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.
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 sealing plates offer high wear resistance.
Precision Parameter Customization
Supports adjustments to diameter (Φ5–Φ50mm), interface type (thread/clamp/welded), opening angle (90°/180°/custom), and sealing level (IP65+). Perfect compatibility with existing valve bodies.
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 finished products.
1
Strict Raw Material Selection
Metal materials tested by spectroscopy. Ceramic sheets use high-purity alumina sintered at 1700℃. Seals use food-grade silicone or EPDM.
2
Precision Machining
CNC lathes and five-axis centers control accuracy within ±0.005mm. Automated assembly lines ensure product consistency.
3
Full Performance Testing
12 core tests: sealing (10 bar), life test (500,000+ cycles), corrosion (48h salt spray), and temperature shock.
🚿
Bathroom & Materials
Shower valve cores, thermostatic cores, smart toilet inlet valves.
🌡️
HVAC Systems
Boiler three-way valves, underfloor heating manifold valve cores.

Q1 What materials are available for custom water valve cores?
We offer brass, stainless steel (304/316), ceramic, and engineering plastics (POM/PTFE). For food-grade applications, 316 stainless steel is recommended. For high-temperature environments, ceramic sealing plates provide superior wear resistance.
Q2 Can you customize valve core dimensions for existing valve bodies?
Yes. We support customization of diameters (Φ5–Φ50mm), interface types (threaded, clamp, welded), and opening angles. Our engineering team can perform reverse modeling from your samples to ensure a perfect fit.
Q3 What quality tests are conducted before shipment?
Each batch undergoes 12 core tests, including sealing tests at 10 bar, life cycle tests (500,000+ cycles), 48-hour salt spray corrosion tests, and temperature shock testing.
Q4 Are your valve cores suitable for high-pressure industrial use?
Absolutely. Our industrial valve cores are machined using CNC and five-axis centers to tolerances of ±0.005mm, ensuring smooth operation under high-pressure and demanding conditions.
Q5 What industries do your water valve cores serve?
We serve various industries including sanitary ware, HVAC (boilers/underfloor heating), water conservancy (irrigation/municipal), home appliances (washing machines/purifiers), and industrial chemical equipment.
Q6 How do you ensure long-term durability?
Durability is ensured through high-purity alumina ceramic sheets (sintered at 1700℃), food-grade EPDM seals, precision CNC machining, and rigorous simulation of over 500,000 opening/closing cycles.
