Stainless steel sanitary ptfe lined rubber pneumatic diaphragm valve
The Stainless Steel Sanitary PTFE-lined Rubber Pneumatic Diaphragm Valve is an automated valve designed for corrosive or high-purity fluids. Its PTFE-lined rubber diaphragm ensures leak-free operation, while the pneumatic actuator allows precise, hygienic flow control in food, pharmaceutical, and chemical systems
Working Principles
The Stainless Steel Sanitary PTFE-lined Rubber Pneumatic Diaphragm Valve operates using a pneumatic actuator to move a stem connected to a flexible PTFE-lined rubber diaphragm. When air pressure is applied, the actuator pushes the diaphragm downward to seal against the valve seat, stopping flow, or lifts it to open the passage. The PTFE lining provides excellent chemical resistance, protecting the valve body from corrosive or aggressive fluids, while the rubber ensures a tight, leak-free seal. This design isolates the process fluid from mechanical components, maintaining sanitary conditions. The valve delivers rapid, precise, and automated flow control, ideal for food, pharmaceutical, and chemical processing applications.
