Product Description

Work Principle:
In its typical state, the valve remains securely closed as the elbow diaphragm effectively seals the valve's inner cavity, efficiently blocking the pipeline path.
By effortlessly toggling the handwheel or actuating the drive, the valve stem is propelled upward, bending the spherical diaphragm to create an upward motion. This transformative action shifts the valve into a conductive state, enabling seamless cleaning and opening functions. Ingeniously designed, the diaphragm acts as a barrier, isolating the lower valve body's inner cavity from the upper valve cover. This protects crucial components like the valve stem and core from harmful corrosion. Our advanced design eliminates the need for pack-sealing structures, ensuring zero medium leakage. Furthermore, the refined valve body design prevents any cleaning fluid stagnation, allowing for complete and efficient drainage.
Scope of Application:
Our diaphragm valves are exceptional performers in industries such as wine, dairy products, beverages, foodstuff, and pharmaceuticals. They are designed to meet the stringent control and open/close requirements for sophisticated pipeline systems.
