Valves are important control components in industrial production, used to control process parameters such as flow, pressure, and temperature. The sealing surface is a key component of a valve, and the choice of material has a significant impact on its performance and lifespan. This article will introduce common valve sealing surface materials and their advantages.
Rubber
Rubber is a commonly used valve sealing surface material, offering excellent corrosion resistance, wear resistance, and elasticity. Rubber sealing surfaces can achieve effective sealing at lower pressures and temperatures. Rubber also has good wear and aging resistance, extending the lifespan of the valve. Advantages: Corrosion resistance, wear resistance, good elasticity, and low price.
Plastic
Plastic is also a common valve sealing surface material, with advantages such as good corrosion resistance, wear resistance, and high temperature resistance. Plastic sealing surfaces are commonly used in industries such as the chemical and food industries, providing excellent sealing results. Advantages: Corrosion resistance, wear resistance, high temperature resistance, and reasonable price. Babbitt Alloy
Babbitt alloy is a valve sealing surface material with excellent corrosion and wear resistance, commonly used in industries such as marine and chemical industries. Advantages: Excellent corrosion, wear, and abrasion resistance.
Copper Alloy
Copper alloy has excellent wear resistance, corrosion resistance, and thermal conductivity, and is commonly used in low-pressure, low-temperature piping systems. Advantages: Wear resistance, corrosion resistance, good thermal conductivity, and reasonable price.
Stainless Steel
Stainless steel is a valve sealing surface material with excellent corrosion and high-temperature resistance, commonly used in industries such as chemical and petroleum industries. Advantages: Corrosion resistance, high-temperature resistance, and abrasion resistance.
In summary, the choice of valve sealing surface material should be based on the specific operating conditions and requirements. Different sealing surface materials have different advantages and characteristics. Choosing the right material can greatly improve valve performance and service life.
