Diaphragm valve The iris valve is mainly used for unloading bulk material bags, and the valve plays a role in cutting off material flow by tightening the neck of the material bag. Iris valves perform well in conveying explosive and brittle materials, but they are not suitable for handling high fluidity, abrasive materials, and systems that require frequent opening and closing. Performance Characteristics 1. Aperture type opening and closing, large flow diameter, no obstruction, fast unloading speed; 2. The opening can be adjusted, and the discharge flow can be adjusted arbitrarily; 3. Used for unloading bagged materials without touching them to avoid cross contamination; 4. Multiple power drive options; 5. It has a hygiene level configuration that meets GMP and FDA requirements.
