Hengke supplies stainless steel butterfly valve discs made by investment casting and precision machining. Disc profiles, stem connections and sealing edges are adapted to customer drawings for industrial or sanitary valve assemblies with specified operating conditions.
Review the disc profile, stem connection, sealing edge and movement clearance against the valve assembly drawing. Machining and polishing requirements should identify the seating surface, allowable edge condition and finish needed by the specified sealing arrangement.
Available verification includes material documentation, dimensional reports and surface examination. Hardness checks, nondestructive testing or component-specific inspection can be agreed against the approved drawing and purchase specification.
