Ball valves

26a - Two-piece floating ball valve


The Pfeiffer BR26a stainless steel tight-closing ball valves are designed for general service applications up to the limits of the PN40 pressure class rating. These general service applications include process events such as erosion, abrasion, and corrosion. The Pfeiffer BR26a design increases flow capacity but also reduces the pressure recovery factor, making the design more susceptible to cavitation, flashing, and flow noise generation.

The Pfeiffer BR26a can be assembled with a pneumatic, electric, hydraulic, or electro-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.
