MANUAL “2 WAY” DIAPHRAGM VALVE FLANGED END
“aline” Make Manual Diaphragm Valve – Flanged End is specially designed for reliable shut-off and flow control of corrosive, abrasive, viscous, and contaminated fluids. The valve operates using a flexible diaphragm that completely isolates the operating mechanism from the process media, ensuring leak-proof performance, contamination-free operation, and extended service life.
Its flanged end design provides secure installation and excellent sealing in industrial piping systems. The non-rising handwheel mechanism allows smooth manual operation with minimal effort, while the diaphragm provides bubble-tight shut-off without requiring conventional stem packing. This makes the valve an ideal choice for applications where hygiene, corrosion resistance, and leak prevention are critical.
Manufactured using high-quality materials and precision engineering, ALINE Manual Diaphragm Valves are widely used in Chemical Processing, Pharmaceutical Industries, Water Treatment Plants, Food & Beverage, Pulp & Paper, Mining, Fertilizer, Power Plants, Textile Industries, and General Process Applications.
Designed for long-lasting performance and minimal maintenance, the ALINE Manual Diaphragm Valve delivers reliable operation even in demanding industrial environments.
