Features

1) Integral rubber-coated gate: The ductile iron skeleton is covered with high-performance rubber and the latest vulcanization technology inside and outside. 2) One-piece copper nut: The copper nut of the valve stem and the ductile iron bracket are tightly connected together by a special process to ensure that they will not be loosened under long-term operation and avoid the control failure of the valve. 3), low-level valve seat: the bottom of the elastic seat seal gate valve adopts a full-flow straight-through design, which is equivalent to a straight pipeline, and it is not easy to accumulate debris, ensuring reliable sealing and unobstructed fluid flow. 4) Lightweight structure: The compact structure reduces the maximum working height by more than 60mm to 300mm compared with the traditional gate valve, saving engineering space; the body is made of ductile iron material, and the weight is reduced by about 20% to 30% compared with the traditional gate valve, and the installation and maintenance are convenient. 5) Corrosion resistance: The inner and outer surfaces of the valve are painted with epoxy resin powder, and the inner parts are made of stainless steel and copper alloy to prevent rust and fluid corrosion. 6) Four seals are used to completely prevent the leakage of the valve: the first seal, the upper seal of the valve stem and the valve cover, is sealed with high-quality O-rings; the second seal, between the valve cover and the valve body Special sealing ring is used; high-quality O-ring is used between the third valve stem and the stuffing box; high-quality O-ring is used between the fourth valve stem and the packing gland bracket. 7) The valve stem is made of high-quality stainless steel, and the hardness of the valve stem reaches HB200-275 after quenching and tempering treatment, which not only ensures the strength of the valve stem, but also increases the wear resistance of the valve stem. 8) The open rod structure can judge whether the valve is open or closed through the opening height of the valve rod, and there is no need to add a position display device. 9) The connection method adopts groove type, which is quick and convenient to install.
