Cv Values & Pressure Drops for Angle-Line Strainers Cv values or the provided pressure drop tables can be used to estimate the pressure drop across a strainer at a given flow rate. Cv values are for water at 70 °F. Contact Sani-Matic for inquiries on pressure drops for fluids with other viscosities.

NOTE: Cv values and charted pressure drops can be used for perforated, wedgewire, and perforated with mesh overlays or filter tubes. The clean pressure drop is minimally impacted by the element configuration in most cases. For worst-case calculations, add 20% to the calculated pressure drop.
