Zero leakage American Standard bellows globe valve


Specifically designed for various high-risk media. In addition to the packing seal, the valve stem incorporates a bellows, creating a dual-seal structure that effectively prevents leakage of hazardous media. Structurally, incorporating practical applications from domestic and international valve usage, the valve disc and seat sealing pair utilize highly corrosion-resistant PTFE and Stellite hard alloy. This configuration ensures stable sealing performance, safe and reliable operation, strong corrosion resistance, zero internal or external leakage, and effortless operation. Its key technical indicators—including sealing integrity, maintainability, and safety—meet the standards of world-renowned products, making it a viable replacement for imported alternatives.
