Proportional Control Diaphragm Valve Description
Proportional Control Diaphragm Valve is specifically designed for precise fluid control in biopharmaceutical and high-purity process systems. Its full-drain, dead-zone-free design ensures complete discharge of media, preventing residue accumulation and maintaining system cleanliness.
All parts in contact with the medium are made from high-purity stainless steel and PTFE, making the valve ideal for applications with strict hygiene and contamination control requirements. The valve provides smooth and accurate flow regulation, enabling reliable process control in sensitive pipelines.
With its combination of high-purity materials, hygienic design, and precise proportional control, this valve is widely used in biopharmaceutical production, sterile liquid handling, and other high-cleanliness fluid systems.
