ZECO manufactures and stocks a wide range of Titanium valves, including: Titanium Ball Valves, Titanium Needle Valves, Titanium Check Valves, Titanium Globe Valve, Titanium Gate Valves , and Titanium Y Strainer.
What is a Titanium Ball Valve?
Titanium alloy valves are known for their high strength to weight ratio. Titanium alloy is a low-density strong metal with good ductility.
Titanium valves are available in a variety of material grades from the most commonly used Grade 2 to alloyed titanium Gr. 5 ,Gr. 7 and Gr. 12. Titanium alloys are aliased R50400, R50550 and R56400 in UNS. The DIN standards are named 3.703, 3.7035, 3.7164, and 3.7165, while the ASTM designation is A182 316Ti.
Corrosion Resistance Characteristics of Titanium Ball Valves
- Titanium ball valves is almost no corrosion in the atmosphere, freshwater, seawater, high-temperature water vapor.
- Titanium ball valves and titanium valves are very resistant to corrosion in alkaline media.
- Titanium ball valve has strong anti-ion ( Cl ) ability and excellent resistance to ion corrosion.
- The corrosion resistance of the titanium ball valves in the reducing acid depends on whether the medium has a corrosion inhibitor
- Lightweight, high mechanical strength, wide application, military field.
Application of Titanium Ball Valves
- Seawater Desalination
- Pulp and Paper
- Petrochemical industry
- Smelting
- Aviation and Military
The requirement olefins are expected to grow by 4% or more in the next several years. The packaging and automobile industries are important users of polymers. The market requires high-quality polymers. And valves play an important role in the powder discharge system of the polymer processing unit.
In April 2019, C-Tech Science and Technology Co., Ltd. has successfully designed and produced the High performance fully metal seated Ball Valves for the PDS of China local Polymer Processing Unit. It is the Unipol gas-phase polypropylene unit of DOW, and the minimum operation cycles is 0.5million (≥0.5 million cycles).
Frequent cycling, high temperatures and high-speed stroke time can damage valve seats and stem, and resulting in increased fugitive emissions.
To overcome these abrasive conditions, the design was adopted: The valve type: Fully metal seated Ball Valve, Trunnion Mounted. Special and patent seat design maintains tight shut-off performance to FCI 70-2 Class VI criteria. Integrated stem design and patented sealing packings can be easily retightened to avoid/reduce fugitive emission. Valve Ball and Seat are coated with Tungsten Carbide. Special Coating method and Equipment were adopted. We ensure the ball surface hardness is HRC76, and the seat surface hardness is HRC68. And the thickness of the coating is from 200 to 300 microns. The full-bore design of C Tech PDS valves ensures non-turbulent ow without pressure drops. It also minimizes the likelihood of solids build-up that can reduce medial ow.
