GDF-4 Motor Pipeline Stop Valve bakeng sa Metara ea Phallo ea Khase
Tlhaloso ea Sehlahisoa
GDF-4 pipeline stop valve ke valve e nang le ts'episo e phahameng, bophelo bo bolelele ba ts'ebeletso le koloi ea micro-motor. Tekanyetso e ka sehloohong ea ts'ebetsong ea moralo ke GB/T 20173-2013 "Li-Valves tsa Phaello ea Pipeline ea Phaello ea Lipeipi tsa Indasteri ea Oli le Khase ea Tlhaho", 'me maemo a moralo oa flange ke GB/T 9113-2010 "Integral Steel Pipe Flange".
