Bio-Tek Valve

The Bio-Tek^® diaphragm valve is a compact, lightweight solution for reducing contamination in process systems. Available sizes are 1/4", 3/8" and 1/2" (DN 6, 10 and 15). The Bio-Tek valve features a body design that allows the inlet and outlet ports to be customized to the desired tube size. This design feature allows the same size bonnet, diaphragm and actuator to be interchangeable among all Bio-Tek valves sizes, facilitating maintenance and reducing the number of replacement parts.
