differential pressure/time 10 stations controller for automatic filter

back-flushing control valves are 3-way & 2-chamber hydraulic drive diaphragm control valves with low pressure seal and smooth flow change.

TYPICAL APPLICATION
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 - 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:

1. Adopt high degree pottery, corrosion proof, perfect sealing

2. No water flows out in the drain line when in washing position with signal tank valve

3. Adopt LED screen, the color move to flicker during service, Otherwise the control valve is during washing

4. Keyboard lockout function: the screen will automatically lock if no operate more than one minute

5. Indication and parameter saved after power off

6. The interval back-wash time can be set (suitable for F68,69),multiple operating in service with one time
backwash. Saving salt and water.
7. Bypass available for valves

8. It could set repeat-washing

9. Signal port control output

10. Remote handle input signal

PRODUCT DESCRIPTION

THREE-WAY BACKFLUSHING CONTROL VALVE

the valve is double tune deconsruction,drve by hydraulic pressure.it is installed in the filter systerm, in order to realize the backflushing by control the water flow.

Design and selection of models
1. Water quality classification

A.: Water of good quality: city tap water, well water from stable aquifer.

B.: Water of general quality: cooled circulating water, surface water treated by sedimentation, and drained water treated by effective deposition and completely biological treatment.

C.: Water of relatively poor quality: groundwater from aquifer of poor quality, drained water treated by effective deposition but with poor biological treatment, and surface water with enormous microbes.

D. The worst quality: well water with rich iron and manganese elements, surface water affected by flooding and without sedimentation, and drained water without precipitation and biological treatment.

Different water qualities have different influences on the filter's operation period, so in general it is better to keep the system's backwash intervals no less than 1 hour.
