Custom processing brand Xiamen special type D673H Stainless steel double connection forms the folder structure in the form of three eccentric For media Water Pressure environment Pressure Operating temperature Room temperature Standard American Standard flow direction bidirectional drive manually D673H American standard three eccentric hard sealing butterfly valve Product Features: The first deviation from the sealing surface of the eccentric shaft eccentric shaft centerline of the second and third partial pipeline unique eccentric seat taper angle and the angle between the center of the valve centerline of the pipe, so that is the seat and seal Circle in the door completely out of the entire switching process. This structure is the use of a cam effect, and completely eliminates friction, in addition to possible wear and leakage. Zero leakage through the seal disc elastic plate to achieve. Elastic composite metal ring makes specialty valves with zero leakage sealing performance torque constant two-way valve to ensure zero leakage characteristics D673H American standard three eccentric hard sealing butterfly valve Product Introduction: Before each part of a valve assembly should be removed burrs, sharp hook assembly 2 After the completion of the valve rotating flexible smooth, there should be three card group phenomenon after the test shall be closed to ensure the sealing surface from damage during storage and transport 4 valves designed and manufactured in accordance with JB / T 8527 5 valve inspection and testing by JB / T9092 6 connecting flange length of the structure according to the provisions GB / T9113.1 valve according to the provisions of 7 GB / T12221 pressure valve 8 - temperatures should be consistent with GB / T 9124 ratings Company: Xiamen special double valve plant Ltd. mainly specializes in producing various kinds of steel or stainless steel valves, valve manufacturer with more than 20 years of experience, access to national invention patents, 17 international patents, hosted and participated in the preparation of national standards 31.
