Product Description

⚙️ Product Overview

As the "heart" component of a water valve system, the performance of the valve core directly determines the valve's sealing performance, durability, and operational precision. We have deep expertise in the field of customized hardware components, focusing on the research and development and production of water valve cores. With "precise fit, superior quality, and customization to your needs" as our core principles, we provide cost-effective valve core solutions for customers in various industries, including sanitary ware, HVAC, water conservancy projects, and home appliances, helping to enhance the competitiveness of their end products.

🛠️ Product Features
🏠 Multi-Scenario Adaptability Design Customized valve core flow curves, opening and closing torques, and sealing structures for different scenarios such as household bathroom valves (toilet, shower, basin valves), industrial pipeline valves, commercial water purification valves, and wall-hung boiler valves.
🧪 Flexible Material Selection Offers a variety of material combinations including brass, stainless steel (304/316), ceramic, and engineering plastics (POM/PTFE). 316 stainless steel is preferred for hygiene, while ceramic plates offer 3x more wear resistance.
🎯 Precision Parameter Customization Supports adjustments to diameter (Φ5–Φ50mm), interface types (thread/clamp/welded), and opening angles (90°/180°/custom). Our engineering team ensures perfect compatibility with existing valve bodies.
Quality Assurance

The reliability of the valve core stems from stringent production control and performance testing. We have established a full-chain quality inspection system from raw materials to processing.

1
Strict Selection of Raw Materials: All metal materials are tested by spectroscopy. Ceramic sheets are made of high-purity alumina (sintered at 1700℃), and seals use food-grade silicone or EPDM rubber (-20℃ to 120℃).
2
Precision Machining: Using CNC lathes and five-axis machining centers, accuracy is controlled within ±0.005mm, ensuring smooth operation without jamming.
3
Full Performance Testing: Each batch must pass 12 core tests: sealing test (10 bar pressure), life test (500,000+ cycles), corrosion test (48h salt spray), and temperature shock tests.

Frequently Asked Questions
What materials are available for custom water valve cores?
We offer brass, stainless steel (304/316), high-purity alumina ceramic, and engineering plastics (POM/PTFE). Materials are selected based on your application needs, such as 316 stainless steel for food-grade requirements.
What size range of valve cores can you customize?
We support customization from Φ5mm to Φ50mm in diameter, with various interface types like thread, clamp, and welded connections, and custom opening angles.
How do you ensure the quality and durability?
Every batch undergoes 12 performance tests, including 10 bar sealing tests, 500,000+ cycle life tests, and 48-hour salt spray tests. Machining precision is kept within ±0.005mm.
Can your valve cores fit our existing valve bodies?
Yes. We use reverse modeling from your samples to ensure the customized valve core is perfectly compatible with your existing equipment without modifying your assembly process.
Which industries do your valve cores serve?
Our products serve bathroom building materials, HVAC systems, water conservancy, household appliances, and industrial hydraulic or chemical equipment.
Are your products compliant with hygiene standards?
Yes. For drinking water and food applications, we utilize 316 stainless steel and food-grade silicone or EPDM seals that meet strict international hygiene standards.
