26000 Valve
D103337X012
Baumannt 26000 Corrosion Resistant
Control Valve
The Baumann 26000 is a unique corrosion resistant
control valve featuring a flangeless wafer valve body
and powerful multi-spring diaphragm actuator. This
valve is available with a Fisherr FIELDVUEt digital
valve controller to allow for highly accurate, low flow
control of nearly all corrosive media. (Note: For
optimal, non-compromisedvalvelife,fluidmustbe
clear and service non-cavitating.) A solid corrosion
resistant R05200 Tantalum or N10276 Nickel Alloy
valve plug and pressure-assisted PTFE seat combine for
an extremely wide control range making the 26000
series ideal for pH control applications.
An S31600/S31603 stainless steel flangeless valve
body, thru-hole wafer design, allows for installation
between plastic pipe line flanges without risk of gasket
leakage. Top entry trim provides ease of servicing and
alongoperatinglife.
