Introduction
Sing-Tao® Diaphragm Valve is designed to shut off, divert, or regulate fluid flow in hygienic, high-purity, and sterile pipelines. Featuring a compact and lightweight structure, it supports manual or pneumatic actuation with easy configuration to meet virtually any process requirement – including applications with microbial control demands such as food & dairy, biopharmaceutical industries, and other critical hygiene-sensitive operations.
Design Advantages and Features
Sing-Tao® Diaphragm Valves’ core advantage lies in their stagnation-free or dead-leg-free valve body structure, enabling complete self-draining. Compatible with CIP (Clean-in-Place) and SIP (Sterilize-in-Place) processes, they ensure rapid evacuation of residual media to prevent microbial growth and impurity retention. Customizable multi-channel configurations achieve minimal dead legs while maximizing drainage efficiency and cleanability.

Features
● Designed for high-purity applications in food & beverage, pharmaceutical, and bioengineering industries.
● Core advantage: The diaphragm completely isolates the medium from actuation components, eliminating contamination risks.
● Medium-wetted materials are non-leaching, non-toxic, high-temperature resistant, and corrosion-resistant.
● Suitable for process pipelines requiring high sanitary standards.
● Compatible with solenoid valves or positioners for precise flow regulation capabilities.

The combined diaphragm valve is welded together by the valve body of the straight diaphragm valve as required specifically by the customer. The different combination azimuth and angles are adopted to reduce the length of the dead angle pipe on the pipeline, but it shall conform to the requirementsof L/D≤3 in principle.
