Butterfly valves

14b - High performance lugged style butterfly valve


The Pfeiffer BR14b double eccentric control butterfly valve is designed for general service applications up to the limits of the PN16 pressure class rating. These general service applications include process events such as erosion, abrasion, and corrosion. The Pfeiffer BR14b design increases flow capacity but also reduces the pressure recovery factor, making the design more susceptible to cavitation, flashing, and flow noise generation. The double eccentric design of this butterfly valve will reduce the breakaway torques required from the actuator.

The Pfeiffer BR14b control butterfly valve has standard options such as low and high temperature versions. The Pfeiffer BR14a and BR14b 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.
