Two-way Diaphragm Valves
● Pneumatic Diaphragm Valve（stainless steel actuator、plastic actuator）
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.
