Titanium Ball Valve
When the through hole of the ball is aligned with the inlet and outlet channels of the valve body, the valve is in the open state. When the ball is rotated 90° and the through hole is perpendicular to the inlet and outlet channels, the valve is in the closed state.
Titanium Butterfly Valve
When the butterfly plate is in a position perpendicular to the pipeline axis, the valve is closed. When the butterfly plate is rotated 90° and is in a position parallel to the pipeline axis, the valve is open and the fluid can pass freely.
Titanium Gate Valve
When the handwheel is rotated clockwise, the valve stem drives the gate to move downward and fits tightly on the sealing surface of the valve body until it is completely closed. Rotate the handwheel counterclockwise and the valve opens.
Titanium Check Valve
When the medium has a tendency to flow back, the reverse pressure of the medium and the gravity of the valve disc itself cause the valve disc to quickly fall back to the valve seat, realizing the function of preventing the medium from flowing back.
Titanium Globe Valve
Titanium Globe Valve is mainly used to cut off or connect the medium in the pipeline, effectively control the flow of the medium, accurately adjust the flow, and ensure the safe, stable and efficient operation of the pipeline system.
Titanium Plug Valve
Titanium plug valves can be opened and closed quickly, and are used to cut off, distribute and change the flow direction of the medium. It has obvious advantages in occasions where frequent operations are required.
Electric Titanium Valve
With the help of electric drive, it can efficiently cut off, connect or adjust the flow of the medium, and is widely used in chemical, pharmaceutical and other fields with high requirements for medium control and material corrosion resistance.
Custom Titanium Valves
Customized titanium valves are valves that are tailor-made according to different working conditions, medium characteristics and materials, including titanium grades, complex functions and shapes, and can accurately match special piping systems.
Pneumatic Titanium Valve
With compressed air as the power source, the valve is opened or closed by air pressure drive. It has fast switching speed, sensitive response, and precise control of fluid flow, and is often used in chemical pipeline systems.
Commonly Titanium Grade For Valves
Each titanium grade has its own unique chemical composition, performance characteristics and scope of application. From industrial pure titanium to various titanium alloys, they have their own strengths in corrosion resistance, mechanical properties, etc., providing a wide range of options for valve manufacturing under different working conditions and media conditions.
- ASTM B265 Grade1
Gr1 has a tensile strength of about 240-345MPa, a yield strength of about 170-275MPa, and an elongation of 24%-30%. It has extremely excellent corrosion resistance, especially for oxidizing acids, neutral salt solutions, etc.
- ASTM B265 Grade2
Gr2 has a tensile strength of 345-450MPa and a yield strength of about 275-380MPa. It has good comprehensive performance and excellent corrosion resistance, and performs well in environments such as seawater, wet chlorine, and chlorite.
- ASTM B265 Grade3
Gr3 has a higher strength than Gr1 and Gr2, with a tensile strength of 450-550MPa and a yield strength of 380-485MPa. It is often used to manufacture valves that withstand higher pressures and certain corrosive environments.
- ASTM B348 Grade5
Gr5 is the most popular α+β type titanium alloy, with a tensile strength of 900-1100MPa and a yield strength of about 830-1000MPa. It is often used to manufacture valves under high pressure, high temperature and highly corrosive media conditions.
- ASTM B265 Grade7

- ASTM B338 Grade12
Gr12 contains 0.3% molybdenum (Mo) and 0.8% nickel (Ni), and has outstanding performance in resistance to crevice corrosion and stress corrosion cracking. It is often used in valves in the fields of seawater desalination, offshore oil extraction, etc.
Manufacturing Titanium Valves
Manufacturing titanium valves is a complex and precise process involving a variety of technologies. Forging significantly improves the mechanical properties of titanium valves and is suitable for manufacturing valves that withstand high pressure and harsh working conditions. Casting shows cost and efficiency advantages in the production of complex-shaped valves. CNC Machining meets the manufacturing needs of small, precision valves with high precision and consistency. Welding is used for part connection and defect repair, while surface treatment further improves the corrosion resistance, wear resistance and appearance quality of titanium valves.
Forging Titanium Valves
Forging significantly improves the structure and mechanical properties of titanium. The internal grains are refined and the streamline distribution is more reasonable, thereby improving the strength, toughness and fatigue resistance of the valve. After the blank reaches the appropriate size and structure state through upsetting, drawing and other processes, it is die forged. Die forging is to put the blank into a pre-designed mold cavity and plastically deform it under the action of the forging equipment to obtain a forging with the same shape as the mold cavity. The design and manufacturing accuracy of the mold play a key role in the dimensional accuracy and surface quality of the valve.
Casting Titanium Valves
Casting is a manufacturing technology that injects liquid titanium into a specific mold cavity and obtains the desired shape flange after it cools and solidifies. Titanium has a high melting point of about 1668℃. Wstitanium uses a vacuum consumable arc furnace for smelting to ensure the quality and purity of the titanium liquid.
