Body & Disc Material: Premium SS316 (CF8M) / SS316L
Connection Type: Wafer style (Fits ANSI Class 150, PN10, PN16, JIS 10K flanges)
Seat Materials: PTFE (Teflon), RPTFE, EPDM, NBR, or Metal-to-Metal
Design Standards: API 609, BS EN 593, ISO 5752 (Face-to-Face)
Operation Options: Lever Handle, Manual Gear Operator, Pneumatic Actuator, or Electric Actuator
Testing & Inspection: API 598 / ISO 5208 (100% Pressure & Leak Testing)
Superior Corrosion Resistance: Built with genuine Grade 316 stainless steel, every china dn100 ss316 wafer butterfly valve provides exceptional long-term durability in corrosive process pipelines, chemical processing plants, and seawater systems.
Compact & Lightweight Wafer Design: The short face-to-face dimension reduces installation space and pipeline stress, lowering overall shipping and labor costs for large-scale engineering projects.
Zero-Leakage Sealing: Precision-machined disc edges combined with resilient seat options guarantee bi-directional bubble-tight shutoff under maximum working pressure.
Universal Flange Compatibility: Our wafer-style body features multi-standard alignment holes, allowing seamless integration into global piping systems without modifying existing flanges.
As an established China dn100 ss316 wafer butterfly valve manufacturer, we combine rigorous ISO 9001 quality control with flexible OEM/ODM manufacturing capabilities. Whether you are a global valve distributor, EPC contractor, or system integrator, we provide complete engineering support, including CAD/3D dimension drawings, Material Test Certificates (MTC EN10204 3.1), and third-party inspection reports (SGS/TÜV).
