Present a more advanced triple eccentric butterfly valve is metal seal butterfly valve fittings, valve and seat components for the piece, seat sealing surface layer welding temperature, corrosion resistant alloy material. Multilayer soft stacked ring fixed in the valve plate, this butterfly valve in comparison with the traditional high temperature valves, easy operation, open and close without friction, closed with the transmission of the torque increases to compensate for seal, to improve the sealing performance and prolong the life of the butterfly's advantage. 1, butterfly main control parameters for size specifications. 2, a single butterfly valve plate valve price, its simple structure, easy processing, low cost, easy to operate, but the regulation accuracy is poor, only for ventilation and air conditioning systems for switch or coarse adjustment occasions. 3, can be manual, electric or zip-operation, fixed at any angle 90 ° range. 4, due to the uniaxial single valve plate, endurance limited valves, fittings, in the great pressure, high flow conditions the valve short life. The valve has closed and the general style of the points, thermal and non-thermal points. 5, electric butterfly just double-control, electric valve actuators and multi-leaf same. Valve Factory, valves, valve provided by the Hong Kong Ming Ming Port Valve Co., Ltd., Dongguan. Port Valve Co., Ltd., Dongguan Ming (www.gdmgfm.com) strong, credible, butterfly and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers.
