Overview
The Mueller Steam 8PEC CO 791 duplex strainer Class 150 is engineered for continuous-duty filtration in industrial piping systems. This Class 150 unit features a welded carbon steel body (WCB) rated for 150 psig, making it suitable for steam, water, and other process fluids in demanding applications. The duplex design allows alternating basket operation, eliminating the need to shut down flow for basket cleaning and maintenance.
Key Features
- Duplex (dual-basket) configuration enables one basket to be serviced while the other remains in service
- Welded carbon steel body (WCB) construction for superior durability and corrosion resistance
- Class 150 pressure rating (150 psig) suitable for medium to high-pressure applications
- Two-inch nominal connection size for standard industrial piping
- Low-pressure drop design minimizes energy consumption in continuous-duty service
- Replaceable basket elements for easy maintenance and cost-effective operation
