14b - HD - Double eccentric butterfly valve of stainless steel or precious metal
The Pfeiffer BR14b HD tight-closing, double-eccentric butterfly valve is designed for the high demands of the the chemical industry up to the limits of the PN16 pressure class rating. The Pfeiffer BR14b HD 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 HD 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.
