a.Austenitic stainless steel has good corrosion resistance to oxidizing acid medium;
b.Medium flow through the stainless steel gate valves does not change its flow direction, small fluid resistance;
c.The movement direction of the gate is perpendicular to the flow direction of the medium;
d.The flow direction of the medium is unrestricted, free from disturbance and pressure reduction. The medium can flow in any direction from both sides of the gate valve to achieve the purpose of use.
e.The gate is vertically placed in the valve body, with short structure length.
f.Good sealing performance, small erosion on sealing surface when fully opened.
