Application

Get control with the Bradford™ B5104 sanitary butterfly valve. The slim design, superior craftsmanship, 316L materials, top quality strength and surface finish make the B5104 the preference of many wineries, breweries and a multitude of other industries with sanitary requirements. Various elastomers, end types and accessories make this a highly versatile valve.

Working Principle


The B5104 is actuated manually with a handle, or controlled remotely by an actuator. The actuator is available in pneumatic or electric designs. Manual actuation of the valve is achieved with a 4-position push handle. The quarter turn handle is equipped with 4 stop devices at the open, closed and intermediate positions of 30° and 60°. The push handle is available as standard counter clockwise (CCW) to open or with a clockwise (CW) hub to open.
Pneumatic actuators are available in three styles:
  • air to open - spring to close (ATO/STC)
  • air to close - spring to open (ATC/STO)
  • double acting (ATO/ATC)
The vertical cylindrical design of the actuator translates axial travel of the piston into a 90° rotary movement of the shaft. Rack and pinion design is also available.
