• Material Properties: Stainless steel gate valves are typically made from grades such as 304 or 316, known for their excellent corrosion resistance and mechanical strength. These materials can withstand harsh environments, including exposure to chemicals and corrosive substances.
• Design Features: Stainless steel gate valves often feature a wedge-shaped gate that compresses against the seat to create a tight seal. The design ensures minimal leakage and reliable shutoff.
• Performance: Stainless steel valves offer high resistance to corrosion and oxidation, making them suitable for applications involving corrosive fluids. They also maintain their performance in high-temperature environments.
• Chemical Processing: Stainless steel gate valves are ideal for chemical processing plants where resistance to corrosive chemicals is crucial.
• Food and Beverage: These valves are used in food and beverage industries due to their ability to maintain hygiene and resist corrosion from acidic substances.
• Pharmaceuticals: Stainless steel valves are preferred in pharmaceutical applications for their durability and resistance to sterilization processes.
• Material Properties: Cast steel gate valves are made from materials such as carbon steel or alloy steel. These materials provide high strength and durability, making them suitable for high-pressure and high-temperature applications.
• Design Features: Cast steel gate valves often feature a robust design with a sliding gate that moves vertically to control fluid flow. The design ensures reliable shutoff and minimal wear over time.
• Performance: Cast steel valves are known for their ability to handle high pressures and temperatures. They are less susceptible to deformation under load, ensuring long-term reliability.
• Oil and Gas: Cast steel gate valves are commonly used in oil and gas pipelines due to their ability to withstand high pressures and temperatures.
• Power Generation: These valves are used in power plants for their durability and reliability in high-temperature environments.
• Heavy Industry: Cast steel valves are preferred in heavy industrial applications where strength and durability are critical.
