High pressure stainless steel gate valves
High pressure stainless steel gate valves
Model: | Z41W | Size: | DN25-DN500 |
Pressure: | 6.4MPA-10MPA | Material: | 304/316(R)/304L/316L |
Advantages:
1, The fluid resistance, the strike and erosion of the medium to the sealing is small.
2, the open and closing is easy
3, the flow direction is unlimited. And the pressure will not be reduced.
4, simple body, short length, fine casting, wide application.
