square flange valve

Upper and lower round flanges,positive or negative pressure conveying rotary valve ,rotary airlock feeder
 
Rotary valve is often used in capsule.
Rotary valve is applied to discharge powder or granular material either in positive air pressure or in negative air pressure of pneumatic conveying system.Also it is a necessary device for ventilation and move dust systems.Rotary valve is especially suitable for separating and discharging powder and small particulate matter in the process of positive and negative suction.
Rotary airlock feeders have wide application in industry wherever dry free-flowing powers,granules,crystals,or pellets are used. Rotary valve is commonly used in industrial and agricultural applications as a component in a bulk or specialty material handing system.Rotors have large vanes cast or welded on and are typically driven by small internal combusyion enginesor electric motors.
 

How do we control the quality of machining

In production, we demand not only quantity but also quality.

How do we ensure finished product quality (FQC inspection)

1. Visual Inspection

2. Material Grade Measurement

3. Dimension Inspection

4. Roughness Detection

5. Roughness Detection

6. Leakage Test

*Note: If match special flange,please let us know before production.
