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 bathroom valves, industrial pipelines, and wall-hung boiler valves.
  • Flexible material selection: Brass, stainless steel (304/316), high-purity alumina ceramic, and engineering plastics (POM/PTFE) are available to match hygiene and durability standards.
  • Precision parameter customization: Diameter support (Φ5-Φ50mm), multiple interface types (thread/clamp/welded), and specific opening angles (90°/180°/custom).
Quality Assurance
1. Strict Selection of Raw Materials

Metal materials are spectroscopy tested; ceramic sheets are sintered at 1700℃ with Ra0.1μm finish; seals utilize food-grade silicone or EPDM with temperature resistance from -20℃ to 120℃.

2. Precision Machining

Utilizing CNC lathes and five-axis machining centers, we control accuracy within ±0.005mm for key parts, ensuring smooth operation without jamming.

3. Full Performance Testing

Each batch passes 12 core tests: Sealing (10 bar for 30 min), Life (500,000+ cycles), Corrosion (48h salt spray), and Temperature shock tests.

Bathroom Building Materials HVAC Systems Water Conservancy Household Appliances Industrial Equipment Agricultural Irrigation Chemical Pipelines
Frequently Asked Questions
What materials can I choose for my custom valve core?
We offer a variety of materials including Brass, Stainless Steel (304/316), High-purity Alumina Ceramic, and Engineering Plastics (POM/PTFE) to suit different budget and performance requirements.
What is the machining accuracy of your valve cores?
Using high-precision CNC and five-axis machining centers, we control the accuracy of key sealing surfaces and valve core holes within ±0.005mm.
How many cycles can the valve core withstand?
Our valve cores undergo rigorous life cycle testing and are designed to exceed 500,000 opening and closing cycles without performance degradation.
Are the valve cores suitable for extreme temperature conditions?
Yes, by using EPDM or food-grade silicone seals and specialized ceramic plates, our valve cores can operate stably in temperatures ranging from -20℃ to 120℃.
Can you customize the interface and diameter?
Absolutely. We support customization of diameters from Φ5mm to Φ50mm and various interface types including threaded, clamped, and welded connections.
What pressure levels are tested before shipping?
Every batch must pass a sealing test where no leakage is allowed under 10 bar of pressure for a minimum of 30 minutes.
