1.Use of double-chamber diaphragm drive mechanism instead of piston type, which is featured by no moving abrasion, no water leakage resulted from sundries, not sensitive to sludge deposition, no need of lubrication and no production of mechanical abrasion

2. Outstanding performance, rubber lined disc, inclined placket of valve seat, and no deposition of sludge and sundries.

3. Low drive medium pressure, no need of a pressurizing pump or air compressor, use of liquid control selector valve under integrated control, and easy control and operation

4.Lasting durability and long service life.
Nominal Pressure:0.6MPa,1.0MPa
