Straight Through Diaphragm Valve

ALIS Valves offers Straight Through Diaphragm Valves for industrial applications requiring reliable flow regulation, tight shut-off and efficient handling of fluids containing suspended solids. These valves feature a straight-through flow passage that allows media to move through the valve with minimal changes in direction, helping reduce flow resistance and the risk of material accumulation. A flexible diaphragm moves against the valve’s sealing area to regulate or stop the flow while isolating the operating mechanism from direct contact with the process media. Depending on the valve design, the body and diaphragm materials can be selected to suit different chemical and operating conditions.

Straight Through Diaphragm Valves are suitable for applications in chemical processing plants, mining operations, wastewater treatment facilities, pulp and paper industries and other industrial fluid handling systems. They can be used for compatible liquids, slurries and fluids containing suspended solids, depending on the diaphragm material and valve construction. Important selection factors include process media, solids concentration, operating pressure, temperature, flow rate, valve size, body material, diaphragm compatibility and end connection type. Selecting the appropriate Straight Through Diaphragm Valve helps support effective flow control, dependable shut-off and reliable performance under the intended operating conditions.
