Bermad 350-3x3-P Series Plastic Double Chamber Filter Backwash Valves

The Bermad 350-3x3-P Series is a high-performance, plastic-bodied backwash valve designed for the automatic cleaning of filtration systems in irrigation and industrial applications. These double-chamber, hydraulically operated, diaphragm-actuated valves deliver reliable and efficient filter backflushing with minimal pressure loss and reduced wear.

Available in Angle (A) and Straight (G) flow configurations, the 350-P Series offers flexibility for integration into new or existing filter batteries. The dual-chamber design ensures rapid and positive valve actuation with low operating pressure, while the fully isolated diaphragm prevents exposure to dirty backwash water, extending valve lifespan and performance.

APPLICATIONS

• Automatic backwash of filter batteries
• Gravel, sand, disc, and screen filter systems
