Stainless Steel Gate Valve

What is a Stainless Steel Gate Valve?

ZECO stainless steel gate valve is used for pipelines with corrosive media. For any kind of stainless steel material, the ability to resist medium corrosion is relatively limited and is affected by many external factors, such as temperature, pressure, and PH. However, as long as the heat treatment and processing process are completely in accordabyard with the manufacturing process, the material can be guaranteed to withstand corrosion within the range of corrosion. So in the selection of stainless steel gate valves, we need to consider the concentration of the medium, working environment temperature, and the selection of materials and other factors on corrosion resistance. 

ZECO Valve is a stainless steel gate valve manufacturer for nearly 30 years, providing professional suggestions for users to choose models and materials for working conditions.

How does a Stainless Steel Gate Valve work?

A stainless steel gate valve operates similarly to other valves. To open the valve, turn the handwheel, which moves the gate up or down on the stem via the threads. A stainless steel gate valve requires more than one 360° turn to open or close the valve fully. When the stainless steel gate is lifted, it opens the inlet to the outlet allowing an unobstructed passageway for the media to flow. When the stainless steel gate is lowered, it closes and blocks the media flow.

Applications of Stainless Steel Gate Valves

Because of its resilience, a stainless steel gate valve is used in an array of industrial applications. These include:

  • Oil and gas industry;
  • Chemical and pharmaceuticals;
  • Marine;
  • Water and wastewater treatment;
  • Manufacturing industries.
