Kenzong Automatic Backwash Valve Hydraulic Drive Diaphragm Control Valve for Irrigation Filter Systems, 2" 3" 4" Ports, 0.7-10 Bar, Prevents Clogs & Water Mixing
AUTOMATIC BACKWASH OPERATION: Hydraulically driven by pipeline pressure (0.7-10 bar), this valve automatically switches between filtration and backwash modes, eliminating manual effort and ensuring consistent filter cleanliness without external power
- EFFICIENT DIAPHRAGM DESIGN: Features a short-stroke diaphragm actuator that swiftly changes flow direction, closes the inlet during backwash to prevent overflow, and avoids mixing clean water with wastewater, maintaining system hygiene
- DURABLE & CORROSION-RESISTANT: Constructed from robust engineering plastics or reinforced polyamide, the valve withstands aggressive media, corrosion, and outdoor conditions, ensuring long-term reliability in water treatment, irrigation, and industrial applications
- EASY INSTALLATION & MAINTENANCE: Designed for simple integration into existing systems with BSP/NPT/VIC connections (2″, 3″, 4″ ports). Its modular design allows online inspection and servicing without full system shutdown, reducing downtime
- VERSATILE APPLICATIONS: Compatible with gravel filters, disc filters, and screen filters for automatic backwash systems. Suitable for agricultural irrigation, pool filtration, wastewater treatment, and industrial water recycling
The Kenzong Automatic Backwash Valve is a high-performance hydraulic control valve designed for fully automatic backwash filtration systems. Driven by pipeline pressure, it enables seamless bidirectional flow switching to automate filter cleaning without external power. Its diaphragm-driven actuator requires only a short stroke to smoothly redirect water flow, ensuring the inlet closes when the backwash port opens (and vice versa), effectively preventing filter overflow and mixing of clean water with wastewater. Crafted from durable, corrosion-resistant materials, this valve is ideal for irrigation, water treatment, and industrial filtration systems. With easy installation and minimal maintenance, it enhances system efficiency, reduces manual intervention, and prolongs filter lifespan.
