PQ340F/H Eccentric ball valve

PQ340F/H mounted eccentric hemispherical valve is a new product developed successfully in the absorption of advanced technology at home and abroad. It is also an innovative product to fill the blank of domestic valves. It is a complete and innovative product developed from similar products in Germany on the premise of carefully weighing the advantages and disadvantages of ball valves, butterfly valves and gate valves. The conclusion of the appraisal is that the performance of some aspects is better than that of similar products such as gate valves, globe valves and ball valves. The eccentric hemispherical valve is used to weld different alloys according to the needs of the user. The selection of the bimetal sealing ring can be used in different industrial sectors, such as wear resistance, corrosion resistance, high temperature resistance and so on.

Advantages

1., the fluid resistance is small, and its drag coefficient is equal to the pipe length of the same length.

The 2. is simple in structure, small in size and light in weight.

3. reliable and reliable. Currently, the sealing surface materials of ball valves are widely used in plastics and are well sealed. They are also widely used in vacuum systems.

4. easy operation, quick opening and closing, and full turn to full clearance as long as 90 degrees of rotation to facilitate remote control.

5. maintenance is convenient, the ball valve structure is simple, the seal ring is generally active, dismantling and replacement are more convenient.

6. when fully open or fully closed, the sealing surface of the ball and valve seat is separated from the medium. When the medium is passed, the sealing surface of the valve will not be eroded.

7. it has wide application range, small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure.
