The rubber elastomer butterfly in continuous use, will produce tear, abrasion, aging, wear polymer composites repair valve hole even wear off phenomenon. The conventional thermal curing process is difficult to adapt to the needs of the repair site, to be used when repairing specialized equipment, consume large amounts of heat and electricity valves, time-consuming and laborious. Today the gradual use of polymer composites alternative to traditional methods Tanggu first valve plant, which is the most widely blessing World Blue technology system. Its products have excellent adhesion and excellent abrasion resistance, tear resistance, to ensure that after the repair to meet or exceed the life cycle of a new part of Tanggu Valve Plant, greatly reducing downtime. Butterfly valve when fully opened, with a smaller flow resistance. When turned on between about 15 ° ~ 70 ° Tanggu Watts Valve Factory, but also for sensitive flow control, thus regulating the field of large diameter, butterfly application is very common. Since the motion of the butterfly valve disc with a rubbing resistance, so most of the butterfly valve can be used for media with suspended solid particles. Based on the strength of the seal, may also be used for powder and granular media. Tanggu valves, valve, the valve is 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. The company better work attitude and constantly improving innovative ideas will lead the next port of the valve and you hand into the brilliant, for a better future!
