Truss design 
Disc design truss, truss structure is mainly axial tension or pressure, which can make full use of the material strength, the larger span than the solid body to save material, to reduce weight and increase the rigidity while reducing fluid resistance, suitable for large diameter butterfly valve;
Replaceable seals 
Seals can be replaced by forms, T-type structure made of high quality rubber seals, rubber to ensure flexibility and aging resistance, uniform pressure plate clamping ring structure in the case of partial still being worn down ratio abandon for some flexibility in compensation;
Composite bushings 
, The lower stem and the body made of composite material are set bushings, bushings having high strength and high-quality finish, with self-lubricating ability, reducing the force generated by the rotating friction reducing valve operating torque;
Combination sealing ring 
And valve stem seal is a dynamic seal leaks at the valve stem butterfly has always been a problem more often now bow shaped frame inlaid with PTFE rubber O-ring structure, while ensuring a reliable seal but also has some lubrication, reducing stem and the body of the rubber O-ring wear and improve the pot life;
Pulling back off of fixed 
Stem and disc using tapered pin connection, reducing the stem and disc with the gap and improve the stability of the disc running while pulling back off using special tools dismantled to make interchangeability of parts increased, indirectly improve valve for life;
Adjustable angle 
Disc sealing surface between the valve seat and stainless steel can have ± 1 ° adjustment amount, in the case of the sealing surface wear elastic compensation has some margin.
Various implementing agencies 
Butterfly has a standard connection bracket for easy selection of a variety of actuators, such as: worm gear structure, pneumatic actuators, electric actuators, electro hydraulic actuators and so on.
