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 household bathroom valves, industrial pipelines, and wall-hung boilers. Optimized tactile damping achieves "light turning for precise temperature control".

Flexible Material Selection

Offers combinations including brass, stainless steel (304/316), ceramic, and engineering plastics (POM/PTFE). High-purity ceramic sealing plates offer more than 3× the wear resistance of traditional materials.

Precision Parameter Customization

Supports adjustments to diameter (Φ5–Φ50mm), interface types (thread/clamp/welded), and custom opening angles (90°/180°). Reverse modeling ensures compatibility with existing valve bodies.

Quality Assurance
1
Strict Selection of Raw Materials: All metal materials are tested by spectroscopy. Alumina ceramics are sintered at 1700℃ with Ra0.1μm finish. Seals are food-grade silicone or EPDM (-20℃ to 120℃).
2
Precision Machining: Using CNC lathes and five-axis centers, machining accuracy is controlled within ±0.005mm, ensuring smooth operation without jamming and high consistency.
3
Full Performance Testing: 12 core tests including 10 bar sealing test for 30 mins, 500,000+ cycle life test, 48-hour salt spray test, and temperature shock testing.
Application Areas
Bathroom & Building Materials

Shower valve cores, thermostatic cores, and smart toilet inlet valves.

HVAC Systems

Three-way valves for wall-hung boilers and underfloor heating manifolds.

Water Conservancy

Agricultural irrigation and municipal water supply pipeline valves.

Household Appliances

Washing machine inlets and water purifier wastewater ratio valves.

Industrial Equipment

Hydraulic system controls and corrosion-resistant chemical pipeline cores.

Frequently Asked Questions
Q1. What materials are available for custom water valve cores?
We offer brass, stainless steel (304/316), ceramic, and engineering plastics (POM/PTFE). 316 stainless steel is recommended for food-grade needs, while ceramic is ideal for high-wear environments.
Q2. What parameters can be customized for valve core dimensions?
We support customization of diameter (Φ5–Φ50mm), interface type (thread, clamp, or welded), opening/closing angles (90°, 180°, or custom), and sealing levels up to IP65 and above.
Q3. How do you ensure the durability of the valve cores?
Each batch passes 12 tests, including a 10 bar sealing test, a 500,000+ cycle life test, a 48-hour salt spray test, and temperature shock testing before shipment.
Q4. Can you manufacture valve cores for industrial applications?
Yes. We serve industries including sanitary ware, HVAC systems, water conservancy, household appliances, and industrial equipment like hydraulic systems and chemical pipelines.
Q5. What is the machining precision for your valve components?
Using high-end CNC and five-axis machining centers, we control the accuracy of critical components to within ±0.005mm to ensure smooth, jam-free operation.
Q6. What temperature range can the valve seals handle?
Our food-grade silicone or EPDM seals are rated for temperatures ranging from -20℃ to 120℃, making them suitable for alternating hot and cold water conditions.
