I. Preface

With the increasing emphasis on health and quality of life, water purifiers, as essential household appliances that provide clean drinking water, have garnered more attention and demand in the market. Among them, the diverter valve, one of the crucial components of water purifiers, directly affects users’ experience and water safety. This article will delve into OEM/ODM manufacturers of water purifier switch valves in Taiwan, also known as water dividers, and provide a detailed list of manufacturers and their information to help consumers and industry professionals better understand the advantages and characteristics of the products.

II. Criteria for Selecting OEM/ODM

When choosing OEM/ODM manufacturers of water purifiers, several key factors need to be considered to ensure product quality and performance. The following are the main criteria for selecting OEM/ODM manufacturers of water purifiers:

1. The manufacturer should be a registered company in Taiwan

Excellent OEM/ODM manufacturers should be registered as legitimate companies in Taiwan, complying with local laws and regulations, and possessing a good corporate reputation and legal operating foundation. Registered companies can provide more legal protection and consumer rights protection, ensuring product quality and compliance, while also helping to establish long-term cooperative relationships.

2. Have the ability to accept orders and export experience

Excellent OEM/ODM manufacturers should possess extensive order acceptance capabilities and export experience. They should be able to handle orders of various specifications in a timely and efficient manner and be capable of exporting products to various parts of the world to expand market share and enhance product competitiveness. Manufacturers with export experience usually understand international market demands and standards, providing more assurance for product quality.

3. Able to Accept Buyer’s OEM Orders

With the intensification of market competition, an increasing number of brand owners are choosing to transfer production to OEM/ODM manufacturers. Therefore, excellent contract manufacturers should be able to accept buyer’s OEM orders and flexibly adjust production plans and product specifications according to customer requirements. Maintaining good communication and cooperation with buyers to jointly create high-quality products is an important consideration when choosing a contract manufacturer.

4. Owning Own Production Lines

OEM/ODM manufacturers with their own production lines can typically better control the production process and product quality. They can flexibly adjust production plans according to customer needs, respond promptly to market changes, and ensure timely delivery and product quality stability. Additionally, manufacturers with their own production lines can control production costs and enhance product competitiveness.

5.Equipped Product Testing Laboratory

An equipped laboratory should ideally have the following equipment:

(1) Optical Emission Spectrometer

This can quickly measure a wide range of metal alloy elements such as copper, iron, aluminum, nickel, titanium, magnesium, etc. As more customers require lead-free copper materials, it’s essential to ensure that the copper materials supplied do not contain lead. Using an Optical Emission spectrometer is the most accurate and precise method for this purpose.

(2) Salt Spray Testing

This test primarily evaluates the weather resistance of product surfaces. Conducting natural environmental exposure tests is time-consuming and subject to numerous uncontrollable variables. To efficiently and objectively assess whether the chrome plating layer on our switches can withstand UV radiation and the corrosive effects of acidic or alkaline substances, we regularly use salt spray testing equipment to accelerate the testing process.

(3) Product Lifetime Reliability Testing

Although it is just a small diverter valve, the consistency of product quality relies on this machine for testing. Typically, we apply a high water pressure of 150 PSI (11 kg/cm²) to this machine and continuously operate it with on-off cycles. It needs to function 110,000 times without leaking, and afterwards, the tactile sensation should still feel smooth when turned by hand to be considered qualified. Samples tested are then scrapped, and for every production batch of 1000 units, one unit undergoes durability testing.

Adhering to and implementing the above conditions helps ensure that the diverter valve products meet high-quality standards, providing consumers with peace of mind and a healthy water experience.

III. Specifications and Materials of Diverter Valve (Also Known as Diverters)

Diverter valves, commonly referred to as diverters or splitters, are primarily used in countertop water purifiers. These valves enable rapid selection between filtered and unfiltered water at the faucet. The nut, often called a “flower nut,” securely attaches to the kitchen faucet outlet and is suitable for most connections of 1/4″ or 3/8″ unidirectional PE water pipes, or 3/8″ bidirectional PE water pipes for countertop filters.

When you need to filter water, simply turn the handle of the diverter valve to redirect water from the faucet to the filter. After dispensing water, turn the diverter handle downward to close it, allowing normal use of the kitchen faucet next time (for dishwashing, sink cleaning, etc.). Below are specifications for a few common types of diverter valves:

1. Single-tube outlet diverter valve

The single-tube outlet diverter valve is typically suitable for water purifiers equipped with gooseneck faucets. Its purpose is to control the switch between the water purifier and tap water, enabling users to alternate between filtered and tap water as required. This type of diverter valve generally features a straightforward operating interface, ensuring ease of use for users.

2.Two way diverter valve

The function of the two-way diverter valve is akin to that of a single-spout water switch, enabling simultaneous control of tap water and filtered water. It is commonly employed in water purifiers that do not feature a gooseneck faucet. The key distinction from a single-spout water switch lies in the outlet for filtered water returning to the switch, flowing out from its clean water outlet. This setup facilitates flexible placement of the water purifier on countertops or beneath sinks, enhancing the convenience of water usage.

3.Material of the diverter valve

The material of the diverter valve has a significant impact on the durability and safety of the product. Common Material of the diverter valve include:

(1) Copper-plated Chrome

Switches made of copper-plated chrome exhibit excellent durability and corrosion resistance. They can maintain stability and durability for long periods in humid environments while also providing a visually pleasing appearance.

(2) Zinc Alloy

Switches made from zinc alloy are known for their lighter weight and lower cost. Certain manufacturers have introduced a range of zinc alloy-based switches to secure contracts at competitive prices. The main disadvantage of zinc alloy is its susceptibility to oxidation and blistering when exposed to water, along with concerns about potential toxin release from its surface.

(3) Plastic Material

The plastic diverter valve is commonly employed in affordable water purifiers, typically crafted from ABS, renowned for its cost-effectiveness and lightweight properties. This material is well-suited for residential and small commercial applications. In response to increasing regulations in Europe and America stipulating lead-free standards for drinking water products, plastic toggle valves have gained popularity due to their assurance against lead leaching.

Diverter valve made of different materials vary in durability, safety, and aesthetics. Consumers can choose based on their needs and budget.

IV. the price difference of the interface agent used in the diverter valve. A small copper diverter valve can exhibit a price variance of one to two US dollars.

Firstly: the purity of the copper material and the presence of lead significantly influence pricing. Lead acts as a softener, facilitating easier processing and cutting of copper. The absence of lead increases production complexity and costs.

Secondly:the choice of interface agent in the diverter valve is pivotal. Copper diverter valves necessitate diverse components for assembly, requiring an oxygen-deficient adhesive to fuse multiple parts. Use of NSF-certified and non-toxic oxygen-deficient adhesives, compared to uncertified alternatives, can lead to a price differential of 4-5 times per kilogram. Furthermore, ensuring seamless switching without leaks demands lubricating oil, with DOW Dow lubricants commanding a price premium of 5-6 times per liter over regular alternatives.

Thirdly: differences in internal material composition affect pricing. Opting for a copper ball structure, known for durability, over a short-lived plastic-based long shaft core for switching between purified and raw water, can result in substantial cost discrepancies.

Fourthly: conscientious manufacturers often incorporate a stainless steel filter screen at the water inlet of diverter valves. This feature effectively filters fine sand and stones from tap water, enhancing the valve’s longevity.

In conclusion, the choice of specifications and materials for the diverter valve, a critical component of a water purifier, significantly influences the performance and quality of the purifier. Opting for a reputable OEM/ODM manufacturer and a suitable switching valve product can ensure users have access to safe, healthy drinking water, thereby improving their quality of life.
