Stainless steel positioning micro-control proportional regulating flange diaphragm valve
The Stainless Steel Positioning Micro-Control Proportional Regulating Flange Diaphragm Valve is a sanitary precision valve with a diaphragm structure. It provides accurate, linear flow controlvia a micro-control actuator. Flanged connections ensure reliable sealing, making it ideal for food, pharmaceutical, biotech, and chemical systems requiring stable, high-precision regulation.
Working Principles
The Stainless Steel Positioning Micro-Control Proportional Regulating Flange Diaphragm Valve operates by using a micro-control actuator to convert electrical or pneumatic signals into precise mechanical movement. This movement adjusts the diaphragm, which opens or closes the flow passage proportionally to the input signal, allowing accurate flow regulation. A built-in feedback system continuously monitors the diaphragm position, correcting deviations to maintain the desired opening. The diaphragm design ensures a tight seal and prevents leakage, while the proportional control provides smooth, linear, and stable flow adjustment. This mechanism makes the valve ideal for high-precision applications in food, pharmaceutical, and sanitary systems.
