Product Description
Pneumatic stainless steel hard sealed butterfly valve
◇ Briefly describe
The ALD673H-16P series pneumatic hard seal butterfly valve adopts a three eccentric metal sealing structure for the valve body. The precision valve plate sealing surface is polished and organically combined with the three-dimensional eccentric sealing surface, which has the characteristics of high and low temperature resistance, high pressure resistance, and long service life. Widely used in industries such as metallurgy, chemical engineering, petroleum, combustible gases, and water supply and drainage.
