2 Inches Auto Backwash Valve/Plastic Valve for Desalination Sand Filter/Disc Filter

Basic Info.

Product Description

TYPICAL APPLICATIONThe Filter Backwash Hydraulic Valve is a compact 3-port valve, in a T configuration. It is double chambered,hydraulically operated, and diaphragm actuated. CDFS back-flushing control valve can be connected with gravel filter or disc filter into an automatic backwash filtration system, and it can also change the direction of flow in water supply. The control valve has 2 control chambers, which can be deformed into angular flow or direct flow through different spring assembly direction. The unique cavity design ensures large flow volume of water supply:Auto back-flushing filtrationg system - CDFS series back-flushing control valves can be built into an automatic backwash system with gravel medium filter or disc filter.Water supply system - Being used in the water supply pipelines to reroute the water flow into angle or straight flow direction.FEATURE & ADVANTAGE• Hydraulic drive diaphragm control valve;• Unique plastic spool assembly design with tight sealing and corrosion resistance;• Short stroke of valves stabilizing water flow and avoiding blend of clean and dirty water;• Corrosion-proof and long lasting material;• Unique cavity design ensuring high water flow;• With an easily dismantled driven system for convenient on production line checking and maintenance;• Dual-chamber design of valve with low-voltage drive to effectively protect the diaphragm;• With the possibility to install changeover joints in the drain of the direct flow valve, from 4 to 3, from 3 to 2, meeting the demands of small flows.• With the application of dual chamber design, the valve providing angular flow and direct flow options, and being free of installation direction confinement;
