Top loading brake metal butterfly valve Product Overview
Top loading metal seal butterfly valve is a multi-level three eccentric metal seal butterfly valve on the basis of the development of another new product. In addition to having all the superior features of a multi-layered, triple-eccentric metal, hermetically sealed butterfly valve , it is also bi-directional and can withstand pressure. One of the greatest advantages of this valve is that it can be repaired in the field. With the choice of valve material, the use of temperature from -29 ℃ ~ 550 ℃, due to its good flow can both turn off the media, you can also adjust the media flow.

Loading brake metal seal butterfly valve Features:
Top loading brake metal butterfly valve mainly by the valve body, valve cover, disc, valve shaft, valve seals, disc seals, bushings, bottom cover, drive and other components, has the following characteristics:
Top loaded gate structure to solve the traditional eccentric butterfly valve can not be repaired in the field. In accordance with the original multi-level three eccentric butterfly valve , when the ring is damaged, you need to return to the manufacturer to repair or remember a butterfly valve scrapped. The upshift butterfly valve need not be removed from the pipeline and can be taken out of the body cavity together with the stem and disc for repair or replacement of the sealing ring in just a few minutes and then capped Mouth, you can achieve during the maintenance of the valve can not affect the normal operation of the pipeline system, so that maintenance of the valve caused by the loss of benefits to a minimum;
Multi-level three eccentric metal seal butterfly valve all the good performance;
Reliable sealing function, up to the gas seal no leakage;
Butterfly streamlined design, with high strength, large flow area, small flow resistance, energy saving;
