Butterfly, ball and rotary plug lined valves

10e - PTFE-lined centric butterfly valve


The Pfeiffer BR10e PTFE-lined centric control butterfly valve is designed for general service applications up to the limits of the PN16 pressure class rating. These general service applications focus on extremely corrosive media found in chemical processes. The Pfeiffer BR10e design increases flow capacity but also reduces the pressure recovery factor, making the design more susceptible to cavitation, flashing, and flow noise generation. The centric design of this butterfly valve will require greater breakaway torques from the actuator.

The Pfeiffer BR10e 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 and can be equipped with SAMSON Group actuators and valve accessories such as positioners, limit switches, and solenoid valves.
