PTFE/PFA Lined Rotary

20b - PFA-Lined Ball Valve

Size: 1" to 8" (DN 25 to 200)

Pressure Class: ANSI 150 (PN 16)

Std. Materials: PFA Lined Cast Iron

Temperature Range: 14 to 392oF (-10 to 200oC)

The Pfeiffer BR20a PFA lined ball valve is designed for general service applications up to the limits of the ANSI 150 (PN 16) pressure class rating. These general service applications focus on extremely corrosive media found in chemical processes. The Pfeiffer BR20b design increases flow capacities but also reduces the pressure recovery factor making the design more susceptible to cavitation, flashing, and flow noise generation. The design of this floating ball valve will have increased breakaway torques required from the actuator.

The Pfeiffer BR20b 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.
