Features
This is the basic type of diaphragm valves with weir in the flow path. Close contact between the diaphragm and the weir maintains airtightness and provides high valve seat sealing performance.
Many material options for main bodies and diaphragms, including rubber and fluorocarbon resin, enable choosing the most suitable selection based on fluid composition, especially when high cost performance, corrosion resistance, and chemical resistance are necessary.
You can also select actuators based on the application.
