Product Description

 

TYPICAL APPLICATION

DFSHOU back-flushing control valve can be connected with gravel filter or disc filter into an automatic backwash filtrationsystem, 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 -  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 PP material;
• Unique cavity design of BDV series ensuring high water flow;
• With an easily dismantled driven system for convenient on production line checking and maintenance;
• Dual-chamber design of BDV series 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, meetingthe demands of small flows.
• With the application of dual chamber design, BDV series providing angular flow and direct flow options, and being
free of installation direction confinement;

How it works
Take the straight-through flow control valve as an example: when the policy filters the working state, the inlet and outlet are connected, and the water flow is moving forward. When the external pressure water[1] into the diaphragm control cavity[2], pressure increases,diaphragm [3] drive valve core assembly[4] up into the upper seat[5] , the inlet is closed strictly, at this time the sewage outlet and the outlet, the water flow back from the outlet to the sewage outlet into the backwash state. When the water in the control cavity is discharged, the pipe water pressure and spring elasticity[6]work together to bring the valve core [4]assembly back to the lower seat[7] of the sewage outlet, the sewage outlet is closed and strict, and the control valve retums to the filter mode.
