High pressure gate valve (bevel gear) is suitable for cutting off or connecting medium on pipelines of petroleum, chemical and thermal power plants with working pressure of 900-2500 LB and working temperature of - 29-570 ℃. Applicable media: water, oil, steam and other non corrosive media.
1. The valve and pipeline are connected with flanged structure.
2, fluid resistance is small, sealing surface by medium thin brush and erosion.
3. The sealing surface of valve disc and valve seat is made of SLITE, which has good abrasion resistance, high temperature resistance, good abrasion resistance and long service life.
4, the flow direction of the medium is not restricted, no disturbance, no pressure reduction.
5, the valve cover stuffing box reasonable, packing with corrosion inhibitor, sealing reliable, smooth switch.
6. Simple shape, short structure length, good manufacturing process, wide application range.
