TOZEN Butterfly Valves

Compared with other traditional isolating valves such as Gate Valves, Globe Valves and Ball Valves, Tozen Butterfly Valves offer the following advantages: 
• They are suited for both isolation and control purposes. 
• The light weighted and compact design reduces installation, storage and transport costs. 
• They can be installed at any selected position. 
• The centrally mounted disc and hydrodynamic design minimize pressure loss. 
• Excellent flow characteristics with flow in either direction optimally achieved in the operating range between 15° and 70° opening. 
• No gasket is needed for installation. 
• Gas tight sealing in either direction.
TOZEN butterfly Valve Size range : 50mm to 350mm (2" to 14") 
Working pressure : 16 bar 
Working temperature : 0°C to 90°C (EPDM seat)  0°C to 70°C (NBR seat)
To ensure tight shut off for application in chemical processing plants, power plants, refineries, shipbuilding, pulp and paper mills and HVAC applications, Tozen butterfly valves are specially designed to strengthen the seal tolerance between the disc and the liner.
Tozen butterfly valves are highly competitive with their absolutely tight sealing, corrosion resistance and low operation torque requirement. Thus, minimal operational wear and an extended service life are the long-term benefits committed to the users.
