Sophisticated processing equipment, sound detection equipment, a sound quality assurance system to ensure product quality and reliability. Japanese standard JIS butterfly Product description D43H flanged butterfly, D73H Japanese standard clip-on three-dimensional eccentric oblique cone valve seat seal, the disc seal with new sheet metal and elastomeric materials are laminated, fitted butterfly board seat match. Use disc swing compress the seal, so the sealing surface friction is small, with more features and more tightly shut off, so that reliable sealing, sealing surface is completely open to ensure disengagement, to ensure the sealing surface from damage. The structural characteristics of butterfly excludes other types of butterfly opened a bit but can not seal the shortcomings, and in high-Shu normal use, to overcome the shortcomings of other types of valves in use at high temperatures due to thermal expansion easily leak. Uses and Features Japanese standard butterfly valve is widely used in petroleum, chemical and industrial water treatment and environmental protection, high-rise buildings, water supply and drainage pipes. 1, using the three eccentric structure, reliable hermetic performance. 2. Ensure that the disc does not touch the open sealing seat, eliminating the sealing seat uneven load, extended service life. 3, to ensure reliable sealing performance, high temperature, wear resistance, corrosion resistance and other advantages.
