Diaphragm Valve Zubi T100 Weir Type
The Zubi T100 is a flanged diaphragm valve of the weir type, bidirectional, featuring a one-piece cast body and bolted bonnet. The weir design reduces diaphragm travel and allows for on/off operation with limited throttling capability, depending on media and diaphragm wear. Available in lined and unlined versions for corrosive or abrasive industrial fluids, with usage reference up to 15% solids.

Applications
The T100 is used in water and wastewater, chemical auxiliary circuits, pulp & paper, power generation, mining, powder/bulk handling, and food/beverage with appropriate material confirmation. Selection is based on pH, temperature, solids content, operation frequency, and cleaning requirements.
Handling and Automation
Available with handwheel, pneumatic actuator air-open, air-close, or double acting, electric actuator, and gearbox. Options: position indicators, switches, solenoid valves, padlocks, mechanical limit switches, and positioner 4–20 mA.
Difference from Zubi T85
The T100 is a weir type chosen for compact diaphragm isolation with a lined body. The T85 is straight-through/full bore, preferred for higher solids passage or when material retention must be minimized.
