Features

VAHN-TECH Top Entry Ball Valves are used in pipelines and critical process applications. These valves are fully in-linefiled repairable, thus eliminating long down times. The bolted construction allows disassembly on-site for inspection and possible repair. Ball and Seats can be removed and replaced in-line. The valves have standard design features such as a built-in cavity relief mechanism, anti-static, emergency sealant injection, drain and vent.
