Detail Information

Electric wafer hard seal valve has the advantages of long service life and energy conservation. The structure utilizes three dimensional eccentricity and seat uses multiple level structure to ensure sealing. The valve, consisting of body, disc, seat, valve stem, gear and other components, is widely used for pipe line in metallurgy, power, petroleum and other industries.

Characteristics:

1. Small torque, convenience.

2. Three dimensional eccentricity structure, having excellent seal

3. High pressure resistance, corrosion resistance, wearing resistance, long service life

Actuator

1. Powerful function: intelligence, regulation, switch

2. Small volume: compared with same products, volume is smaller by 35%.

3. Convenient utilization: uniphase source easy for wring; unique structure easy for observation.

4. Protector: double spacing, over temperature protection, overload protection.

5. Intelligent numerical control
