空气驱动气动薄片金属阀座Butterfly Valve

Thepneumatic wafer metal seated butterfly valveadopts “U” type stainless steel sealing valve.And thispneumatic actuated wafer butterfly valvehas the characteristics of high temperature resistance,high pressure resistance and low temperature resistance. Therefore,theair actuated wafer butterfly valveis widely used for heating supply,water supply, gas supply with medium temperature ≤500 °C.

The Characteristics of Pneumatic Wafer Metal Seated Butterfly Valve:

1. The pneumatic wafer metal seated butterfly valve has the advantages of simple structure,compactness,light weight,easy installation & disassembly,and convenient maintenance;
2. The butterfly valve adopts stainless steel “U” type sealing ring,which has certain elasticity and has excellent sealing performance under high temperature and low temperature conditions;
3. The operation is flexible,convenient,labor-saving,free from the influence of medium pressure, and the sealing performance is reliable;
4. This pneumatic actuated wafer butterfly valve has high temperature resistance,low temperature resistance,corrosion resistance.
