Fully automatic backwash filtration system dedicated hydraulic control valve, driven by the pressure of the pipeline system, can automatically carry out two-way switching, to achieve automatic backwash filter. The simple structure and high reliability ensure long-term, stable operation without maintenance. The diaphragm drive structure requires only a short stroke to smoothly change the flow of water, close the inlet when the backwash port is open, and vice versa. Avoid filter overflows or water mixing with wastewater.

Features:
Simple structure, easy installation, save investment in ultra-strong hydraulic performance, work conversion frictionless high reliability, moving parts run smoothly anti-chemical corrosion materials, suitable for a variety of media water flow rapid, high backflushing efficiency.
- Hydraulically drive the diaphragm control valve
- Unique plastic valve core assembly design, strong sealing, corrosion resistance
- The valve travel is short, the flow changes smoothly and smoothly, avoiding the mixing of clean water and sewage
- Valve body PA material design, corrosion resistance, acid and alkali resistance, long service life
- The drive can be removed independently for easy on-line inspection and maintenance
Parameters:
Standard pressure level: 10 kgf/cm²
Minimum operating pressure: 1.0 kgf/cm²
3”-35 square/hour, plastic bayonet
Application
The backflush valve is applied to an automatic backflushing filtration system with at least two side-by-side filtration units, i.e. during the backflushing process, clean water filtered by one filter unit is used as flushing water from another filtration unit.
When the hydraulic signal from the controller is received, the backflush valve changes the flow of water: close the inlet, open the drain, filter the clean water through the other filtration unit into the unit for flushing, and discharge the flushing water through the drain.
