51b - Ball valve for safety shut-off application - block & bleed

51b

The Pfeiffer BR51b tight-closing, shut-off ball valve made of non-corrosive materials is designed for aggressive media, especially as an exchangeable unit for block & bleed shut-off devices in chemical plants. The BR51b safety shut-off ball valve combines the functions of a shut-off valve and a block & bleed valve in a single configuration.

The Pfeiffer BR51b can be assembled with a pneumatic, electric, or hydraulic actuator also offered by the SAMSON Group to complete the construction of the control valve. These 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.
