26s - Heavy Duty Trunnion Mounted Ball Valve

Size: 1" to 32" (DN 25 to 800)

Pressure Class: 150 to 300 (PN 10 to 40)

Std. Materials: Carbon Steel, Stainless Steel

Temperature Range: -325 to 1022oF (-196 to 550oC)

The Pfeiffer BR26s is a floating or trunnion mounted high performance ball valve designed for general service applications up to the limits of the ANSI 300 (PN 40) pressure class rating. These general service applications include process events such as erosion, abrasion, and corrosion. The Pfeiffer BR26s design increases flow capacities but also reduces the pressure recovery factor making the design more susceptible to cavitation, flashing, and flow noise generation.

The Pfeiffer BR26s 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.
