Product Name

OEM Wafer Butterfly Valve Body Casting

Custom Ductile Iron Butterfly Valve Body with Precision CNC Machining

Product Details

Designed for industrial flow control systems, this OEM wafer butterfly valve body serves as the primary pressure-bearing housing for butterfly valve assemblies. Manufactured through precision sand casting followed by CNC machining on critical sealing and mounting surfaces, it delivers excellent dimensional accuracy, stable sealing performance, and long-term structural strength in demanding service environments.

The one-piece casting features an integrated circular valve chamber with precision-machined internal sealing surfaces, allowing accurate installation of valve seats, discs, and valve shafts. Four surrounding mounting lugs support wafer-style installation between pipeline flanges, forming a compact and efficient valve structure for industrial piping systems.

Material options include ductile iron, grey cast iron, carbon steel, stainless steel, and other custom alloys upon request. All units are produced strictly according to customer drawings and technical specifications. Critical sealing faces, internal flow chambers, and shaft bearing seats can be CNC machined to ensure consistent assembly precision.

Our butterfly valve body castings are widely used in water treatment, HVAC, municipal water supply, industrial process piping, chemical processing, fire protection, power generation, and general industrial fluid control applications. We provide full OEM and ODM customization, including custom sizes, pressure ratings, flange standards, machining requirements, surface coatings, and material grades.

Strict quality control is carried out throughout casting, CNC machining, dimensional inspection, and final component testing. Each casting is manufactured for stable quality, good interchangeability, and reliable service life under continuous industrial operation.
