 I.Preface

With the increasing emphasis on health and quality of life, water purifiers, as important household appliances that provide clean drinking water, have received more attention and demand in the market. Among them, the diverter valve, as one of the crucial components of water purifiers, directly affects users' usage 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 Manufacturers of Water Purifiers

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 having 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 have rich order acceptance capabilities and export experience, be able to handle orders of various specifications in a timely and efficient manner, and be able to export 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 guarantees for product quality.

3.Able to accept buyer's OEM orders

With the intensification of market competition, more and more brand owners choose to transfer production to OEM/ODM manufacturers. Therefore, excellent contract manufacturers should be able to accept buyer's OEM orders and be able to 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's just a small diverter valve, the consistency of product quality relies on this machine for testing. Typically, we apply pressure of 150PSI (11kg/cm2) of high water pressure to this machine and continuously operate it with on-off cycles. It needs to operate 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 valve, also known as diverters or splitters, are mostly used in countertop water purifiers. These valves allow you to quickly select between filtered and unfiltered water at the faucet. Its nut (commonly referred to as a "flower nut") can be securely fastened onto the kitchen faucet outlet, 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 water from the faucet to the filter. After water is dispensed, just turn the handle of the diverter downward to close it, so that next time you can use the kitchen faucet as usual (for dishwashing, cleaning the sink, etc.). Below are several common specifications of diverter valve:

1.Single-tube outlet diverter valve

The single-tube outlet diverter valve is usually suitable for water purifiers with gooseneck faucets. Its function is to control the switching between the water purifier and tap water, allowing users to switch between filtered water and tap water as needed. This type of diverter valve typically has a simple and clear operating interface, making it easy for users to use.

2.Two way diverter valve

The function of the two way diverter valve is similar to that of a single spout water switch, allowing for the simultaneous control of tap water and filtered water. Typically used for water purifiers without a gooseneck faucet, the main difference from a single spout water switch is that the outlet for filtered water returns to the switch, flowing out from the clean water outlet of the switch. This allows the water purifier to be placed on the countertop or under the sink without restriction, providing a more convenient water usage experience.

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 of zinc alloy are characterized by lighter weight and lower cost. Some manufacturers have developed a series of zinc alloy-based switches in order to win orders at a lower price. The biggest drawback of zinc alloy is that it is prone to oxidation and bubbling when in contact with water, and there are concerns about the release of toxins from the surface of the zinc alloy.

(3) Plastic Material

The plastic material diverter valve is usually used in inexpensive water purifiers, and the diverter valve is mostly made of ABS, which has the characteristics of low cost and lightness, suitable for use in homes and small commercial places. Many European and American countries have begun to require drinking water products to meet lead-free regulations, and plastic toggle switches do not raise concerns about lead release, making them a popular option in many European and American countries recently.

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 have a price difference of one to two US dollars,

First: The purity of copper material and whether it contains lead or not can cause significant price differences. Lead is a softener that, when added to copper material, makes it easier to process and cut; removing lead makes processing more difficult and leads to higher production costs.

Second: The interface agent used in the diverter valve is also a major factor in its price difference. Copper diverter valve require different parts to be assembled, which requires the use of an oxygen-deficient adhesive to bond two or more parts together. If NSF-certified and non-toxic oxygen-deficient adhesives are used compared to uncertified ones, the price difference per kilogram can be 4-5 times. Additionally, lubricating oil is required to ensure smooth switching without leaks, and the price difference between DOW Dow lubricating oil and regular lubricating oil can be up to 5-6 times per liter.

Third: The material of the internal structure, the switching mechanism for switching purified water and raw water, using copper ball structure (better durability) compared to long shaft core structure (usually made of plastic material, short lifespan) can also differ in price by several times.

Fourth: Conscientious manufacturers will add a stainless steel filter screen at the water inlet of the diverter valve to filter out fine sand and stones in tap water, protecting the lifespan of the diverter valve.

In summary, the selection of specifications and materials for the diverter valve, as one of the crucial components of a water purifier, directly impacts the performance and quality of the water purifier. Choosing an excellent OEM/ODM manufacturer and suitable switch valve product can provide users with safe, healthy drinking water, thus enhancing their quality of life.
