The metal seated triple offset butterfly valve uses butterfly disc as the closing part to realize the operation of the valve through the rotation of the disc around the valve shaft. Large size valves can be made . Mainly used for cutting off the fluid ,this range of product is applicable for water,oil,gas and other corrosive substance with the temperature less than 425ºC.
BENEFITS
1.Manufactured with three-eccentric structure, the metal sealed butterfly valve can be tightly closed. When opened,the sealing surface can be completely separated from the medium,which protects the sealing surface from being damaged.
2.The valve seat is processed on the body of the three-eccentric butterfly valve directly, reducing the direct contact between the valve seat and the medium. So the erosion to the valve seat is reduced and its service life is prolonged.
3.The contact angle of the valve is larger than the degree of taper scope. So the blocking of the butterfly valve during operation can be avoided.
4.Made of overlaying alloy steel or satellite hard alloy, the sealing surface of the butterfly valve has longer service life due to the outstanding abrasion resistance.
