PTFE/PFA Lined Rotary

10e - PTFE-Lined Centric Butterfly Valve

Size: 2" to 16"

ANSI Class: 150

Std. Materials: PTFE Lined Cast Iron

Temperature Range: -58 to 392oF (-50 to 200oC)

The Pfeiffer BR10e PTFE lined centric control butterfly valve is designed for general service applications up to the limits of the ANSI 150 pressure class rating. These general service applications focus on extremely corrosive media found in chemical processes. The Pfeiffer BR10e design increases flow capacities 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, hydraulic, or electro-hydraulic actuator also offered by the SAMSON group to complete the control valve construction. These control valves are designed according to the modular assembly principle, can be equipped with SAMSON GROUP actuators and valve accessories such as positioners, limit switches, and solenoid valves.
