Stainless Steel Gate Valve
A gate valve structure having a slab gate and a pair of opposed seat assemblies on opposite faces of the slab gate. A generally U-shaped spacer member of substantially the same thickness as the slab gate is loosely positioned between the opposed seat assemblies outwardly of the slab gate to maintain a predetermined minimum spacing between the seat assemblies. The U-shaped spacer member has a smaller thickness portion thereof in its center section to provide flexibility for permitting alignment of the spacer member upon canting or cocking of the seat assemblies.
Material: WCB, WCC, LCB, LCC, WC6, WC9, CF8, CF8M, CF3, CF3M, CF8C, etc
Operation: Hand Wheel, Electricty, etc
1. In order to prevent abnormal pressure in the cavity, relief holes are equipped on inlet side.
2. The bonnet top length are determined according to the operating temperature of the valve, to ensure reliable packing sealing.
3. Packing, gasket and other parts material are decided according to the working temperature.
4. Strictly control the chemical composition of materials and low temperature impact toughness and other mechanical properties.
