Main characteristics as follows:

Small and light, easy disassembling and maintenance, and can be installed in any position;Simple and compact structure, small operation torque, 90 ° rotating open quickly;Flow curve tending to straight line regulation performance good;

Be used between the butterfly plate and the valve stem structure without pin, overcome the possible leak inside;Butterfly plate adopts the cylindrical spherical shape and improve the sealing performance and prolong the service life of the valve, with pressure opening and closing more than 50000 times remains zero leakage.The seals can be replaced, and reliable sealing achieve two-way sealed;

Butterfly plate can spray coating according to user requirements, such as nylon or ptfe classes;The valve can be designed as flange connection and the connection to the clamp;Can choose manual, electric or pneumatic drive mode;Novel design, reasonable, unique structure, light weight, rapid opening and closing;Small operation torque, easy to operate, saving smart;Can any position installation, convenient maintenance;The seals can be replaced, sealing reliable performance to achieve two-way sealing zero leakage;Sealing material ageing resistance, corrosion resistance, long service life, etc.
