The Pfeiffer Type BR 21a PTFE-lined drain ball valve is designed for tight-closing applications for corrosive media, especially for high process demand in chemical plants.

The controlling device consists of a PTFE-lined drain ball valve with a pneumatic quarter-turn actuator, a manual gear, or a lever.

They can be assembled with a pneumatic, electric, or hydraulic actuator also offered by the SAMSON Group to complete the construction of the control valve. These control valves are designed according to the modular assembly principle.
