Valve Chain Material Options
Tuohai offers a range of materials to suit your equipment and how you use it. If you need other custom materials, let us know.
Stainless Steel Valve ChainTuohai can offer valve chains in 304, 316, and other stainless steel grades for use in various outdoor or corrosive environments.
Carbon Steel Valve ChainThis type of valve chain has the widest range of uses. We offer several finishes to suit your operating environment and appearance needs.
Solid Brass Valve ChainThis valve chain is made of solid brass. It stands out during use, making it easy to quickly tell it apart from other parts. It also offers some corrosion resistance.
Valve Chain Surface Finishes
Tuohai offers a range of finishes for your valve chain to suit different operating environments and appearance needs:
- Zinc electroplating: suitable for indoor use or mildly corrosive environments. It provides everyday rust protection for carbon steel valve chain.
- Hot-dip galvanizing: usually has a thicker zinc coating. It suits outdoor use and environments with frequent moisture or rain, providing longer-lasting rust protection for carbon steel valve chain.
- Copper plating: suitable for equipment used in dry indoor areas where appearance matters. It helps the chain match the overall look of the equipment.
- Polishing: suitable for stainless steel and solid brass valve chain. It makes the surface shinier and suits indoor use and applications where a clean appearance matters.
- Passivation: used on stainless steel valve chain to further improve its corrosion resistance. It is suitable for damp or corrosive environments.
Tell us about your operating environment and the look you need. We will recommend a suitable finish based on the chain material.

Custom Valve Chain Lengths
Whether you are fitting new equipment or replacing an old chain, Tuohai can supply valve chain in continuous lengths or specified lengths to suit your needs.
Continuous lengths let you cut the chain yourself to suit different equipment.
We can make cut lengths to your drawings or samples to better suit your valve installation height and reduce measuring and cutting on site.
Tuohai Production and Customization Services
From bulk production to custom orders, we supply chain to fit your valve equipment.
Our automated valve chain production equipment can run continuously for 24 hours. This improves production efficiency and reduces labor costs. It also ensures that every link has a consistent size and shape, allowing the chain to run smoothly on a matching valve chainwheel.
We can customize the valve chain(lock link chain used in chainwheels), including its shape, material, link dimensions, chain length, and finish, to match your valve chainwheel. We can also customize matching connecting links, labels, and packaging to make assembly or resale easier for you.

You can provide chainwheel specifications, chain drawings or samples. We will help you determine the valve chain size or specifications you need and suggest materials and finishes for your operating environment.
After discussing the details with you, we will quote based on the final product requirements and order quantity. If you also need connecting links or other custom options, we can include them in the quote so you can see the detailed pricing.
Once the order details are confirmed, we will arrange production using the agreed material, link dimensions, chain length and finish.
We offer a one-stop valve chain purchasing service. We can supply matching accessories such as connecting links, as well as labels and custom packaging, so you do not need to work with several suppliers.
We support inspection before shipping. You can arrange it yourself or send a third-party inspection company to our factory. We will help the inspectors check the products, including the valve chain link dimensions, chain length, surface appearance and quantity, against the order requirements.
If there are any details you want checked closely for this order, let us know in advance. We will help arrange the checks so you can get a detailed view of the actual products before they leave our factory.
We can pack your valve chain on reels or in bags, cartons or wooden boxes. We can also customize the packaging to suit your storage, assembly or sales needs. Your logo or design can be printed on the packaging. Product specifications, quantities and part numbers can be shown on boxes and labels to make the goods easy to identify and store when they arrive.
If you need complete sets for assembly or are buying several specifications in one order, we can assemble the chains and connecting links into sets or group them by specification for packing. This reduces the sorting you need to do when the goods arrive.
We work with several experienced logistics companies to provide quality shipping services based on your order quantity, delivery location and other needs. Options include air, sea and rail transport, express delivery and more. We ensure that your goods arrive safely and on time at your chosen location.
We check the link dimensions and shape against the chainwheel specifications, chain drawings or a sample of the original chain. Valve diameter alone is not enough to determine the chain specifications. Send us the information you have, and we will help you choose a chain that matches your chainwheel.
