ZFV Cast steel ball valve is divided into: floating ball valve and trunnion mounted ball valve. Nylon are usually used as seat sealing ring materials in the production of our company. Therefore, in the selection of the structure and performance of the ball valve, the fire resistance and fire prevention of the ball valve should be considered, especially in the departments of petroleum.
The ball valve with metal seat can be selected for the pipeline system with working temperature above 200 ℃. Metal seat ball valve seal ring is alloy steel overlay welding, so hard seal ball valve will not produce too much wear when opening and closing, generally suitable for high temperature and high pressure conditions.
① with the lowest flow resistance (actually 0)
② it can be reliably applied to corrosive medium and low boiling point liquid because it will not stick during operation (when there is no lubricant)
③ complete sealing can be realized in a large range of pressure and temperature
④ the working medium is sealed reliably in both directions
⑤ the valve body is symmetrical, especially the welded valve body structure, which can well bear the stress from the pipeline
【Regarding To ZFV Packing】
1、ZFV main packing include : plastic bag, foaming sheet, plywood case, fumigated wooden box, etc
2、ZFV general packaging procedure is as follows: For small size valves, wrap the valve with plastic bag and foam board, then put the valve into the box, and use some planks to separate the valves in the box.
3、For larger sized valves, we will choose independent packaging.
4、All valves in the box should be securely fastened. In this way, the valve and the box will not collide with each other during transportation, thus avoiding damage to the valve during transportation.
5、We can also package products according to customer's special requirements.
