SUS316L Manual Welded Ball Diaphragm Valves High Temperature Water OEM
Premium SUS316L Stainless Steel Hygienic Construction The valve body is made of SUS316L stainless steel with internal electropolishing up to Ra≤0.4μm, no dead corners, fully compliant with FDA & 3-A sanitary standards, supporting CIP online cleaning and SIP high-temperature steam sterilization to avoid material contamination and bacterial growth.
Safe Isolation Diaphragm Sealing Design Adopts PTFE+EPDM composite diaphragm membrane, completely isolates the medium from the valve stem, effectively preventing leakage, medium backflow and cross-contamination. It can withstand operating temperature from -10℃ to 135℃, ideal for high-temperature purified water and sterile steam pipelines.
Reliable Butt Weld Connection Structure Standard butt welded end ensures seamless connection with stainless steel pipelines, featuring excellent tightness and stable pressure resistance, perfectly suited for high aseptic requirements scenarios such as pharmaceutical workshops, biotech laboratories and pure water systems.
Easy Manual Operation & Precise Flow Control Equipped with handwheel manual actuator with opening indicator, the valve can stay stably at any opening position to realize accurate flow regulation. Simple structure brings low failure rate and convenient daily maintenance.
Customizable OEM Service & Wide Application We support OEM customization including laser logo engraving, different diaphragm material options, special packaging and technical parameter adjustment. Widely applied in beverage, dairy, brewery, pharmaceutical, cosmetic and purified water industry sanitary piping systems.
