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 focus on the research, development, and production of high-performance water valve cores. With "precise fit, superior quality, and customization" as our guiding principles, we provide cost-effective valve core solutions for sanitary ware, HVAC, water conservancy, and home appliances.

Product Features
Multi-scenario Adaptability

Customized flow curves and torques for bathroom valves, industrial pipelines, and water purification systems. Optimized tactile damping ensures precise temperature and flow control.

Flexible Material Selection

Available in brass, stainless steel (304/316), ceramic, and engineering plastics (POM/PTFE). High-purity ceramic plates offer 3x the wear resistance of traditional materials.

Precision Customization

Supports diameters from Φ5mm to Φ50mm. Interface types include thread, clamp, or welded. Opening angles can be customized (90°/180°) with sealing up to IP65+.

Quality Assurance
1
Raw Material Control: Metals are spectroscopy tested; ceramic sheets are sintered at 1700℃ with Ra0.1μm finish; seals utilize food-grade silicone or EPDM (-20℃ to 120℃).
2
Precision Machining: CNC and five-axis centers control tolerances within ±0.005mm, ensuring smooth operation without jamming and maintaining high product consistency.
3
Rigorous Testing: 12 core tests per batch, including 10 bar pressure sealing, 500,000+ cycle life tests, 48-hour salt spray corrosion tests, and temperature shock assessments.
Application Areas
Bathroom
HVAC Systems
Water Conservancy
Appliances

Frequently Asked Questions
Q1: What materials are available for custom water valve cores?
We offer brass, stainless steel (304/316), ceramic, and engineering plastics like POM or PTFE. Selection depends on your application—316 stainless for food-grade hygiene or ceramic for high-temperature durability.
Q2: Can you customize valve cores to fit our existing valve body?
Yes. Our engineering team can perform reverse modeling from your samples to ensure the custom core is a perfect drop-in replacement, requiring no changes to your current assembly line.
Q3: What sizing and interface ranges do you support?
We support diameters from Φ5mm to Φ50mm. Connection types include threaded, clamp, and welded interfaces, with custom opening angles available.
Q4: What quality testing protocols are in place?
Every batch undergoes 12 core tests, including 10 bar leakage tests for 30 minutes, 500,000-cycle life simulation, salt spray corrosion testing, and thermal shock resistance.
Q5: Are these suitable for high-pressure industrial use?
Absolutely. While we serve residential bathroom needs, our industrial-grade valve cores are specifically designed for high-pressure hydraulic systems and corrosive chemical environments.
Q6: How do you maintain machining consistency?
By utilizing CNC lathes and five-axis machining centers, we maintain tolerances within ±0.005mm. Automated assembly lines further minimize human error across large production runs.
