P 3 Diaphragm

Pentair Südmo’s revolutionary P 3 material was designed to eliminate the problems associated with traditional aseptic rising stem valves. Our P 3 material is resistant to high pressures, high temperatures and aggressive chemicals. Customers who have retro-fitted this material into their systems have experienced significantly extended service life and reduced maintenance without changes to their process.

P 3 has excellent cleaning properties and outstanding performance even under the most difficult operating conditions, ensuring that the system remains sterile. With our PEEK stem option, product doesn’t burn on to the hot stems because the PEEK material reduces the thermal transfer from the sterilization medium to the finished product.

P 3 is available in the SVP Select Valve series and as a kit that is 100% retro-fittable on existing Pentair Südmo valves. Now is the time to take advantage of this groundbreaking material and start reaping the benefits from reduced plant downtime and longer maintenance intervals.
