High reliability

No Screw between Disc and Shaft
The disc and shaft connection features all of the benefits of a high strength 2 piece design with the disadvantage associate with designs using taper pins or disc screw which often fail through abrasion, corrosion of fatigue. The disc edge is spherically machined and hand polished to produce a bubble-tight shut off minimum torque and longer seat life.

No Gasket required
O-rings or gaskets are not required when installation.

Low Torque
Valve discs are sperical machined and polished. Every parts of sealing surface is spherical. These fit together with a smooth and low torque when close and open. The raised center seat has the cosine-curve structure.

Perfect Sealing
seat and disc is sealed as flat surface matched both top and bottom shaft point. This unique sealing gives perfect tight at low torque and smooth touch.

Top Flange
It is in accordance with ISO5211 and it matches with any type of actuators.

Testing
Butterfly valves are confirmed to API 598 and BS5155. Body pressure test to be done 150% and shell to be 110% of maximum working pressure.
