TYPICAL APPLICATIONS
The BDV series back-flushing control valve is designed to integrate with gravel or disc filters to create an automatic backwash filtration system. It can also redirect the flow of water in irrigation systems. The valve features two control chambers, allowing it to switch between angular and straight flow configurations based on the spring assembly orientation. Its unique cavity design ensures a large flow capacity, making it ideal for various applications.
Automatic Filtration System: The BDV series valves are used in conjunction with gravel or disc filters to build an efficient, self-cleaning filtration system.
Water Supply Systems: These valves are commonly used in pipelines to change the direction of water flow, either at an angle or straight, depending on the requirement.
FEATURES & BENEFITS
• Hydraulic-driven diaphragm control valve
• Unique plastic spool assembly for tight sealing and corrosion resistance
• Short stroke design stabilizes water flow and prevents mixing of clean and dirty water
• Corrosion-resistant PP material for long-lasting performance
• Advanced cavity design enhances water flow efficiency
• Easy-to-dismantle drive system for simple maintenance and inspection
• Dual-chamber design with low-voltage operation to protect the diaphragm
• Optional changeover joints allow flow adjustment from 4 to 3, or 3 to 2, suitable for smaller flow requirements
• Offers both angular and straight flow options without installation restrictions
