Description
Tantalum Butterfly Valve
WDL Tantalum Butterfly Valve provides compact quarter-turn isolation or flow regulation for process systems that need acid resistance in selected highly corrosive chemical processes. Tantalum-wetted construction is considered for severe acid service when corrosion allowance is not an acceptable solution.
