Our Class 150 Duplex Strainers are engineered to ensure uninterrupted flow, minimal pressure drop, and easy maintenance. Designed for flange connection systems conforming to ASME standards, these strainers are ideal for removing debris from pipelines without shutting down operations.

What is a Duplex Strainer – Class 150?

A Duplex Strainer is a dual-chamber filtration device designed to allow continuous flow even during maintenance. Unlike a Y Strainer or Basket Strainer, a duplex system consists of two strainers connected via a changeover valve arrangement. While one chamber operates, the other can be cleaned without interrupting the process.

The “Class 150” rating refers to the pressure class as per ASME B16.5 standards, typically suitable for low to moderate pressure industrial applications. These strainers are widely used in systems handling water, oil, steam, chemicals, and process fluids.
