ADVANTAGES

Superior Flow Dynamics: The extra-wide body design ensures maximum permeability, delivering a powerful and effective backwash with minimal flow restriction.

Heavy-Duty Ductile Iron Body: Constructed from high-grade GGG40 ductile cast iron, these valves offer exceptional strength, impact resistance, and long-term durability, even in the most demanding conditions.

Optimized Energy Efficiency: Engineered for superior hydraulics, our valves minimize pressure loss across the system. This reduces the load on your pumps, leading to significant energy savings and lower operational costs.

Simplified Installation & Maintenance: Designed with a user-friendly structure and a minimal number of accessories, these valves drastically reduce installation time and make routine maintenance quick, easy, and cost-effective.

WORKING PRINCIPLE

The primary function of the backwash valve is to reverse the flow of water to effectively clean the filter. Upon receiving a backwash signal, the valve automatically reconfigures the flow path: it shuts off the incoming contaminated water while simultaneously opening a discharge line. This allows clean, filtered water from the rest of the system to enter the filter backward, forcefully dislodging trapped particles and flushing them out through the newly opened drain. This cycle efficiently restores the filter's performance before the valve returns to its normal filtration position.
