Tozen Butterfly Valve

Tozen BFV (wafer type), BFV-L (full lugged type), and BFV-D (flanged type) are soft sealing butterfly valves for installation with flanges drilled in accordance with JIS, ANSI, BS, DIN, etc. Overall lengths are in accordance with ISO 5752 series 20. Actuator mounting flanges conform to ISO 5211.

To ensure tight shutoff for application in chemical processing plants, power plant, refineries, shipbuilding, pulp and paper mills, and HVAC applications. Tozen butterfly valves are specially designed to strengthen the seal tolerance between disc and liner.

High quality control are focused on precision machining of valve bodies and disc, and on positioning of rubber liner within the body and exact positioning of shaft. Promary seal is achieved at the interface of the disc and the surface of the liner, particularly in the area of the shaft locations. Pressure surge seals are molded inside the seat shaft collars providing supplementary security. These multiple seals ensure that the medium comes into contact only with the disc and the urbber seat.

Tozen butterfly valves are highly competitive with their absolutely tight sealing, corrosion resistance and low operational torque requirement. Thus, minimal operational wear and an extended service life are the long-term benefits committed to users.
