【Product Use】
Stainless Steel Gate Valve: The valve body, valve cover, gate, and gate stem are made of stainless steel; the valve seat sealing surface is made of polytetrafluoroethylene, stainless steel + hard alloy, or hard alloy overlay welding; the packing is generally made of hard alloy, polytetrafluoroethylene, asbestos graphite, or flexible graphite. Nominal size: DN15~DN800, working pressure: 1.6MPa~20.0MPa, applicable temperature: ≤200℃, suitable for pipelines with nitric acid and weakly corrosive media.
【Product Features】
1. Made of austenitic stainless steel, it has good corrosion resistance to oxidizing acid media.
2. When the medium flows through the stainless steel gate valve, its flow direction remains unchanged, resulting in low fluid resistance.
3. The movement direction of the gate is perpendicular to the flow direction of the medium, requiring small opening and closing torque and less effort for operation.
4. The flow direction of the medium is not restricted, there is no flow disturbance or pressure reduction, and the medium can flow through from either side of the gate valve to achieve the intended use. It is suitable for pipelines where the flow direction of the medium may change.
5. The gate is vertically installed in the valve body, resulting in a short structural length.
6. Good sealing performance. The sealing surface is less eroded when fully open.
