KDV Straight Through Type DIAPHRAGM VALVE
Glass Lined Straight Through Diaphragm Valve
KDV’s Glass Lined Straight Through Diaphragm Valve is designed for reliable flow control in applications involving slurries, acidic sludge and other demanding process media. Its straight-through flow path and borosilicate glass-lined body provide a durable solution for compatible industrial applications while isolating line media from the valve’s mechanical components.
