Frequently Asked Questions

Q: What materials are available for custom water valve cores?
We offer brass, stainless steel (304/316), high-purity alumina ceramic, and engineering plastics like POM/PTFE. We select the material based on your specific pressure, temperature, and hygiene requirements.
Q: What size ranges can be customized for the valve core diameter?
We support customization for diameters ranging from Φ5mm to Φ50mm, with various interface types such as threaded, clamped, or welded connections.
Q: How do you ensure the valve core fits my existing equipment?
Our engineering team performs reverse modeling from your provided samples to ensure 100% compatibility with your current valve body and assembly process.
Q: What is the typical lifespan of your ceramic valve cores?
Our ceramic valve cores are tested to exceed 500,000 opening and closing cycles, offering superior wear resistance and a much longer lifespan than traditional materials.
Q: Are these valve cores suitable for drinking water systems?
Yes, we provide 316 stainless steel and food-grade silicone/EPDM seals that comply with international hygiene standards for drinking water and food-grade applications.
Q: Can you customize the opening and closing angles?
Absolutely. While 90° and 180° are standard, we can engineer custom opening angles and specific flow curves to meet your system's operational needs.