Melting in a vacuum environment can effectively reduce the reaction of titanium liquid with impurity elements such as oxygen and nitrogen in the air, and avoid the performance of the valve being affected by the mixing of impurities. Special mold materials are required when casting titanium valves. For example, graphite, yttrium oxide ceramics, etc., these materials have good high temperature resistance and chemical stability, and can resist the erosion of titanium liquid during the casting process. At the same time, a special protective coating is applied to the surface of the mold to further isolate the titanium liquid from the mold, prevent chemical reactions between the two, and ensure the surface quality and dimensional accuracy of the casting.
The cooling rate in casting has a significant effect on the microstructure and performance of titanium valves. Rapid cooling can refine the grains and improve the strength and toughness of the valve. Slow cooling may lead to coarse grains and reduce the performance of the valve. Therefore, Wstitanium rationally designs the mold structure, controls the pouring temperature and cooling medium, and precisely controls the cooling rate to obtain the ideal microstructure and performance.
CNC Machining Titanium Valves
CNC machining is an advanced technology that uses digital programs to control machine tool movement and tool trajectory. CNC machining has the advantages of high precision and high efficiency, and can realize the manufacture of complex-shaped titanium valves, ensuring dimensional accuracy and surface quality. Especially for small and precise titanium valves, CNC machining is an irreplaceable manufacturing technology.
According to the shape, size, accuracy and titanium grade required by the titanium valve drawing (stp, igs, x-t format), select the appropriate machining center and tool (CBN). Then use CAD/CAM software for programming, convert the machining parameters and tool paths into programs, and input them into the CNC machine tool control system. During the programming process, the machining characteristics of titanium materials, such as large cutting force, high cutting temperature, easy sticking of the tool, etc., should be fully considered, and the cutting parameters should be reasonably selected to ensure the machining quality and tool life. CNC machining requires a small cutting depth, feed rate and appropriate cutting speed to obtain good surface finish and dimensional accuracy.
Heat Treatment
Titanium valves usually need to be heat treated to eliminate forging stress and improve structure and performance. Common heat treatment processes include annealing, solution treatment and aging treatment. Annealing is the process of heating the forging to a certain temperature, keeping it warm for a certain period of time and then slowly cooling it. It is mainly used to eliminate forging stress, reduce hardness and improve plasticity. Solution treatment is to heat the titanium alloy to a high-temperature single-phase region, keep it warm for a certain period of time and then quickly cool it so that the alloy elements are fully dissolved in the matrix to form a uniform solid solution structure and improve the strength and toughness of the alloy. Aging treatment is to keep the alloy after solution treatment at a certain temperature for a certain period of time to decompose the supersaturated solid solution and precipitate a dispersed strengthening phase to further improve the strength and hardness of the alloy.
Surface Treatment
In order to improve the corrosion resistance and appearance quality of titanium valves, it is usually necessary to surface treat the forged valves. Common surface treatment methods include pickling, passivation, sandblasting, etc. Pickling is to use acid solution to remove impurities such as oxide scale and oil stains on the surface of the valve to make the surface smooth. Passivation is to form a dense oxide film on the valve surface to improve its corrosion resistance. Sand blasting uses high-speed sand to impact the valve surface to remove surface impurities and create a certain degree of surface roughness, which is conducive to subsequent painting or other surface treatments.
Titanium Valve Seal
Seal refers to the parts or measures that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the interior of the equipment. Titanium valve seals are a key link in industrial fluid control systems. Sealing performance is directly related to the safety of the system. Good sealing can ensure that the medium flows along the predetermined path and avoid waste of resources, environmental pollution and even safety accidents caused by leakage. The Wstitanium sealing performance test follows the ASME B16.104 standard.
- Static Sealing:
Static sealing: refers to the sealing between two stationary surfaces, such as the sealing between the valve body and the valve cover, and the sealing between the valve seat and the valve body. Static sealing is mainly achieved by using sealing gaskets, sealants, etc. The function of the sealing gasket is to fill the microscopic gap between the joint surfaces and prevent the leakage of the medium under a certain compression force. Common static sealing gasket materials include non-metallic materials (such as asbestos rubber sheet, polytetrafluoroethylene, nitrile rubber (NBR), ethylene propylene rubber (EPDM), fluororubber (VITON), etc.) and composite materials (such as metal spiral wound gaskets, metal coated gaskets, etc.).
- Dynamic Sealing
Dynamic sealing: mainly refers to the sealing between the valve stem and the stuffing box, the purpose of which is to prevent the medium in the valve from leaking as the valve stem moves. Commonly used packings include asbestos packing, polytetrafluoroethylene braided packing, rubber O-rings, etc. In addition, there are new dynamic sealing forms such as bellows seals. Bellows seals do not require packing and realize the movement of the valve stem through the expansion and contraction of the bellows while ensuring the sealing performance. They are suitable for occasions with extremely high sealing requirements, such as valves for conveying highly toxic, flammable and explosive media.
