Wedge gate valve has following advantages
1 Small flow resistance, sealing face suffers less flush and corrosion.
2 Low torque operation, easy operation
3 Direction of medium is not limited, not generate disturbed flow, and not reduce medium pressure.
4 Simple structure, short face-to-face dimension, process precisely and widely applicable
5 Product fabrication is strictly according to API 600, full port design, on full open position, valve disc is higher that flow direction to guarantee flow smoothly, reduce pressure loss, high transmission efficiency.
6 For carbon material valve, seat is forged, high density, good sealing capacity. Sealing face use 13Cr or Stellite hard alloy material, overlay net thickness is over 2mm, valve seat is threaded or welded on the valve body, easy to maintain and dissemble.
7 Adopt rising stem, stem and disc is connected by a T shaped groove, T head and stem is forged together to guarantee enough connection strength. Flexible disc structure can avoid stuck caused by heat inflation
8 Back seal design will protect packing when valve is fully opened. Packing is flexible graphite, good sealing capacity, and also venting system is available. Packing bush and gland are ball structure, pressure process will enable the stem to automatically centralized, avoid stem stuck.
9 Bolted bonnet structure and thick hex nut fastening parts will ensure reliable function. Gasket adopt flexible graphite twist stainless steel or octagonal ring to get good sealing effect
10 Top entry nut design assures that, when the valve is open, even if demount the hand-wheel, stem and disc will not fall down. Stem is made by Aluminum bronze, and both sides set bearing, all this made the valve easy to operate.
