Researching and comparing different suppliers will help you identify the most reliable ones.
2. What types of valve seals are commonly produced in China?
China produces a variety of valve seals, including soft seals made of materials like EPDM and NBR, which are often used in water treatment and HVAC systems. Metal seals, particularly those made of Inconel or stainless steel, are used in high-pressure and high-temperature environments such as oil and gas pipelines. PTFE-sealed valves are also produced for chemical processing applications.
3. How do Chinese valve seal factories ensure quality control?
Chinese valve seal factories ensure quality control by adhering to strict manufacturing processes that include casting, forging, machining, and assembly. They also conduct thorough testing to ensure the valves operate properly under required pressure conditions. Visual inspections are performed to detect any visible defects or irregularities in construction.
4. What are the common causes of valve sealing failure and leakage?
Common causes of valve sealing failure and leakage include poor seal flushing, unevenly ground sealing surfaces, and improper closure. High or low pressure at the pump inlet can also lead to sealing failure. Regular inspections and preventive maintenance are essential to identify and address these issues early.
5. How can I ensure the durability and lifespan of valve seals sourced from China?
To ensure the durability and lifespan of valve seals sourced from China, you should invest in top-quality valve seal solutions that are free of defaults.
