 10204 3.1) upon request.
Easy Integration: Compatible with standard piping systems; optional position sensors, solenoid valves, and control units for automation.
Customizable: Available with different diaphragm materials, surface finishes (Ra ≤ 0.6 μm or Ra ≤ 0.4 μm), and special end connections for OEM projects.
