Bdv080s Straight Back Flush Low Pressure Control Valve

BDV080S Straight Back Flush Low Pressure Control Valve

The BDV series back-flushing control valves are 3-way, 2-chamber hydraulic drive diaphragm valves designed for low-pressure sealing and smooth flow transition. These valves can be integrated with gravel or disc filters to create an automatic backwash filtration system, and they also allow for flow direction changes in water supply systems. The dual-control chamber design enables the valve to switch between angular and straight flow based on spring assembly orientation. The unique cavity design ensures a high flow capacity, making it ideal for efficient water distribution.

Typical Applications

Auto Back-Flushing Filtration System:

The BDV series can be used in conjunction with gravel or disc filters to form an automated backwashing system, ensuring clean and continuous water flow without manual intervention.

Water Supply Systems:

These valves are suitable for water supply pipelines where flow direction needs to be changed to either angular or straight flow, offering flexibility in system design.

Key Features

1. Hydraulic-driven diaphragm control valve for reliable performance;

2. Unique plastic spool assembly with tight sealing and corrosion resistance;

3. Short stroke operation stabilizes water flow and prevents mixing of clean and dirty water;

4. Corrosion-resistant PP material ensures long service life;

5. Easy-to-dismantle drive system for convenient maintenance and inspection;

6. Dual-chamber design with low-voltage drive to protect the diaphragm;

7. Dual-chamber design allows for both angular and straight flow options without installation restrictions;

8. Unique cavity design maximizes water flow efficiency;

9. Compatible with changeover joints in the drain port, allowing flow adjustments from 4 to 3, 3 to 2, meeting small flow requirements.

How It Works?

In the normal filtering mode, the inlet and outlet are connected, allowing water to flow straight through. When pressurized water enters the diaphragm control chamber, the diaphragm lifts the spool assembly to seal the inlet and connect the sewage outlet, initiating the backwash cycle. Once the pressure is released, the spool returns to its original position, sealing the outlet and resuming the filtration process.
