What types of industrial valves does Tianjin Top Valve manufacture?

We manufacture resilient-seated butterfly valves (wafer, lug, double-flanged and grooved-end), check valves (dual plate, wafer lift, silent and ball type), resilient seat gate valves (rising stem, non-rising stem, buried and DIN pattern), globe valves for water, ammonia, vacuum and power-station service, as well as ball valves and eccentric plug valves.

Are your butterfly valves approved for drinking water?

Selected models, including 4020G, 4020L, 4325G and 4325L, are WRAS approved for potable water applications. Request our catalog to receive the approval reference and material declaration for each model.

Do you produce your own rubber seats and castings?

Yes. Our group operates Tianjin Dongfang Rubber Factory (since 1987) and Tianjin Donglian Valve Factory (since 1996), with an independent foundry, rubber compounding and moulding, a CNC machining center, assembly lines and a physical and chemical laboratory. This lets us control elastomer quality and casting integrity in-house.

Which quality and management certifications do you hold?

Our management system meets ISO 9001 quality management, ISO 14001 environmental management and ISO 45001 occupational health and safety standards, together with EU (CE) conformity for applicable products.

Can you supply valves to international flange and dimension standards?

Depending on the model, valves can be supplied with flange drilling to EN 1092 PN10/PN16, ASME/ANSI Class 125/150, BS and JIS, and our German-standard gate valves follow DIN face-to-face dimensions. Always confirm the exact standard on the model datasheet before ordering.

How can I get datasheets, drawings and a product catalog?

Request a catalog online or email victor@dytopvalve.com with your size, pressure rating, media and connection type. Our engineering team replies within 24 hours with datasheets, dimensional drawings and material specifications.

Where is your factory located and how are orders shipped?

Our factory is in the Wuxia Industrial Park, Dongli District, Tianjin, China, with fast road access to Tianjin Port. We export to customers in more than 50 countries using protective packaging and sea, air or rail freight.

CE Certification Stainless Steel Single Disc Wafer Check Valve with Enhanced Corrosion Supplier, Manufacturers

A check valve,clack valve, non-return valve or one-way valve is a valve that normally allows fluid(liquid or gas) to flow through it in only one direction.
Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are available in a wide range of sizes and costs, check valves generally are very small,simple or inexpensive. Check valves work automatically and most are not controlled by a person or any external Control; accordingly, most do not have any valve handle or stem.
The bodies(external shells) of most check valves are made of metal or palstic.

Frequently Asked Questions

Q What are the key benefits of using a single disc wafer check valve?

The single disc wafer check valve features an ultra-short face-to-face dimension, compact profile, and light weight. This substantially simplifies handling, saves pipe layout space, and lowers installation costs while offering low fluid resistance and reliable backflow prevention.

Q Can this check valve be mounted vertically?

Yes, it can be installed in both horizontal and vertical pipeline layouts. Due to its lightweight structure, additional support brackets are generally not required.

Q What body materials are available for corrosive working conditions?

For corrosive or demanding applications, we offer stainless steel grades including SS304, SS316, SS304L, and SS316L (CF8/CF8M/CF3/CF3M), as well as alloy steels like WC6, WC9, C5, and C12.

Q What manufacturing and testing standards are complied with?

The valve is designed according to API 594 and API 6D standards, certified with ISO9001, CE, and TS, and fully inspected and tested under API 598 or DIN 3230 standards.

Q How does the valve reduce water hammer?

Its integral, compact construction and short disc travel distance ensure fast closing with low impact force, effectively minimizing water hammer pressure and extending pipeline equipment longevity.

Q What pressure classes and sizes are supported?

Nominal sizes range from 2 inches to 24 inches (DN50 to DN600), with working pressures ranging from Class 150LB up to Class 1500LB.
