Information

1, the selection of materials, in line with the relevant standards at home and abroad, the overall quality of the material is high.


2, meet the requirements of advanced standards at home and abroad, reliable sealing, good performance, beautiful shape.


3, the sealing pair pair is advanced and reasonable, the sealing surface of gate and seat is made of Stellite cobalt base hard alloy with different hardness, reliable sealing, high hardness, wear resistance, high temperature resistance, corrosion resistance, good abrasion resistance and long life.


4, the valve stem after quenching and tempering and surface nitriding treatment, has good corrosion resistance, abrasion resistance and abrasion resistance.


5, wedge type elastic ram structure, large diameter set thrust bearing, friction is small, and equipped with manual impact, open and close easily.


advantages


1, fluid resistance is small, sealing surface by medium brush and erosion is small.


2, open and close less effort.


3, the flow direction of the medium is not restricted, no turbulence, no pressure reduction.


4, simple body, short structure length, good manufacturing technology, wide range of application.


disadvantages


1, between the sealing surface is easy to cause erosion and abrasion, maintenance is more difficult.


2, the external size is large, the opening needs a certain space, opening and closing time is long.


3. The structure is complex.
