1. One-piece copper nut valve core copper nut and ductile iron skeleton, the use of special technology tightly connected to ensure that the long-term operation and the impact of the current will not loose, to avoid valve control failure.
2. Flat-type valve seat The company's elastic seat sealing valve bottom of the full basin through-type design, equivalent to the pipeline, not easy to accumulate debris, to ensure reliable sealing, so that the flow unimpeded.
3. Since sealing bonnet bonnet and valve body adopt self SEAL structure design, in allowable pressure range, the higher the fluid pressure, the more tightly sealed.
4. The structure is lightweight and compact, the maximum working height is lower than the traditional gate valve 60mm-300mm above, save the engineering space, the body uses ductile iron material, the weight is less than the traditional gate valve reduces about 20%-30%, installs the maintenance to be convenient.
